hello all i recently changed the motherboard and im running into a black screen. i put in a geforce 4200ti but after i installed the via agp driver(from 4.35) and installed nvidia 45.23 i keep getting a black screen and it hangs. are there any drivers out there that are compatible with the nvidia 4200ti? I have tried it with a geforce 2 mx with same driver and apg driver. work without issues.
board is a p3v4x with a piii @933
Are you perhaps using the TI 4200's DVI output with a modern HDMI monitor that is capable of resolutions that exceed 162MHz bandwidth (the limit for single link DVI) and using the Geforce 2 MX over analogue VGA output?
I ask this because I had similar behavior on both an FX 5900 and an TI 4200 when using DVI output on modern monitors that have HDMI inputs and support higher resolutions than what the video card can output . I had to use an EDID emulator with custom resolutions programmed to work around this issue .
The reason I believe this happens is, IMHO, because of a bug/limitation in the Windows drivers for these cards . In a nutshell :
1) the cards support single link DVI which tops off at 1920x1200@60Hz (with reduced blanking) which requires 162MHz of bandwidth .
2) the monitor EDID exposes a native resolution/refresh rate combination that requires more than 162MHz (i.e. 4K, 1920x1080 at more than 60Hz, etc)
3) the Windows driver is programmed to default to monitor native resolution as read from EDID, but does not take into account that the monitor has a resolution that the video card simply cannot output over DVI and you end up with a black screen, no signal, out of range, etc
The EDID emulator workaround works because it exposes to the card/driver only resolutions that it can actually support over DVI .
For more details, see :
Re: 70Hz in pure DOS at 1600x1200 (or other) over DVI on an old card (FX5900) with modern monitor is possible
Re: Widescreen monitors and 4:3 aspect ratio compatibility thread
If this does scenario does not fit your use case/symptoms, my apologies, I was on a roll .
EDIT: If the TI 4200 was working with the same monitor before you changed the motherboard, the scenario described obviously does not apply .
