If the problem persists when you connect the monitor to another system then
the problem is with the hardware and the only practicable solution is likely
to be a new monitor. You can try seeing if you can realign the colours using
the monitors adjustments (if any) but IMO the cost of a repair is likely to
cost far more than a replacement. If the monitor is still covered by warranty
you should contact Dell.

My Dell E771P monitor has red and green colouring at the bottom of
the screen permanently and won't change if I put it onto a new
system. Do you know if there is anything I can do? Thanks in advance
