[Official] The Qnix/X-Star 1440p Monitor Club - Page 48

post #471 of 25905
Nvm. Got mine in 2 days. OCes to 115, havent tried any higher. Some backlight bleed but not too bad. Only at the top. No dead/stuck pixels. Popped it open to remove the stand to VESA mount it.

Great purchase.

Another seemingly immaculate one from hulustar! No pixel probs at all as far as I can tell after 5 minutes and moving various images around the screen. Twice i thought I might have seen one but it was a speck of something. biggrin.gif Barely any bleed either (a very light thin line top right I think; might not have noticed if not for this thread). I am not quite sure what people are doing/using for the dark test but I have a solid black background plus transparent taskbar and the bottom and other corners are as black as the middle.

Like the stand fine except I think I will have to lean it forward; don't like display titled back away from me. Also I appreciate the inputs being on the side as opposed to the bottom for easier access.

Even if it's a dud overclocker somehow I am stoked for this price.

I had burn in at 60 Hz and at 96 Hz. The Macbook Pro Retina screens have burn in aswell and the original Samsung one has aswell since it uses the same panel.

We're not pumping twice as many electrons through the monitor. The more current flows, the more electrons flow through the cable.
And increasing the frequency will most likely not increase the current, and if then only slightly.
The chip itself on the PCB is most likely running with it's own crystal on a fixed frequency and wont be influenced by a changed refresh rate.
Overclocking might make it hotter since it needs to process and send data to the panel more often but that is a minor change.
A heatsink wouldn't do a thing to overclocking, better isolation of the cables probably would.
Remember, you're overclocking the display and not the display PCB. You're just letting it display more frames in a second.
Please reread this article: http://en.wikipedia.org/wiki/Image_persistence

And what do you mean about the display "crashing"? Do you mean that guy which got all these lines on his one?
That monitor probably didn't go into power saving mode and started displaying crap since it got no input signal.
I've never experienced this and I run mine at 96 Hz all the time.
The display controller doesn't have any problems in my eyes.


Oh and this panel doesn't use PWM light dimming for anyone interested.
See: http://www.tftcentral.co.uk/reviews/samsung_s27b970d.htm

Would be cool if this were a 10-bit panel, but you can't have everything.

So you're trying to tell me that increasing frequency while leaving everything else the same does NOT increase heat or electron flow, and that heat is not a detriment to overclocking computer electronics? Ever take a high school physics class, or overclock some piece of computer hardware before?

As for the PCB being unaffected by overclocking the panel, how exactly do you speculate that new data reaches the panel at a higher frequency than the PCB feeding it operates, unless the PCB is in fact being overclocked as well? The panel is only capable of displaying what it is given. It can't create new frames out of nowhere.

Who exactly is talking out of their ass here. My money is on the guy who just joined OCN and somehow think's he's the grand master of LCD technology because he opened his bezel, and has owned a few monitors before.

If you think you know better, prove it. Take some temps, do some testing, or provide a definitive article debunking the theory. Contribute some actual data or stay out of it and let the more inquisitive people test things that might actually help everyone in this thread.

And no, your wiki page doesn't count. All that says is that the burn in effect occurs. Great. It doesn't say anything at all about why it is happening in the first place in this particular monitor.

What video card, and are you sure it's not a single link dvi cable? There have been reports that some are being shipped with single link cables

My video card is a GTX 550 Ti and yes it is not a single link. I've tried both output ports. I have a second computer using the same video card but it'll take me a while to arrange some stuff around to test that. I also purchased two extra cables to try when I receive them: 28AWG off monoprice and also http://www.newegg.com/Product/Product.aspx?Item=N82E16812270191. Hoping for the best =X

Ah, ok, minor bleed, two spots bottom middle saw during a game loading screen. Also, panel slightly lower in middle than edges; can only tell from taskbar icons. None cut off at bottom but close. Observation more than real complaint...both could be fixed if I so chose.

I had the same issue. The bezel in the lower middle bows outwards. Also, when I had the 4 screws installed in the back along the bottom, the bow was worse. So I have no screws along the bottom currently

Does 96Hz no prob so far...can't say I noticed a difference yet though other than it was definitely a bit darker (60Hz ICC at that point).

Look at the OP for "Overclocking guide and Help" lol

Does anyone read the OP? doh.gif
