Yea me too. I just run it an 60Hz on the desktop and 96Hz in games.

Flashing the entire screen R-G-B can cause the weak pixels to get stuck, although you're bound to run into that sooner or later. So you might end up with more stuck pixels (prematurely).

No need for videos. Sometimes you're not even certain they run as fast as possible (at the refresh rate) to nudge that stuck pixel to finally move. They might jitter and miss frames so that makes them less effective.

Use UDPixel and set it to flash only the single pixel itself or a bunch of pixels including the stuck pixel. I remember using the first method and gave it a few hours. It removed a stuck pixel that appeared on my (then ~2-2.5 -year-old) ViewSonic VX2450wm-LED. The stuck pixel appeared a few days later then silently disappeared forever. It's been a few months.

So yes unsticking pixels can work but no need to flash the whole screen. Just flash the stuck pixel itself.

well no help here, but I solved it myself.

at first I thought it might be because I was using a program called ultramon (which is a dual screen display controller program) uninstalled it, no help.

so I went with my original hunch, qnix was plugged into gpu 2, monitor 1 was plugged into gpu 1. where as gpu 1 was the primary gpu for windows. I put the qnix on gpu1 and the other on gpu2 and some of the problems went away. put them both on gpu 2 and boom, works great now. oc'ed to 120 fine, started fine, but artifacts and studdering in game. set to 110 now and works the charm

Recommended to push your pixel clock down when you get close to 450MHz (110Hz+). That would lessen the overclocking side effects and allow you to run a higher refresh rate at the same pixel clock you are using now (I'm guessing 443MHz at 110Hz).

Just by tightening my timings according to Jerrold's post (I have an AMD GPU), I got 117Hz at 448MHz up from 110Hz at 443MHz. Gamma shift is the same and there are no uniformity issues (measured and verified).

If you have an Nvidia GPU search for Spartan F8's post "Front Porch".

Hi all
After lurking around this forum for years I decided to join.
I just recently bought 3 X-starDP2710LED from dream-seller to replace my old set of 24'' 1080p. They all look great and work as expected. However I ran into this small problem.

When I installed Linux on my computer, after installing the NVidia driver (I have 2 GTX 780) one of the monitors would not show any picture, instead it kept cycling through all the colors (white, red, green, blue, gray). If I plug in just that one monitor to one of the DVI ports and install the drivers, everything is fine. As soon as I plug in the other 2 monitors (one to the other DVI ports and one to the Displayport to Dual link DVI), then the same thing happen again. I tried with my AMD 7970 as well as several different Linux distros, same thing. The strange thing is everything works fine in Windows 8.

Does anyone have any hindsight? Thank you very much.

Great forum by the way.

Thanks for the answer! I have heard of UDPixel but haven't tried it yet. I'll try it once I get back from my trip.

This actually sounds safer to me. Thanks again! thumb.gif

Does anyone with a GTX 580 or any 5xx series card have a problem idling down even at less than 404mhz pixel clock speed? Its supposed to idle down at anything with 404mhz or less.

Im wondering if my GPU is shot or something, because I could have sworn it used to work and idle down at the 404mhz speed.

It still idles down at 60hz though, but anything above it does not.

I've read a few days ago an article concerning Nvidia's and AMD's shananigans concerning monitors. Nvidia seems to not allow 3 (or 3+) monitors from running in multi-monitor mode on Linux as that would be offering a similar experience to the Windows counterpart, or so I've read. Might want to find out more about some driver limitation along these lines.

@VENAXIS: Tell us how it goes, whether it removes the stuck pixel or not.

Hi yasamoka, thanks for the reply.
I was running 3 monitors with linux on my old Viewsonic 24'' just fine. This only happens with this new X-Star. When I unplug the troubled one and tried a different 24'' then everything works. So I have no idea why that one monitor would not work in Linux, in Windows it runs beautifully.

damn, recently i have ordered 7950 to update my rig.

i was considering a korean monitor one year ago, but my HD5850 was incompatible. now i really want it again...

what i'm scared of is lack of warranty (well, shipment to korea from poland must cost fortune. its 1 year only too) and potential issues with it (not overclockable to ~90-120hz or working badly in this speed, large bleeds, GPU not fast enough for 1440p)

how many buyers have reported their korean-monitor-deaths? i saw at least one on neogaf (after few months of use)
