Can't specify display refresh rate
Hello, everyone.
For some reason I've been unable to specify a refresh rate value for a monitor connected to a PC running Windows 98. The setting I'm referring to is located under Start Settings Display Properties Settings Advanced Adapter. In the Adapter tab, there is a drop-down list which consists of a series of available refresh rate modes to choose from. Well -- it usually does. The problem here is that the list is empty. Apart from "Adapter default" and "Optimal" (both of which essentially mean 60 Hz), there are no other values. The system is equipped with the latest display driver for its graphics chip (S3 Graphics ProSavageDDR), and the monitor is installed as a Plug & Play device. It's a 17" CRT monitor capable of operating in high resolution modes such as 1280x960. I don't know how to convince Windows to populate the list of refresh rate modes. Is there anything to try before purchasing new hardware? Thanks |

Try this:
1. Change your display adapter to Standard VGA. 2. Uninstall Display Adapter software, if any. Not all adapters have this, but it's much more common now than it used to be. Look in Add/Remove Programs for any such thing. 3. Run MSCONFIG from the Start\Run menu, click on Advanced button at lower right, and "Enable Startup Menu". You'll want to restart and go into Safe Mode, and this makes sure the menu comes up, so that you don't inadvertently restart in Normal Mode. 4. Restart and go into Safe Mode. 5. Go into Device Manager and remove the monitor (or all monitors if more than one is listed.) Also look around for duplicated entries, anywhere in the list. Write down all duplicates. They have to be *exact* duplicates. Just write down what they are and how many of each. Lastly, if you know your system well enough, look for entries that belong to devices that were once installed but have since been removed. Remove any such entries. 6. Restart. 7. Reinstall proper Display drivers and/or accompanying software. If the problem seems to have started around the time you last updated the drivers, consider using the older version. Just because the drivers are the latest doesn't mean they're right for you, especially since you're running an older OS. Any tweaks in drivers these days aren't probably intended for Win9x issues. -- Gary S.

Thanks, Gary, for your insightful reply.
I followed your suggestion twice (each time installing a different version of the same driver), to no avail. While in the Device Manager tab, I noticed the following duplicates: Universal Serial Bus Controllers: USB Root Hub (3) VIA Tech 3038 PCI to USB Universal Host Controller (3) System Devices: Motherboard Resources (2) ACPI IRQ Holder for PCI IRQ Steering (8 -- I think it was present only in Safe Mode). Network Adapters: Dial-Up Adapter (2) (There were only one monitor and only one display adapter in the list.) In addition, I thought I would add the follwing notes: - At some point I noticed that the BIOS option "PnP OS Installed" was set to "No." I changed it to "Yes," saved the changes, and repeated your suggestion (for the third time). As disappointing as it may sound, it did not make any change, and the monitor yet refused to reveal its refresh rate modes to Windows. - At some point I also booted to Safe Mode, removed the monitor, and restarted with a different CRT monitor (which, I know for certain, can do better than 60 Hz) plugged in. Even this attempt failed, and Windows did not update the list of refresh rate modes. - It's interesting to mention that in all of the above cases, Windows always detected the plugged monitor as "Default VGA," and not as a "Plug & Play." It seems it's one of those unlucky cases, but if you think anything else can help (perhaps removal of those duplicate entries, or changes to the BIOS), please let me know. And thanks again for your detailed reply above. |

All of those duplicate entries are normal except the Dial-Up Networking
one. Not that it probably has anything to do with your problem, but I'd uninstall all networking components and reinstall. Unfortunately, I'm at the end of my list for the problem you're having. That the monitor is not being properly detected is worrisome. Did you try uninstalling and reinstalling the monitor *after* installing one or another of your video drivers sets? In other words, without also reinstalling the video adapter? At this point I'd probably be trying a different monitor and/or video card, but that's expensive if you don't already have those items available. Only other thing I can think of (besides the obvious checking of connections, reseating video card, etc.) is that a Registry entry may be fouling things up. I'll review the literature, but I don't hold out much hope if someone here doesn't recognize the issue. Not an easy issue to search on. -- Gary S.

