This happens when a panel is overclocked the easy way and all you do is set it to a higher frequency rather than optimizing the pixel clock. It will go away after a while because like iwasaperson said it is NOT burn in it is color retention.

Also this website works very well. And i suggest getting a quicker screensaver or screen timeout if you don't optimize it.

Interesting, some time ago when i posted about this no one knew how to fix this. How do you know what to set the pixel clock to?

Believe me, it is not dead/stuck pixels you should be afraid of. I got one at the top right corner and I can only see it when I test for faulty pixels with a white screen and I really have to make an effort too. So far I've only seen one guy who had a cloud of stuck pixels that would really be noticable in every day use.
The thing you have to be afraid of is BLB! I was unlucky as I got a screen that was pretty much unusable after nightfall as the biggets part of it was flooded with light. It was very nasty. The tape mod fixed most of it though. Anyway, I wouldn't waste my money on the scam that PIXEL PERFECT is, but rather write a personal message to the seller, telling him he'd get an extra 20 bucks if my screen had only minor BLB.

I know by reading the way i have learned a few things(sorry couldn't resist). There has been a good deal of material in this thread regarding this but it has been recent(maybe earlier than some time ago?). If you search "front porch" or "custom timings"there is a good deal of info regarding lowering the resulting side effects of overclocking and how to effectively lower the pixel clock to lighten these side effects in the thread now. Some good starting points would also be to search in the catleap thread, this thread and take a look at the CRU thread as well(since it is the primary and most effective tool for doing this).

Essentially you need to know what each monitor timing setting actually does and how it effects the overclock(mainly the total pixel count but other do apply). With this you can benchmark the pixel clock in a negative since gauging the resulting image stability using some of the several previously mentioned test tools(powerstrip, UFOtest, refreshrate multitool). This will help to lessen the overall stress of data going over the cable which is what causes overclock side effects in PLS panels(very probably all panels to a certain degree).

After knowing a bit of what you are doing it is very easy and only takes a little time and effort(unless you start trying different cables, ports, drivers, etc) and will result in significantly less predominant side effects(no more panel uniformity issues, color retention, flickering, the occasional green line)

So do a search, read, test and let us know how it turns out. thumb.gif

Does anyone have any opinion of this seller: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130922075493&ssPageName=ADME:X:RTQ:US:1123?

He hasn't sold many of these monitors, probably due to the price, but I contacted him, and his pixel perfect policy is truly a pixel perfect policy, not 0-2 but 0, at least in his own words. I'm very sensitive to stuff like dead or defective pixels, even if they are hardly noticeable, so I could pay premium to guarantee there aren't any.

Hi there, I have a question to ask.Is there a difference between X-Star DP2710 and Qnix QX2710? I can get the X-Star DP2710 at approximately 182.20 USD with 6 month warranty while the Qnix one at 345.60 USD. thanks for reply

First post in thread has all needed info.

Q: Should I buy an X-star or Qnix (Which one overclock better?)
A: Short answer: Choose whichever one you want.
Long answer: They have the same screen, (both samsung PLS), and look almost identical other than their logo. Neither one has been proven to be clearly better, at this time. The general consensus is believed that they have the same random OC-ability.

I'm very sensitive to stuff like dead or defective pixels, even if they are hardly noticeable, so I could pay premium to guarantee there aren't any.

I got mine from him. He ships pretty fast, I had mine within five workdays, so that's a plus. One stuck pixel in the upper right corner, which isn't bothering me (I purchased non-pixel perfect). I have to complain about the horrendous back light bleed though! If the tape mod hadn't fixed it (or most of it) I'd have sent the monitr back. It does say 100% tested on the ebay site and there was a letter inside the box from assecorieswhole, but, quite frankly, if a monitor with that amount of blb gets through "testing" I wouldn't give a crap on that garantuee.
That was just my personal experience though and probably some bad luck, generally I haven't read any complaints about him and he also responds very fast. I'd say, go for it, but save the money and don't go for pixel perfect.

edit: I got a x-star, but seeing as there are near to no differences between these two brands I think my input might still be relevant.

No. Every monitor has the possibility of having or developing dead or stuck pixels.

This is a question for people out there who like to wear their "tin foil hats".

It is widely rumored that Apple will be launching a 4k display alongside of their new Mac Pro this Fall 2013.

This display would still be some sort of IPS/PLS manufactured by either LG or Samsung, and I'm assuming the B grade panels would still be picked up by Korean vendors and turned into a new breed of 3840x2160 Qnix/X-Star/whatever monitors.

I'm just wondering if anyone has any idea how this might affect the price of these current 1440p monitors, and how much the rebranded 4k monitors might cost.

Obviously nobody can know for sure, but I'm interested in hearing people's opinions.
