Add in some macular degeneration. That would be me. VBG You may remember the thread I started where I asked about computing the aspect ratio of a monitor based on screen resolution. I've found @50 different resolutions you may come across, depending on hardware. (I assume you meant "~50".) Assuming you mean native resolution of the monitor, I'm surprised there are _that_ many. I'd have expected 5 to 10: 4:3, 16:9, 16:10, and one or two others. (Twice as many if you include them rotated, i. e. 3:4 etcetera.) [] I'd already learned some monitors cannot display light greys, light blues, and thin lines. Although the line issue may be tied to the color of the line. I don't know. I'd be surprised if any monitor _used at its native resolution_ can't display a one-pixel-wide line, unless as you say it's unable to distinguish the colour of the line from the surrounding area (in which case the thickness of the line wouldn't have much effect). I learned the best LCD panel for display of colors is an ISP type panel. So, that's what I bought. The best interpretation of that (to me it's "internet service provider"!) is "image signal processor". I'm dubious, but if that's what you've found ... And boy, am I glad I did. I learned some monitors also cannot display light yellows! 0. With any monitor that has a "native resolution", i. e. pixels, which means any modern flat-screen monitor, using it at other than its native resolution (or an integral fraction thereof) will result in _some_ blurring. This may still be acceptable as the cost for not wearing your glasses. (It won't apply to a CRT monitor!) Correct on the blurring, but depending on what you buy for an monitor, and the settins you use, blurring may not be noticeable, although the extent of failure of your eyesight may come into play. Agreed. Though intuitively using the wrong resolution seems very wrong, the blurring _can_ be not very noticeable - and, as you say, if you have some eyesight conditions it may be not noticeable at all. I'd rather be able to read the screen with barely noticeable blurring, than fight with the recommended resolution to figure out what is on the screen. I find native resolution the best, if only for psychological reasons (if I "know" there's blurring due to using the wrong one, then I think I'll see it even if I can't really!). With my situation, the blurring of the screen is not noticeable. More than likely, that's the result of a combo of factors, it's not a cheapie monitor, It's a monitor and not a TV, the chosen alternative resolution has the same aspect ratio as the native resolution. The right aspect ratio won't _necessarily_ avoid blurring due to wrong resolution - for example, 640×480 and 800×600 are both 4:3, but not in integral ratio. The "everything bigger" effect may more than compensate for that for people with poor sight though. 1. Some modern monitors and graphics cards talk to each other, which might mean that the graphics card knows what shape the monitor is, and may refuse to offer "incorrect" resolutions. What's your definition of "incorrect" resolutions? Not mine, the hardware/firmware! I haven't really looked into it as I tend to use native anyway, but I have encountered cases where I know the graphics card can offer some resolutions that Windows is not listing because it knows they don't suit a particular monitor - either because the user has told Windows what monitor they're using, or because the monitor has "told" Windows something about itself over plug-and-play. If magnification is something you need, you will want an alternative resolution that has the same aspect ratio as the native resolution. With the Windows units I've tested, dragging the resolution slider up and down will show multiple options, but only those resolutions that are listed when you are not dragging the slider have the same aspect ratio. Magnification _without_ *blurring* would need integral ratios. It is _possible_ that the integer could be different in the two dimensions, though I suspect the right ratios for that don't exist in practice. It's more likely, if you need magnification, that you won't see the blurring caused by a non-integral ratio, and as you say in that situation ensuring the same aspect ratio will give you magnification without *distortion*, which is probably more important. [] If you're using a laptop, need magnification, and are unwilling to buy an external monitor, I'd recommend giving up now. SVGA (800X600) just won't display enough data on the screen to be useful, IMO. Certainly, a lot of modern software - especially web page design - is no friend of the visually impaired, in many ways. (Many web designers assume far too big a screen even for the rest of us, but that's a different subject!) But you are right. I do have an interest in access for the VH/VI, so I attend the odd show on the matter. For those for whom magnification does work - i. e. they do have some sight - blowing up just part of the screen seems to be the preferred option, rather than using SVGA or less. 2. The range of ratio "corrections" (distortions) available will be limited - possibly only to the difference between 16:9 and 4:3. You can expand the range somewhat by turning your monitor sideways: modern OSs (I think XP on, possibly earlier) have the ability to turn the picture sideways, though how to invoke it isn't widely known. (Sometimes it's as simple as the arrow keys with other keys.) I think the need for rotating the monitor is generally