[Official] The Qnix/X-Star 1440p Monitor Club - Page 582

It is my belief that since these overclockable Korean monitors come with the Explore EP269 controller, they are natively capable of a 450MHz pixel clock (around ~110Hz roughly). The 96Hz is easy since other factors like cable quality, graphics cards, drivers (for those who don't apply patches), etc... come into play after. And to be honest, most of the people who overclock don't go all the way to make sure they're getting a higher overclock / lower pixel clock. They see a scan line and that's that.

Another limitation is the Samsung PLS panel that's used in these. Obviously, with the increased image retention, gamma shift, and uniformity issues (with high pixel clocks according to Spartan F8 - you're awesome), it's clear that these panels are made for 60Hz in mind. For those who cannot calibrate their monitors with a colorimeter / spectrophotometer, or cannot reach a desired gamma level that's pleasing to their eyes (subjective), or cannot find ICC profiles that make the monitor come close to their desired gamma level (again, subjective and not very accurate), they might prefer a lower overclock to reduce the gamma shift. I hope that doesn't seep into the overclocking results.

I'd like to test that theory (in the first paragraph) with a sample of overclockers who've only gotten up to 96Hz, hopefully when I get my monitor.

Damn! Really stretching the limits there xD

Hello, I was planning to buy a QNIX Monitor and a adjustable stand (This one: http://www.ebay.com/itm/120857358937?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2648) at the same time. Though, I was wondering if I have to buy new screws to attach the new stand to the back of the monitor or does it happen to have sufficient screws to work with? Thank you. :]

Ask the seller if it comes with screws because the monitor does not come with any. The adjustable stand I bought (different model) came with screws that were too long, so I had to use padding between the vesa mount and the monitor in order to get it sturdy. I could have bought different screws or sawed the ends off the included screws but I'm lazy.

Thanks for the reply, I'll ask the seller and see what happens from there.

Ask him from a different ebay account, if something goes wrong with your monitor they can use you opening up the monitor as a scapegoat to slither out of a warranty claim.

Pixel clock of 566.7Mhz for 153hz, it took lots of tweaking but it isn't too far fetched when you consider others have gotten to 120hz with stock timings which is just under 500Mhz. I have also seen people post they got around 130hz with just using precisionX. Now i have not played with precisionX but i am thinking it uses stock timings which would be like 540Mhz'ish. So those who have gotten to about 130hz with stock timings could go as far or farther than me with a good deal of effort. Or have a lot better stability at 120hz with the tighter timings. I don't keep it that high since above 140hz i start getting color retention and panel brightness uniformity issues again.

Really pushing the panel as far as possible and then stepping back to 120hz turned out to be a pretty good strategy for me. I run 120hz 24/7 and haven't seen an issue since i stopped messing around with optimization.

I just went ahead and pulled the trigger on a Qnix Matte 27".

Said it should arrive Tuesday-Friday.

I'll keep y'all posted.

Got mine last Wednesday. I havent notice a Dead/stuck pixel nor light bleed. was missing the US adapter (I used the same one i had for my monitors). Undecided if I want to mount it or not, not as wiggly as expected (not bad) .
