They come at 60Hz. I run the Matte version at 96Hz with the supplied DVI-D Cable and can do 120Hz with a better quality Cable - Some can do more. They are only DVI-D - No HDMI or VGA. HDMI can't do any more the 60Hz and what's the use VGA today. A GeForce 200 series will run them I believe you need at least a Radeon 6000 series to support 2560x1600 resolutions. I ran an eVGA GTX280 on a QNIX for a while and it worked brilliantly for Surfing and watching Movies.
For a Samsung 2560 x 1440 Res PLS Display for under $300, compared to Retailers asking $700 for them here - what more can you ask for at $300. I prefer the 2560x1440 16:9 screen over the larger 2560x1600 16:10 display.
Enthusiasts are aware of the back light bleed issues. Some are worse then others but if you're somewhat mechanically adept and follow the instructions on that site, it's not much to fix.
You stand less then a 5% chance of getting one with 1 or 2 dead Pixels. The two I bought from South Korea (One for a Friend) have no Dead Pixels. Paying for the Pixel Perfect option is a waste of money. If you carefully read their Warranty Print you will notice not one Vendor actually guarantees no dead pixels.
If damaged in shipment, DHL Shipping have great service (I had one damaged in shipment and had to return it with No Issues). If the Display obviously has Manufacturing defects, the South Korean Vendors are very obliging.
I love the QNIX QX2710 for BF4 and watching 1280x720 flics on a 16:9 screen - Highly recommended Display by me.
I'm seriously thinking about getting 2 more QNIX 27's and running a De-bezelled 3 screen 4320x2560 display on my own frame with Crossfire R9 290X's under water. I already have the Cards and my Platform Looped ;o)
$900 for say a 96 to 120Hz 4320x2560 for a Bezel-less Tryptych Samsung PLS display - Humm! - Full immersion Gamming.
I paid $268 for them a year ago. The price has gone up somewhat since then. They are definitely a Great Enthusiasts Display and priced right.