limited. You're not going to gain anything visually from what I can see with my testing on this monitor. Instead of having 1920 X 1200, you have 1200 X 1920. If you have the form of astigmatism that _just_ makes you see the world with the wrong aspect ratio, it _could_ help. Depends on whether your distortion matches (in the other direction) one of the distortions available by playing with resolution settings, monitor rotation, and so on. I agree, though, monitor rotation is less used these days; it first became a fad with word processing where it matches paper shape better, but these days people tend to use multiple side-by-side windows on a big monitor. (And often multiple monitors too.) There are utilities that can force your graphics card to output non-standard resolutions; I imagine how well these work varies from card to card. (Note that in extreme cases this _could_ damage the monitor, though I think only for very old CRT ones - modern ones, including later CRT ones, usually detect "out-of-range" feeds, and pop up a notice to that effect on screen, or at least just go blank, or display an unlocked picture.) I'd say it's definitely worth investigating these avenues - conventional monitors (of the two shapes) used with unorthodox resolution settings, and the possibility of using them sideways. Agreed, check all avenues before choosing. I purchased a 24" Asus Pro-Art monitor. $369, shipped and sold by Amazon, for the Mac Mini. On my W7, W8, W10, Linux mint (KVM switched) is a Dell U2412M. Both are IPS panels, although I didn't know anything about the panel types when bought the Dell. Not quite as good, but it was cheaper. Input is display port, and based on limited options for testing HDMI input, I'd avoid that option if possible. VGA was OK, but I had no means to check DVI. Both have an aspect ration of 16:10. After 10+ years of the iMac with 16:10, I just don't want 16:9. Interesting. I wanted to go 27", but but couldn't find anything that fit my specs. 32" is what I really would have liked, but physical, available space prevented that. Could you rearrange your working environment so you could use wall-mounting (or on a pivot arm)? Assuming you can find an 8:5 32", that is. -- J. P. Gilliver.

When I was growing up, the "@" was also used to mean "about". I wonder if that has to do with the capabilties, or lack of, of typewriters. For the common computer monitor aspect ratios, don't forget 5:4. I actually have a monitor with that ratio. 1280 X 1024, SXGA. I found one other screen resolution with this ratio, 2560 X2048, QSHGA. When using the occasional laptop, I'll drag my 5:4 monitor out and use it. The number of aspect ratios I've found is 57. Some are really strange, and I've no idea where they are used. One works out to be 683:384. When I first started this investigation into making the screen easier to read, I was expecting to find some monitors to have a different sizes for the individual pixel. But apparently they don't, so I quit looking at that spec. [] I'd already learned some monitors cannot display light greys, light blues, and thin lines. Although the line issue may be tied to the color of the line. I don't know. I'd be surprised if any monitor _used at its native resolution_ can't display a one-pixel-wide line, unless as you say it's unable to distinguish the colour of the line from the surrounding area (in which case the thickness of the line wouldn't have much effect). I discovered all of this on websites, not with any programming on my part. And the width may not be of importance. There's an online maintenance management software called Podio. The program, when I was using it, used one of those light greys as a background. But they did not put any kind of border around the fields you needed to fill in. The monitor displayed the background as white, and the fill color of the fields was... you guessed it, white. LOL Made it hard to determine where the input field was! LOL One day, out of curiosity, I tilted the monitor top edge away from me to about a 40-45˚ angle, and there was the grey background. Not a practical solution, though. VBG I learned the best LCD panel for display of colors is an ISP type panel. So, that's what I bought. The best interpretation of that (to me it's "internet service provider"!) is "image signal processor". I'm dubious, but if that's what you've found ... Paul and nospam are correct, it should be IPS. Muscle memory, I guess, but at the same time, I don't see some letters that are "right in front of me". And in this case, spell checking may be useless. For instance, at the native resolution, maybe I don't see the letters "abcd". But if if I go to the next lower resolution with the same aspect ratio, it may be the only letters that are missing are "cd" due to the magnification effect. When I look at a vertical straight line, this is what I see: | \ | | / | More or less. LOL I experimented with the options of increasing the text size by 125% or 150%. Bit this does not change the size of the text in menus in the windows. And, if the situation is right, dialog boxes may have the buttons you need to click on off the screen to the bottom, and you can't get to them! All of this is just part of the reason I won't be using W10, and will stick to W7 when I use Windows. W7 gives me more options for correcting the screen display so I can see it. I don't think MS gives a damn. And boy, am I glad I did. I learned some monitors also cannot display light yellows! 0.

