Hi There !
I am facing a problem where monitor goes blurry after some time interval. The following are the machine details:
Dell Optiplex GX320
NEC LCD Monitor 92X
So far I have tried following things to fix this issue:
1. Tested three monitors of different make and model.
2. Updated display driver.
3. Updated BIOS.
4. Tried different resolution settings and monitor refresh frequencies.
5. Tried clear type setting. Restarted PC
6. Changed display cable and monitor power cable.
7. Dell changed motherboard Thrice.
8. Dell changed power supply and fans.
9. Changed power extension board.
10. Changed power socket.
11. Installed PCI-E Display Card.
After trying all the above steps I found the monitor gets blurry after working for a while. The only way to fix the problem is to restart pc couple of times or unplug monitor power cable and wait for few mins or let it fix itself.
It is getting very frustrated for user. So if anybody can help then it will be really appreciated.
Thanks a lot…
