ET4000 Windows refresh rate

Postby dosfriend » 2016-12-05 @ 07:51

Just put a new card on my 5x86 rig: Hercules Dynamite VLB 2MB, which uses a TSENG ET4000 chip.
I was wondering if there is a way to increase the monitor refresh rate on Win3.x, since I can't find the option.

Now is set at 800x600 @60Hz which is a bit annoying (my monitor supports up to 150Hz on this mode).

Thanks!

I think you have to use a DOS utility to do it. It might be called something like setres, and it's not very user friendly.

Tseng uses vmode program for video refresh settings. But I don't use it as I use only LCD monitors.

Was able to set refresh rate to 90Hz for DOS games using SETCRT Hercules util, but sadly that doesn't change it for windows.

At least with my dynamite power, I had to use a DOS utility to set the windows refresh rate.

I couldn't find any Windows or DOS utility to set this, but finally I was able to increase the refresh rate up to 100Hz, and now I'm using VESA 72Hz.

Just add this to system.ini file (800x600@72Hz):

[Hercules]
fsResource=off
fsResolution=off
DISPMODE=800,600,8,800,600
BigMap=0
pd_runm=0
DM1=800,600,8,800,600,0
DM0=800,600,8,800,600,0

[Tseng]
DisplayInf=OEM0.INF
DisplayIndex=3
refresh800=72
;refresh800=100
frequency=2
resolution=800x600
colordepth=8
fontsize=small