A fellow MVP suggests that some monitors require that you have a color
profile assigned in order to be fully functional. It also occurs to me that you can manually install the monitor with the proper drivers (and color profile, probably) if you know the brand and model number and can find drivers for it. What Make/Model is it? -- Gary S. Terhune MS MVP Shell/User http://www.grystmill.com/articles/cleanboot.htm http://www.grystmill.com/articles/security.htm "David" wrote in message oups.com...

Hi again,
Did you try uninstalling and reinstalling the monitor *after* installing one or another of your video drivers sets? In other words, without also reinstalling the video adapter? Yeah, done that several times. In all cases Windows popped up a "New Hardware Found" dialog and initially identified the screen as an "Unknown device." A few moments later, the text was changed to "Default VGA Screen," the dialog disappreated and Windows continued to load normally. At this point I'd probably be trying a different monitor and/or video card, but that's expensive if you don't already have those items available. I tried a different monitor (with no better results). If I find a video card, I will try it too. Only other thing I can think of (besides the obvious checking of connections, reseating video card, etc.) seems to be alright is that a Registry entry may be fouling things up. I'll run MS Regclean, but my guess is that if it's a Registry-related issue, only Windows reinstallation can help. --- A fellow MVP suggests that some monitors require that you have a color profile assigned in order to be fully functional. By default there was no profile. I assigned one from %WINDIR%\System\COLOR but it didn't seem to affect anything. It also occurs to me that you can manually install the monitor with the proper drivers (and color profile, probably) if you know the brand and model number and can find drivers for it. What Make/Model is it? The User's Guide cover says "Newron 17" High Res flat monitor model no. F7U755". Thankgs guys for your help so far. I will do some more tests and will try to contact the monitor's vendor. If there is anything interesting to add I will let you know. |

If I find a video card, I will try it too. Well, if you tried another monitor, and it also came up bad, I think we can afford to assume it's the video adapter or drivers installation issue (such as the Registry problem I mentioned earlier.) Only other thing I can think of (besides the obvious checking of connections, reseating video card, etc.) seems to be alright is that a Registry entry may be fouling things up. I'll run MS Regclean, but my guess is that if it's a Registry-related issue, only Windows reinstallation can help. I doubt that RegClean will find this kind of entry, but it's worth a try. The kidn of thing I'm thinking of is an entry that acts as sort of a circuit-breaker when something goes haywire. Similar to NOIDE sometimes getting set in response to certain configurations, preventing the system from operating in Virtual Mode. I was hoping a reinstallation of the devices would prompt whatever it is to get removed, overwritten, etc. And it's way too early in the game to be thinking reinstall. It seldom solves the problem you're trying to solve, and it may make hash of your system, resulting in DLL Hell, broken patches, etc. Only as a last resort will I overinstall any Windows system, and then it's usually only when it's impossible to get into the system at all, and usually with the understanding that a completely fresh, clean install to a reformatted drive will follow soon afterwards. A fellow MVP suggests that some monitors require that you have a color profile assigned in order to be fully functional. By default there was no profile. I assigned one from %WINDIR%\System\COLOR but it didn't seem to affect anything. OK, that's one more thing we can probably cross off the list. Or it may require a particular one. Not sure on that. Did you restart after applying the color profile? It also occurs to me that you can manually install the monitor with the proper drivers (and color profile, probably) if you know the brand and model number and can find drivers for it. What Make/Model is it? The User's Guide cover says "Newron 17" High Res flat monitor model no. F7U755". Darn! It would appear that it's actually manufactured by a Korean company named Orion, which doesn't provide any support at their site. Only computer-related company named Newron that is likely is to be the one is an Israeli company that either doesn't have a site or the site has disappeared. Not a good sign. Can't find any drivers anywhere. Thankgs guys for your help so far. I will do some more tests and will try to contact the monitor's vendor. I'll continue the quest for an answer. I hope you can find the vendor. I kinda doubt, now, that the monitor is the problem, but you never know. -- Gary S.

Hey, a point of order, here. Everything I see says that a "Default VGA"
driver is a video driver, not a monitor designation. Can you confirm that the *monitor* is listed as a "Default VGA" in Device Manager? -- Gary S.
