since i got my 2710 about 3 years ago i was initially able to hit 120 with no artifacting with a gtx 670 since then ive upgraded my gpu twice, and every time ive done that i have to lower my overclock to avoid artifacts...
i went from a 670 to a 970 and had to lower to 115hz now im using a 980ti and had to lower it again to 110hz and im still gettins the green lines.... whats the deal here?

*edit* ive even tried the "reduced" timings and it doesnt help
im using the toastyx patch and cru for this aswell.

heres a pic of my timings as of now, im not to good with this part of it http://i.imgur.com/IsGZrOK.png

so something went wrong with my qnix 2710 and i could smell smoke. this happened a week ago. i presumed something went wrong when my UPS did a test run and burnt something on the PCB. i took it apart and it seems the 18N20GH went bad. is it possible to solder a new one on? TBH i have no idea on what to do from here on out.

i found this on ebay which looks like i can replace the bad 18N20GH with. anyone know their stuff about this and can confirm?

and here is two pictures i took to see how bad the damage was. everything else looks fine.

If I were you, just buy a good 18N20GH and replace it, see what will happen.
OR you can just replace the whole PCB

Wait for more pros to come with some decent ideas

I am thinking to grab another qnix to pair with my current one.
How is there current quality? I say the price seems dropped a lot, quality drops together?

another concern is, I am current using an 7950, the DVI-D port is already taken
so this means I have to buy the second one with DP/HDMI port , or the DVI-I will work?

I've seen one with HDMI port, will this support 1440p resolution @ 60Hz, (won't try OC)
another one with both HDMI 1.4 and DP 1.2 will this one support 1440p resolution @ 60Hz?
price is only $10 difference.

advice appreciated.

What causes one of these monitors to cycle through full screen colors? Is it an input that's out of its range, or something else? What can I do to fix it?

hey guys,
does anyone have experience with the "accessorieswhole" shop on ebay with shipping to germany? i ordered a qnix from them on sunday with express delivery. but they still have not updated the ebay status to shipped?! is that common. i have an expected delivery of thursday (tomorrow) to tuesday. but i think a delivery this week is actually already out of questions since they didnt even start shipping it yet.

i know i am impatient :-) but it bugs me that i dont even have a trackign number or anything like that. rolleyes.gif

maybe anybody has experience with that and knows if its common that they dont update the ebay status or something like that.
thx in advance
greetings from germany

I already have one of the oldschool panels that overclocks to 120hz no problem .. question is: Can I grab two more of these and run NVidia surround in SLI? I also have two 970's. Is this possible with three DVI ports? Been getting more into sim racing and want to make a nice setup. Any help is appreciated, thanks.

Finally got mine from Accessorieswhole and this thing is amazing.
No dead pixels but has some backlight bleed in the bottom corners.

Already overclocked to 120hz and tested with phone camera and frame skip test. Looks like its not skipping or the phone is not fast enough picture taker.

But when at 120hz it feels so smooth biggrin.gif

EDIT: It does have some weird burn in issue. Some websites have burned into my monitor lol

EDIT2: the 120hz that was running fine on first day started artifacting on the second day. Feels bad man frown.gif

Just a warning to those of you thinking to overclock these monitors.

The n-mosfet referenced in doco's post above is not rated for what goes through these things when overclocking and the chances of it going are very high.

The same thing happened to mine some months back (I purchased late 2014 iirc) and I have spent the last couple of weeks scouring the web for as much info on them as I can get.

Unfortunately, when I tried to replace the FET I wound up frying the replacement. Thankfully I have a spare to try with (both rated slightly higher than the original), but I will need to do a little maintenance on the PCB as well in order to make sure the drain tab dissipates heat properly.

Once I get it working again, I don't plan on overclocking it anywhere past 75hz!
