I have a problem changing the resolution on my monitor from 640X480 to
1024X768. The monitor supports the latter as its maximum resolution. if I
select it either on the fly or change it and reboot I get flickering
horizontal bands of colour and have to reset it to 640X480.


I have the following:
SBM 14" svga monitor (not DPMS or PnP)
Tseng ET-6000 PCI VGA 2.3 meg colour card.


I do not have enough technical experience to know for certain but I suspect
that the graphics card does not have enough ram to enable it to switch to
the higher resolution. Is this correct? If not, how much ram does it take to
support this mode?


I know for a fact that the Tseng Labs ET-6000 will do 1024 because I had an
STB Lightspeed 128 with that same exact chipset, and I used to run that
resolution. It is possible.

More likely, the ET-6000 is trying to run 1024x768 at 60hz, whereas your
monitor might expect something weird like 56hz. I had an old 14" magitronic
monitor that could do 1024x768 at 256 colors, but only at 56 hz, which most
video cards don't have as a standard option. Couple that with no win95
driver for my monitor, and it was a mess.

BTW, for future reference, the driver for the ET6000 provided on the win95
setup disk works just fine for most cards using that chipset, so if you ever
need to re-install windows (who hasn't) then don't worry about fishing for
that new driver, just use the stock windows et6000 driver.
