LG Electronics UM95 acting up

[dvanbriesen]

Thanks in advance for any help. I am a freelancer and an hour ago accepted a new large project due in a few days and am desperate for any advice of what might be causing my new issue.

I purchased an LG UM95 34" ultra wide 3440x1440 monitor back in April. It's worked almost flawlessly until a few weeks ago. It would turn off for about 30 seconds then turn back on every now and then. I just restarted my computer, and now half the monitor is showing what almost looks like a test pattern. The other half works. I also use a regular 21" HD monitor along side the behemoth.

Initially I was thinking it might be my power supply acting up, but I'm starting to think it might be the graphics card? The monitor displays the windows loading screen just fine, and only goes to half-test-pattern when windows actually boots. And has otherwise worked without issue, so I was hoping that the monitor isn't the problem, and that it might be my undersized PSU, or an underpowered GPU for the display.

A quick rundown of my system:

- 450w power supply (3-4 years old) - it might even be a 420-430w?
- quadro K600 GPU (2.5 years old)
- Xeon E3-1220V3 (same age)
- 24 GB RAM
- ASRock Z87 Killer 1150 mono (wasn't my first choice but it was on sale at the time, and fit my need of 6 - sata 6gb/s ports)
- 4 SSD's
- Windows 10

Some of that info probably isn't needed, but I just wanted to provide as much as possible.

Thank you again for any advice!

Sorry for the quick follow up. I also tried to plug the monitor into a laptop and it worked perfectly again. Do these symptoms seem possible from a dying video card? If so, do you recommend a good card for my monitor(s) and doing rendering and 3d animation work for mechanical and architectural clients (revit, auto cad, 3ds max, etc)?

Thanks