Agreed. Though intuitively using the wrong resolution seems very wrong, the blurring _can_ be not very noticeable - and, as you say, if you have some eyesight conditions it may be not noticeable at all. It took me a while to get past that mental impediment. But it's now my "new normal", and I don't even notice it unless I think about it. I think it helped when I viewed the situation as just looking at a smaller monitor through a full screen magnifying glass. I'd rather be able to read the screen with barely noticeable blurring, than fight with the recommended resolution to figure out what is on the screen. I find native resolution the best, if only for psychological reasons (if I "know" there's blurring due to using the wrong one, then I think I'll see it even if I can't really!).

Now, when I use a 16:9 screen, I find it feels "cramped". I immediately became a convert to the idea of "the more screen real estate, the better" when I went from a 14" to a 17" CRT monitor. I had a 19" Atari branded Moniterm B&W monitor attached to a TT030 computer, and simply loved it!! Gave the system away, and have regretted it ever since. I wanted to go 27", but but couldn't find anything that fit my specs. 32" is what I really would have liked, but physical, available space prevented that. Could you rearrange your working environment so you could use wall-mounting (or on a pivot arm)? Assuming you can find an 8:5 32", that is. My "main" systems are in computer desks with this design style: https://www.google.com/search?tbm=is...mg.3jCItgMUz-E Mine are much smaller in width that those shown. In one, 24" diagonal is all that will fit. In the other , 27" diagonal *might* fit, but I'm sure the physical vertical dimension would be an issue. But an IPS monitor seemed to be nonexistent in that size. And with anything wall mounted, what happens if you are renting an apartment, or selling your house?

When using the occasional laptop, I'll drag my 5:4 monitor out and use it. The number of aspect ratios I've found is 57. Some are really strange, and I've no idea where they are used. One works out to be 683:384. Do you _mean_ ratios or resolutions? There are a lot more resolutions than ratios. When I first started this investigation into making the screen easier to read, I was expecting to find some monitors to have a different sizes for the individual pixel. But apparently they don't, so I quit looking at that spec. They _do_ vary, but not as much as you'd think; at any one date, most of the panels on sale will have a similar pixel pitch, i. e. bigger panels have more pixels. Within a broad range, anyway; if you get into advertising panels, things are different, but those tend to be individual LEDs these days anyway. (And 'phones are different again.) If you don't have visual acuity (such as some eye problems), you _can_ sometimes find a big low-resolution panel (big pixels) at a low price - end of line, or of course second-hand. (I think I have a 20" 1024×768.) [] And the width may not be of importance. There's an online maintenance management software called Podio. The program, when I was using it, used one of those light greys as a background. But they did not put any kind of border around the fields you needed to fill in. The monitor displayed the background as white, and the fill color of the fields was... you guessed it, white. LOL Made it hard to determine where the input field was! LOL One day, out of curiosity, I tilted the monitor top edge away from me to about a 40-450 practical solution, though. VBG Ah, the infamous viewing angle problem! [] When I look at a vertical straight line, this is what I see: | \ | | / | More or less. LOL Oh dear! I don't think _any_ monitor (or playing with resolutions) will fix that )-:. I can't see how glasses will, either, unless your eyeballs don't move, to preserve alignment. I experimented with the options of increasing the text size by 125% or 150%. Bit this does not change the size of the text in menus in the windows. And, if the situation is right, dialog boxes may have the buttons you need to click on off the screen to the bottom, and you can't get to them! The text size manipulations aren't great - and many softwares don't honour them properly, so if you _do_ increase text size, they don't enlarge the box it goes in, so you end up with either overlapping letters, or text spilling