No dead pixel (that I can see, but they are so small I might miss some).
A little backlight bleed on the top, but just visible in a dark room with full brightness.

Overclocked to 120hz on the first try.

Which color profile do you people use for qnix/x-star at 120hz?

I received my Pixel Perfect monitor from Accessorieswhole. It is pixel perfect indeed but it has blue and red tint that are visible on white backgrounds. Basically the colour temperature varies across the screen - the left part of it is visibly colder than the right part. The faulty panel that I sent back didn't seem to have that issue. Can any of you please check if white colour uniformity varies on your screens?

I mean this:

You can see a blue (8000K?) patch on the left side of the screen. It's difficult to take a good picture of it but it's very perceivable in reality. You can clearly see that there is some red tint to the whole screen except for that area and top right corner. The top right corner is not that bad though.

I tried several colour profiles but was not able to compensate for that blue patch.

Should I try to get a replacement of just live with it?

I already posted this in another thread but think it makes more sense to post it here.

Here are my 120hz and 96hz ICC profiles...i made these at a brightness of 200 cd/m which for the 120hz profile is about 18 clicks up from a black screen on the BRI+ button... and about 17 clicks up from a black screen for the 96hz icc profile

Nativedispcal120hz96hz200cdm.zip 13k .zip file

BTW: glad that you are happy with your monitor and welcome to the club thumb.gif

Are you only getting this when overclocked?...it is known that some people can have screen uniformity when overclocked which can normally be seen on a solid green background in the top right hand corner...some people have found that optimizing there timings and a change of cable has helped...also most have to look to find it and so therefore have decided to live with it...i can only see mine in a solid green background only at 120hz and really have to look hard for it...in normal use i never ever see it....however if you have this at 60hz it is for you to decide weather you can live with it of not...

Nope, I get that at 60Hz with every single colour profile that I could find.

The seller is trying to convince me that some uniformity problems are normal but this is a problem with tinting rather than uniformity. I was wondering if anyone else had it at default clocks. Also, the issue isn't more pronounced at 96Hz.

Not sure how I could work the timings to see if I could make it a bit better but surely this kind of problem shouldn't be visible at 60Hz, should it?

The timings should only apply if you are overclocked as in some cases screen uniformity can be seen when overclocked....however most do not have screen uniformity at 60hz...i would try a change of cable if i had one laying around...and if i felt i could not live with this screen uniformity then i would argue my point with the seller!... if you are not getting anywhere with the seller and you bought through Ebay you could consider opening a case with Ebay.

I don't really have to look for it. The blue tint is clearly visible if I open gmail with default colours or just go to Amazon website - the left part of the screen seems to be colder and blueish.

Already opened a case on eBay but the seller is trying to convince me this is normal.

I'll try a different cable today. Doubt it will help but it's always worth trying. Thanks a lot mate.

Was LOVING my Qnix 120hz monitor until I took it to a friends house who has a classic Yamakasi Catleap. The glossy screen on the Catleap make the black levels much deeper and the colors pop more. I am really debating what to do..

My Qnix overclocks perfectly to 120hz, no dead pixels, minimal lightbleed. Would that resell for much on eBay?

This morning, my DP2710 developed an issue:

I turned on my computer, and walked away to get breakfast. I came back and the screen was flickering. I think I had bumped my DVI connector, and it was loose (I switch it between two computers, so it gets moved back and forth daily).

I plug in the connector securely, and the right-side inner quadrant (one quarter of the screen top-to-bottom) of the screen is full of red and green vertical lines frown.gif

I've tried unplugging the monitor, plugging it into my other computer, and a different DVI cable and I still see the red/green line artifacts frown.gif Additionally, if I unplug the DVI entirely, and it goes into the default "show a bunch of colors in sequence" routine, it still shows it, so it's definitely not the cable.

For the hell of it, I tried overclocking it slightly at this point, to see if it was some sort of clock issue that could be resolved by changing it back and forth, but no luck... I hadn't overclocked it at all before this.

I've had the monitor for approximately 4 months, am I screwed?

Thanks.

EDIT: The lines have faded over the course of a couple of hours, hopefully will continue fading out back to normal again. Leaving the solution (just wait) here in case this helps someone.

Hard to say, shipping it might make you take a big hit.

Roger that -- I will have to look to see what my options are.

Has anyone tried the Yamakasi Sparta 300/301 30" or the latest AH-IPS 27" and how they compare to the Qnix?
