[comp.sys.ibm.pc.hardware] Problems with SVGA 800x600

msschaa@cs.vu.nl (Schaap MS) (02/28/91)

I have bought a NEC MultiSync 2A monitor, but my VGA card
has some trouble with 800x600 modes.

It is a Tseng ET3000 based card with 512K, 8 bits
(a Puretek VGA Ultra) which seems to be Orchid Pro Designer
compatible.

When I put my monitor in 800x600, either 16 or 256 colors,
the monitor clicks and gives a faded, horizontally shrunk
image.

When I load the BIOS into RAM (the TurboVGA.COM program),
800x600x16 works, but still clicks.

The BIOS version is 8.00, both ROM and RAM.

Is there anything I can do to make it work? Perhaps a new
BIOS version? Would it be legal if someone sent me one?

Can the monitor be damaged by using 800x600 modes anyway?


Thanks in advance,

Hi there,
That click you keep hearing, is yer NEC multisync switching
from one mode to another (I reckon it has to to some fancy 
stuff in 800x600 modes). So this click is absolutely normal!
It doesn't harm yer monitor (that is even after years of
work in 800x600, the NEC still works perfectly ok) because
this is how it should work!

So don't bother about this...
