I need some help regards problem with monitor display blinking and then going blank after initial start up screen when using kvm switch between two computers. Both computers have CRT monitors (Samsung and Fujitsu). The kvm switches are the VGA/PS2 types.
Computer 1 is a Pentium 4 with a Gigabyte P4P800-E Deluxe mobo and 1.5GB RAM, Nvidia GeForce FX5200 + XP Pro.
Computer 2 is Duo Core (Conroe 6300) with ASRock 775Dual-VSTA mobo and 2GB RAM, NVidia MX440 + XP Pro
Have tried two different kvm switches (Laser & Wise - in Australia - did not find much info on net about them).
Both kvm switches worked okay when initially set up but on rebooting the P4, the Duo PC monitor only displayed up to Windows Logo, then went blank/power indicator blinking. Unable to reboot Duo PC normally,had to use VGA in start up mode. Finally had to reinstall drivers (i.e. uninstalled display drivers on/then reinstalled after bootup).
This also happened a few months back but at that time the P4 had an Nvidia MX400A card. Had same blinking monitor/blank screen issue - but on the P4 at that time. NVidia MX400 actually died on me, so replaced it with Nvidia FX5200.
Now it's the Duo with NVidia MX440 card with blinking monitor/blank screen, etc. But at least graphics is still alive.
Have tried Googling on problems with NVidia graphics cards/KVM switches. Seems there might be issues with NVidia but I'm not knowledgeable enough to undertand just what that is. Am wondering if next step might be to use ATI Radeon cards rather than Nvidia? (I do use Photoshop occasionally).
If anyone can help I'd be very grateful.
