Hi all, been a long time reader and have got lots of valuable info from this great site, I have always been able to get PC problems resolved by searching this or other PC related sites, however I have been trying to fix this issue for several weeks now and can not come up with a solution, so I will get straight to the point.
I recently bought an AOC 2436vwh monitor, I have two PC's connected to it, the one connected via analogue runs fine, however with the other one using a DVI-->HDMI cable(monitor has no DVI input) I have not been able to get it to run at the full resolution of 1920x1080.
At first I had a Radeon 9250 video card, after doing some googling it became apparent this card was not capable of 1920x1080 resolution via the DVI output.
So I picked up a Nvidia 7600gs 256mb agp card(nice and cheap from ebay), this should be able to run the monitor at 1920x1080 from the DVI connection?
However I have still been unable to get it to run at 1920x1080 over the DVI connection.
I can get the desktop set to 1920x1080 but as soon as I do anything the image on the monitor starts to drop in & out, I have tried different settings, different driver versions and even powerstrip at the suggestion of a friend, but I still can't get it to run stable at anything above 1440x900 resolution.
The PC using the DVI-->HDMI connection details are:
CPU - Intel P4 524 3.06GHz socket 775 - 533MHz fsb
m/board - Gigabyte GA-81848p775 intel 848p chipset
Video card - Nvidia 256mb 7600gs AGP card
Ram - 1Gb - 2 X 512 DDR400
OS - XP pro SP3 fully updated
Is the above motherboard/cpu combo not capable of supporting this monitor at 1920x1080 from a DVI connection?
I have the seperate power connector on the video card plugged in and it seems to be getting enough power as I don't get any warnings re low power(I read about when this researching video cards)
The ratings for the power supply are:
+3.3v = 30A
+5v = 35A
+12v = 16A
Is this enough power for this system? I also have 3 hard drives and DVD burner in the PC.
FYI if I have the monitor set as the primary monitor(or the only monitor connected) I don't see anything onscreen until the windows log on screen, I don't see any of the boot up screens no matter what resolution I set the monitor to.
The second PC i have is:
CPU - Intel P4 northwood 2.6GHz socket 478 - 800MHz fsb
m/board - Intel s875wp1 intel 875p chipset
video card - Nvidia FX5200
Ram - 2 Gb - 4 x 512 DDR400
OS - XP pro SP3 fully updated
Would I be better of putting the Nvidia 7600gs into this second PC?
Would it be able to run the monitor at 1920x1080 via DVI if the problem is the other motherboard/cpu combo?
I would have tried it in this PC however I would have to swap power supplies around or get a new one as the one in this PC has only 10A on the 12v rail, I assume this would not be enough for the 7600gs.
Or do I need to do a complete upgrade to support this monitor at 1920x1080 via DVI or HDMI output?
I don't do any gaming, the PC's are used for general use, and basic graphics/charting programs.
Thanks for any help you are able to provide.
p.s I hope this is the right section!

Could you possibly hook the DVI-HDMI adapter up to another computer that you know is working fine? I suspect that adapter may be to blame, but I have nothing concrete to back that up, just something to check and eliminate from possible causes.
Ok I went and got a DVI to HDMI adapter plug today and used one of the HDMI cables I have in my HT set-up that I know can support 1080p.
Hooked it all up turned the PC on and the boot up screens popped up on the monitor, a good sign as these were not showing with the other cable.
I booted the PC, changed the settings from 1440x900 to 1920x1080, desktop comes up no problems so far, I open firefox browse to a couple of sites still not a problem everything working well.
I then started up powerDVD and started watching a DVD again not a single problem.
Have been running for about an hour now with the resolution set to 1920x1080 and everything seems fine.
So it definitely was the DVI-->HDMI cable that I had that could not support 1920x1080 resolution
Thanks for your assistance, it is greatly appreciated.
Now I can get rid of the second monitor and get my desk cleaned up lol
