I have a Voodoo2 STB Blacl Magic PCI card (name it was listed as) plugged in with a PCI Diamond Stealth 3d card. I have them plugged up to a Sony Vivitron/Trinitron 1572 Gateway 2000 monitor. The monitor is bright and beautiful plugged into my 486 machine. To the point I had to turn brightness down to like 78 or so. On my Windows 98 machine with the above cards, the image is very dark. Even on the POST screen it looks much darker. What might cause this issue?
