after installing 2nd vga card on my system i lost display from 5850 only on 226BW.
After 3 day and after >50 combination of different hardware i found out that my xfx 5850 stopped displaying image only on my samsung 226bw.
The biggest mystery is that my notebook and two other vga cards can light up this lcd but xfx 5850 won't, not even on POST neither in linux.
When i boot win on my old crt i have normal picture on my xfx5850 but when i connect samsung 226bw i loose picture on crt and have no picture on samsung 226bw. WHEN I DISCONNECT 226BW PICTURE RETURNS ON CRT.
-my system and everything on stock
-5850 will not display anything on 226BW but can light up any other monitor in my house
-8600gts displays normally on 226BW and any other
-9600gt displays normally on 226BW and any other
- my notebook displays normally on 226BW and any other
-my system and everything on stock + old 17"CRT
-if i try to connect any other monitor in my house and extend desktop to it it work normally
-if i try just to plug in 226BW i loose picture on CRT, if i unplug it, picture returns
when i connect cable of the 226bw to xfx5850 i loose display on crt and no display on 226bw , BUT if i jerk around that cable on the dvi connector on my card, strangely 226bw starts to work and in some circumstances even crt displays image. I have tried with several different cables
