Quick overview:
If you have purchased a graphics card with the Kyro II chipset, such as the 3D Prophet 4500 from Hercules, the consistently good speed and quality of the card is marred by a bug in Windows 2000. In games and applications that work with Direct3D and OpenGL, the image flickers at a low 60Hz. This is particularly noticeable with bright colors. The eyes don't put up with this for long and start to water and burn.
Only from approx. 85Hz picture refresh rate does our eye no longer perceive flickering. It does not matter if you set the display properties for Windows to e.g. 100Hz at a resolution of 1024x786 - if you now go to 1024*786 in the game, you will still only have 60Hz because the settings (unlike in Windows 9x/Me) work separately from each other. To still achieve an ergonomic refresh rate, proceed as follows:
1. Click here to download the program KHzTool Now go to the directory and install the tool.
2. You can then easily set the refresh rate for each mode. However, I recommend taking a look at the monitor manual before setting too high a value here. This can damage it. To be on the safe side, you should first set everything to 85Hz
3. After you have restarted the program as requested, the eye-friendly values can be seen immediately.
Please only install the program with the latest driver version of your Kyro card.
