Qnix QX2710 vertical gray bar in 120hz?

post #1 of 8
Thread Starter 
I just got the monitor last night from greensum. It's great, no dead pixels, some black light bleeding, but it doesn't bother me at the moment. However today, I tried to see what gaming at 120hz was like, so I did everything in the overclocking guide. Worked great, except while on the desktop I notice a long thin (about 20 pixels wide) gray bar almost had the look of image retention I see on my plasma TV or old Dell IPS.

When I revert back to 60 hz it goes away immediately; go back to 120hz it's back instantly. Am I going to damage the monitor gaming at 120hz and then switching back to 60hz when I'm done? Will this gray bar start to become permanent if I do? 96hz produces the same bar, but not as dark.

Try using a different cable. Also try adjusting your pixel clock timings. Really this needs to go into the Qnix club thread since you will get many more people to help there.

If it goes away with another cable or is at least less predominant then you know it is at least partially connection. You may also want to try a different port on your video card and see if it is still there. Lastly try drivers updates as they can offer greater stability.

Adjust my pixel timings to what setting? I don't own another cable. Tried the other video card output, same problem. Drivers already were updated in order to apply the overclock.

I would try say 100Hz and see if that gives you a grey bar? If not, you're still doing well with 100Hz

I don't think we're talking about the same thing. I already have tried 96hz as mentioned in OP and it's the same, just not as prominent.

I suggest sending the picture to your ebay seller to have him exchange it, but don't tell him that this only happens when you overclock.

Bad idea. Seller may pay the hefty return shipping, and upon inspection (with their 60hz configured pc) they won't notice any bar, get angry and tell you that if you want the monitor back, you need to pay the shipping back to your place, which will cost you $100 and a lot of wasted time.

They aren't really under any obligation to make sure your monitor works flawlessly at 120hz, remember these monitors were never designed to run at that refresh rate. If nothing works, such as changing the cable or other fixes suggested here, you can try sending the seller pics and getting a partial refund, but even then that's borderline theft and somewhat dishonest.

Best of luck!

Pretty much my thoughts exactly. If it were walmart, I'd do it in a heartbeat - but not to an ebay seller.

I'm not so much concerned about fixing it (as it does go away @60hz). I just want to know whether overclocking only for gaming (3-4 hours per day lets say) with or without this gray bar artifact could potentially damage the monitor in the long run. I don't want to severely reduce the lifespan of it.
