For the last 3 years i have worked with Windows XP , 2x Sapphire Radeon HD 3850 512 MB videocards and 3 monitors connected (2x 22inch and 1x 19inch).
This worked without a single problem.
Since i got a terrible virus i was forced to upgrade to Windows 7.
And from this moment the problems started.
Only 1 22 inch monitor displays the correct resolution 1680x1050. The other 22inch is set to a lower resolution and when i manually try to set it higher it wont go to the desired resolution.
In the mean time i have removed the 3rd monitor. So currently i am working with the 2x 22inch.
I have tried to install every single driver
available but nothing works.
The funny thing is that when i installed windows 7 that the monitors did work for about 3days. Suddenly the monitor resolution changed and i couldnt got it back.
1 time when trying installing older drivers
the monitors went back to the good resolution but with in a day it failed again. Now after 2 weeks of trying and installing /deleting drivers i have no idea what to do anymore.
My PC details:
Windows 7 Home premium 64bit
Quad Core Q6600 2.40 GHz
4GB RAM memory
Gigabyte GA-P35-D34 rev. 2.1 motherboard
2x Sapphire Radeon HD 3850 512mb PCI-e videocards
(I am using ultramon for multiple taskbar)(but after removing it the problems still exist)
Can someone help me ?
