Repair QNIX monitor, odd problem.

post #1 of 7
Thread Starter 
Long time lurker here, just registered smile.gif. I ordered a QNIX monitor from Korea a month ago and it worked beautifully for a week but it stopped working properly. Monitor seems fine when booting; POST looks clear as well as the OS loading screen. It works fine in a linux terminal, but when I get into the desktop I just get vertical colored lines everywhere, no image. As soon as I switch to terminal it works again. I tried changing resolution, refresh rate and power cable (not the adapter) to no avail. I opened the monitor looking for lose connections but everything seems fine. The only thing left to try I guess it's a new adapter, but I'm not sure that's the issue given that it works on boot and in terminal. Anyone with a similar experience? Any ideas how can I fix it?

This happened to me, what I ended up doing was taking out my 7950 gpu and putting in my friends 660 ti, then did driver sweeper a few times, then put my 7950 back in and reinstalled drivers fresh, worked fine. and yea use DVI-D cables only.

Forgot to mention I tried new DVI-D cables as well, I've an ASUS PB278Q so I tested all new parts there and they work.

My 460gtx worked fine with the QNIX when it worked, and it works with my ASUS. Also, I tried Ubuntu and Windows so I don't think it's a driver issue...

This Korean monitors are hit or miss, I know 2-3 people who have been screwed over with a bad one. You may just be out of luck. I have had mine for 2 months now, and I hit the power button this morning and it took it like 30 seconds to pop up... scared the **** out of me. lol


Lesson learned = stop buying ripoff brands and pay the premium with extended warranty.

Or get the QNIX Q2710 via Amazon and/or get a SquareTrade warranty.

Buying the same Korean monitor that way, gives you a far easier warranty.
These vendors take over the warranty hassle for you.

+1 anyone who can get a ST warranty should. It is a 300 dollar monitor that has the potential quality of a 1000 dollar monitor you can afford to bit the bullet on 35-50 bucks to ensure it.
