I'm having problems with my 7850 GPU and I'm not sure what to do.

Digital output on my 7850 is not working anymore. I have tried DVI and HDMI. I'm currently using a VGA to DVI adapter and using my card on my current VGA only monitor.

Before this problem had occurred, I was able to output display to my TV using a HDMI cable and a HDMI to DVI cable. Now when I do it, nothing it picked up by my TV and CCC nor Windows can detect my TV as a first display or a second display. Also my current VGA monitor was able to be detected by Windows and CCC before the problem and now it is detected as a 'Generic Non-PnP Monitor' and 'Unknown' by them. The resolution was also set to a max of 1600*1200 and I had to manually change it to CCC to my monitors native 1920*1080.

The problem fixed itself yesterday and now it is back. I want to fix this problem before buying myself a new monitor.

My DVI and HDMI cables are working fine because they are working when connected to my iGPU

Things I have tried doing to solve this:

Reinstalling Windows 7
Running atiman uninstaller twice before installing latest drivers
Using beta drivers
Reseating the GPU
Placing the GPU in a different PCI-E slot

Here are my specs

Intel i5 3450
ASRock B75 Pro3-M
2 x Kingston HyperX Beast 4gb
1 x Corsair Vengeance 4gb
VTX3D Radeon HD 7850
Kingston HyperX 3K 120gb SSD
Xigmatek 600w

Monitor - Compaq Q2159

Please help me fix this

Thank you

I am thinking, as it occurs with each monitor a issue, reinstalling the latest drivers and a clean Windows 7 didn't change anything but you have NO issue with your iGPU, that the problem is the card itself failing.

The only other thing I could think to 'test' is boot to BIOS and deactivate the iGPU, set the PCI-E as the default display, then reboot and see if the issue resolves. Could be the video was gettign confused on which it was supposed to display through, but I am more inclined to think the card is failing /defective. Best test would be to take the card to another computer with the 'good DVI' cable you know works on the iGPU, and see if the card repeats the problem with the secodn system to a TV/LCD.

Deactivated the iGPU but the problem still occurs :( 

Does this mean the card is defective?

Note my other step to confirm defective card, test card in seperate system (friends, neighbors, etc.). Does it produce the SAME results no matter the computer, if YES then yes the card is proven defective /damaged.

Just tried it in my old Q8300 rig and the problem still persists.

Will I need to buy a new graphics card? RMA is a viable option with VTX3D

Unless you static charged it / otherwise broke it you could contact for RMA. The steps, including using it in another computer were the test. Also you did make sure both computers PSU had enough power to power ALL the components PLUS this card right? Card won't "work" if there isn't enough power.

Sorry I meant to type that RMA isn't an option because VTX3D's RMA centre is in Taiwan and insured whipping would be too expensive.

Both PSUs have enough for the system and the card.

If I was to buy another 7850, would I be able to CF with this 'broken' one? Games are working as usual on my current one, just digital output doesn't work.

CF??? not sure what you mean by that.

Think of it like figuring out the reason your tire keeps going flat is because you finally found the tear (not hole) in the tire. Your choices are deal with it as is or replace the tire. So if you keep putting air in it does that mean that is all that you need to 'patch' it with? or will it suddenly as your driving fall completely apart causing a major blow out and then subsequently a crash? Your guess is good as mine, but you know the likelihood of it getting worse is HIGHER and the RISK is higher that something will PROBABLY go bad to worse.

Crossfire. Shall I purchase a 7870XT/7950 instead? Or shall I wait for the 9000 series?

You could just wait, makes more sense, as we enter the School - Black Friday - Holiday season, you probably will see a sale come out on the 9000 series (might be packaged with BF4 or such). Personally I gave up on AMD/ATI for Nvidia because I like the 120Hz LCD I have and ATI/AMD doesn't support anything over 60Hz (yet at CostCo I saw the beautiful 60" 240HZ playing and OMG!!!!! how it looked!!)

Oh and FYI because your running a i5 there is a limitation point you will hit, weather you go single card, CF, etc. or not, because the i5 does have a cap on what it can support as compared to a i7 (seen the charts with the same systems different CPUs and was surprised). So keep that in mind to as you decide what to do.

wow digital output is suddenly working again on my card.

I put in a DVI to HDMI cable from my GPU into my TV and now its working fine and both my TV and monitor are recognised by my graphics card.

I'm not sure if my gpu needs replacing tho