out of the box )-:. All of this is just part of the reason I won't be using W10, and will stick to W7 when I use Windows. W7 gives me more options for correcting the screen display so I can see it. I don't think MS gives a damn. Worse: I don't think enough of them _know_ about these matters. There's _some_ attempt - I'd like to think it _is_ more than just "good PR" - to increase provision for disabilities, but I think such matters aren't matched by adequate programming knowledge. And certainly any such "standards" are hardly enforced at all when it comes to third party software. [] But the integral resolution may not exist. For instance, I've not found an example of 320 X 240. No, but - assuming you can set that as a resolution these days! (I thought 640×480 was the minimum for, maybe, Windows '9x, and that went up to 800×600 for, possibly, XP) - there would be no _blurring_ if viewed on a monitor of native resolution 640×480, or 1280×960; each 320×240 pixel would actually occupy a whole number of native pixels. (In these hypothetical examples, 2×2 or 4×4.) 1. Some modern monitors and graphics cards talk to each other, which might mean that the graphics card knows what shape the monitor is, and may refuse to offer "incorrect" resolutions. What's your definition of "incorrect" resolutions? Not mine, the hardware/firmware! I haven't really looked into it as tend to use native anyway, but I have encountered cases where I know the graphics card can offer some resolutions that Windows is not listing because it knows they don't suit a particular monitor - either because the user has told Windows what monitor they're using, or because the monitor has "told" Windows something about itself over plug-and-play. I wonder if those aren't the resolutions you see that are greyed out, when you move the slider in the resolution display. You might be right about the presentation (greyed out rows). I'll admit I haven't really looked at how the options are presented for an edition or two of Windows. I've just looked, and I see what you mean about a slider and greyed options on Windows 7. If magnification is something you need, you will want an alternative resolution that has the same aspect ratio as the native resolution. [] No distortion is one of my "specs". You want a square to be displayed as a square, not a rectangle. Mine too. When shortscreen displays first started to be the norm, though, I was amazed how many people accepted squashed displays - or, even, seemed not to notice that they _were_ squashed. It has improved of late as shortscreen has become the norm for both monitor and OS. [] This Pro-Art rotates 900 Or 8:5 (-: I think the need for rotating the monitor is generally limited. You're not going to gain anything visually from what I can see with my testing on this monitor. Instead of having 1920 X 1200, you have 1200 X 1920. If you have the form of astigmatism that _just_ makes you see the world with the wrong aspect ratio, it _could_ help. Depends on whether your distortion matches (in the other direction) one of the distortions available by playing with resolution settings, monitor rotation, and so on. I agree, though, monitor rotation is less used these days; it first became a fad with word processing where it matches paper shape better, but these days people tend to use multiple side-by-side windows on a big monitor. (And often multiple monitors too.) Even side by side isn't as good, especially for page layout in newspapers, or editing a widescreen photo where the camera has been turned 900 You won't change the shape now. Shortscreen came in, to a rough approximation, when someone in the marketing departments thought people were going to be watching movies on their computers, since movies had been shortscreen for some decades. It's _not_ ideal for most computer use; arguably it's not so bad now monitors are big enough to display two portrait windows side by side (though in practice lots of people still work maximised, i. e. the "two windows" argument doesn't wash), but that certainly wasn't the case when the shape change came in. (Even for movies, the shortscreen format isn't _that_ wonderful - fine for a row of "Injuns" on the horizon, or someone lying down; it was mainly introduced to be something different to TV. But that's history ...) So we're stuck with horizontal shortscreen, most of the