[Official] The Qnix/X-Star 1440p Monitor Club - Page 564

post #5631 of 25922
I've had this monitor for 3 months now I think. It was running fine until today as far as I can remember. I played around with multiple refresh rates, but at the time I noticed it I was at 100. I was also running one of the custom color profiles that boosted brightness. Only other thing to note is that i used electrical tape to seal the panel to help with black light bleed. However, that was done the day i got the monitor. I rebooted and the flicker seems to be gone not sure what could have caused that. Actually now that I think about it. I had a power outage earlier today for 30 seconds and everything shutdown suddenly. However, I have a high end APC battery backup unit protecting it. Not sure why it didnt keep the power on. Maybe the power shutting off like that damaged the unit, but I find that hard to believe.

So far I've turned off the color profile and turned off the overclock on the refresh rate. Hopefully this screen cleaner video fixes the issue. It's seemed to have already improved things.

The Screen Burn in Fix I found online seems to have fixed the issue for the most part. I will keep an eye on it.

I've read the extra input models have the addition of a controller board that greatly increases the response time? were you aware of that or is it not a big deal?
I want to use the monitor with my laptop, so i had no choice.

Weird thing is though it hasn't been marked as shipped on ebay, nor did i get any tracking... ordered 2 days ago.

Guys I have a very interesting problematic pixel. If you want to hear something really strange, you might want to read this. I honestly don't know what it is, and I can't really explain it well.

So I have this one pixel that is normally fine (displaying the color that it should be). Never noticed this until today. If I put any window around the area it's in, a green pixel appears. Take the window away, it disappears. And it gets even more specific than this. If I put the window below or to the sides of where the pixel is located, it won't show up. Only when the window is above the pixel in question will it appear. If I drag the window down so the pixel is in the window, it's still there, but it isn't green anymore. If I move a white folder window over it, it turns into a grey pixel with a slightly pinkish hue. But if I maximize that window, it vanishes (meaning it starts to work properly).

It gets even weirder. So I tried UDPixel just to see if I can make it go away. I put a window near it so I can find it, and put the UDpixel flashing square ontop of it. After some time when I noticed it was still there, I got rid of the window. I still noticed the pixel in the flashing square even with the window missing. I moved the flashing square away from the pixel and I can't see it. So I moved it back, and I can still see it in the square even when the window isn't there. Just has to be ontop of the pixel for me to see it.

Next, I went into a full white screen via UDPixel just to make sure I couldn't see it because of my black wallpaper. I positioned my eye directly over the pixel so I have it pinpointed, clicked to go into a white screen, and I couldn't find a stuck or dead pixel. I tried all different colors, and still couldn't see it.


So, tl:dr? This pixel turns green when I put a window near (specifically above) it on the desktop, but goes away if I move that window away. If I put the window over it, it looks like a dead pixel, but it isn't a full black, more like a grey. If I maximize the same window, I can't see the pixel anymore. I also cannot see this pixel when viewing the different color palettes in UDPixel.

This is very very strage. Any ideas?

Unless this is a bad sign for my QNIX, I won't be returning it to ipsledmonitors.com. I can only notice it under very specific circumstances. I didn't even notice it until today. Besides that, this monitor is near perfect. One permanently stuck (red pixel) in the bottom left corner (barely noticeable), and that's all the defects I can notice besides this pixel. Also, this monitor can overclock to 135hz without artifacts. I keep it at 120hz though.

Thanks guys!

I would recommend trying a different resolution (that your video card would scale) to see if it still happens to the same pixel, which would then actually be a subpixel of a larger scaled pixel. Also, try a bootable linux distro to see if other operating systems exhibit the same issue. Basically wondering if it's GPU/driver related...

Looks like it's the monitor, the exact same thing happens at a different resolution, and even in Fedora....

I just noticed something else. I don't think when a window (like a browser) is maximized it fully goes away. I can see the green pixel in the grey rectangle at the absolute bottom of this page, and if I scroll up into the white background, it turns to grey.

But wait it gets even weirder! I scrolled to the absolute bottom of this page, and went back into windowed mode (above the pixel), and the pixel turned to a faint green. If I scroll up (closer to the white), the pixel gets brighter green. The more I scroll down (to the darker color), it gets more faint. I'm just scrolling up and down repeatedly right now and the green is fluctuating in brightness.

So we have ourselves a pixel that responds differently to different variables, unlike a stuck pixel that is always static and one color, or a dead pixel that is always off. I have a green pixel that appears based on how I position a window on the desktop, changes in brightness based on the color of the window, and when the window is over it (maximized or not), it looks almost like a dead pixel on white backgrounds and green on darker ones.

I've never heard of something like this before. Have you? Any possible explanation as to why this is happening and if there's a way to fix it?

Upon inspection, I found a Fracture and Indentation about the size of Dollar Coin in the Screen.

I've notified Green-Sum about the Shipment Damage and filed a Shipment Damage report to DHL Canada.

I'm am waiting reply from the DHL Investigation Agent and Green-Sum as I type.

Wish me luck. I'm a Disabled Senior and have been saving for months to buy this Monitor.

Good luck, hope you get it sorted!

Why does green-sum drop the price when sales are up and supply is decreasing or at least constant? Doesn't seem to align with basic supply/demand microeconomics.

Only thing I can think of is it's a marketing ploy aimed to get more people to buy in a short period of time on gut decision... I guess money is the only thing that talks when your ad for the product is riddled with grammatical errors and reads like an unclear accent.

No gripes about the product itself though tongue.gif

I am having a little issue with my overclock. When my qnix is the only monitor connected it overclocks perfect, 120hz without and trouble. But when i connect my 60hz tn samsung as well, the overlock stop working. The refresh rate in nvidia control panel still says 120hz, but when i do the http://www.testufo.com/#test=frameskipping test, its only says 60hz (when qnix is the only monitor connected it says 120hz)

Any suggestions?
post #5638 of 25922
ok i got my qnix from green-sum, no dp, none to a very little backlight, i can oc it to 96 (didn't test 120 yet) because i can't figure out how to increase the resolution up to 2560*1440, stuck on 1080p......running win 8 im trying to put the monitor on test mode no luck...


edit...plasma tv connected to the hdmi port was sticking res to 1080p...now running 1440p 120hz stright 0 wrong thing...i have also a s27a950 , what can i say..wow..
