Timing for a 3DFX Voodoo 3 at 1920x1080 (1080p)
Raw
voodoo3-1080p-60hz.md

Problem

3DFX Voodoo 3 running at 1080p has a black vertical bar at the left side of the display.

This happens regardless of whether connected directly to the display or using VGA to HDMI adapter.

Solution

Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\0000\TIMINGS (on win9x) or search registry for TIMINGS on win2k, it appears in several places or change the inf file before installing the driver

Change the timing string for 1920x1080 at 60 Hz to: 2200,2008,2052,1125,1084,1089,4,148500000,6000,8,30420

Calculated from instructions at https://www.vogons.org/viewtopic.php?t=59148 and timings at https://projectf.io/posts/video-timings-vga-720p-1080p/