time. [] Both have an aspect ration of 16:10. After 10+ years of the iMac with 16:10, I just don't want 16:9. Interesting. I found it amazing how much that extra vertical unit affects my enjoyment of what I'm doing. Now, when I use a 16:9 screen, I find it feels "cramped". See above re screen shapes. Though I've got used to having multiple windows open now, and might find it difficult to go back to 4:3; probably OK if it was the same _width_ (and resolution) as I'm used to. I immediately became a convert to the idea of "the more screen real estate, the better" when I went from a 14" to a 17" CRT monitor. I had Provided you've got room for it, bigger is always better! I have a big old laptop that has a 17" screen: it's rather underpowered for most purposes, but what I use it for - TeamViewer support of friends (especially blind ones; their description of what they "see" on the screen is often _very_ different to what I'd say!) - it's good. a 19" Atari branded Moniterm B&W monitor attached to a TT030 computer, and simply loved it!! Gave the system away, and have regretted it ever since. If we're talking CRT, B&W was always intrinsically higher resolution than colour. I wanted to go 27", but but couldn't find anything that fit my specs. 32" is what I really would have liked, but physical, available space prevented that. 32" CRTs were big, heavy beasts. Could you rearrange your working environment so you could use wall-mounting (or on a pivot arm)? Assuming you can find an 8:5 32", that is. My "main" systems are in computer desks with this design style: https://www.google.com/search?tbm=is...bih=919&ei=87Z 3XeyeJYHZ-gT2joGABw&q=computer+hutch+desk&oq=computer+hutch& gs_l=img.1.2 .0l4j0i5i30l2j0i8i30l4.587.2507..5237...0.0..0.89 .988.14......0....1..gw s-wiz-img.3jCItgMUz-E Mine are much smaller in width that those shown. In one, 24" diagonal is all that will fit. In the other , 27" diagonal *might* fit, but I'm Most of those still don't seem to have got to grips with the advantages of flat screen; they have a space into which the monitor is placed, still needing a stand and space all around, as if it was still a CRT monitor with bulk. None of them seem to have it attached to the back wall, let alone used lateral thinking and attached it as hinged _over_ some of the compartments thus allowing a bigger screen. sure the physical vertical dimension would be an issue. But an IPS monitor seemed to be nonexistent in that size. And with anything wall mounted, what happens if you are renting an apartment, or selling your house? G Good question! I suppose you could use a floor stand, but that'd have to be pretty heavy - or some sort of arm thing attached to the desk. -- J. P. Gilliver.

That should be screen resolutions is 57, and one of the resolutions works out to be an aspect ratio of 683:386. But I see Paul apparently figured out my mistake. When I first started this investigation into making the screen easier to read, I was expecting to find some monitors to have a different sizes for the individual pixel. But apparently they don't, so I quit looking at that spec. pixels do have different sizes, and by quite a bit, with hidpi displays having the smallest. It may be I gave up too soon. snip If magnification is something you need, you will want an alternative resolution that has the same aspect ratio as the native resolution. With the Windows units I've tested, dragging the resolution slider up and down will show multiple options, but only those resolutions that are listed when you are not dragging the slider have the same aspect ratio. Magnification _without_ *blurring* would need integral ratios. It is _possible_ that the integer could be different in the two dimensions, though I suspect the right ratios for that don't exist in practice. It's more likely, if you need magnification, that you won't see the blurring caused by a non-integral ratio, and as you say in that situation ensuring the same aspect ratio will give you magnification without *distortion*, which is probably more important. No distortion is one of my "specs". You want a square to be displayed as a square, not a rectangle. all lcds do that. As long as the screen resolution in use has an aspect ratio that is correct for the monitor in use. -- Ken MacOS 10.14.5 Firefox 67.0.4 Thunderbird 60.7 "My brain is like lightning, a quick flash and it's gone!" |
