I've left it with Fedex (kinda trust them), and if I'm paying $50 surcharge I may as well just pay the customs charges.
Wow that sucks. To what country?

@Lawson make sure you test your downsampled resolution on a frame skip test. Many times the previously set custom downsampled resolution can "stick" and the refresh doesn't actually raise. I can set my Qnix to what ever refresh i want when this happens because the refresh is not actually changing. For example i set my Qnix to 600hz at one point to check if it was actually changing, after running a frame skip test the refresh was still running at 65hz(which was the last resolution tested). To fix this you need to delete any previously established downsampled resolution. Just to clarify, you literally cannot push over around 600mhz over the DVI port, cable, PCB. Now you can potentially push the virtual or downsampled resolution as high as you like keeping the refresh around 60hz with bios tweaks. By bios tweaks i mean forcing the DVI port into 3D mode(highest power state) which will make every false start resolution(pixel pixel lines at the top of the screen thingy) actually work. This has worked for another user i was PMing with a while back in which he achieved 5120x2880@60hz. Giving the level of downsampling is mostly dependant on the video card is stands to reason it may be possible to push the virtual pixels higher and higher with different Gfx cards. This is shown by some 1080p panel downsampling to well over 4K (which is also NOT actual pixels). Heck i have a laptop that can downsample to 8K@41hz but it is almost unusable (due to GUI size).

Also, the highest i have seen anyone get the Qnix in 4K is 77hz and that was with bios tweaks for the DVI port initial speed set. The DVI initial speed is generally 100mhz(which is why some of us run into higher idle states with certain timings) but forcing 3D mode can keep it at 400mhz which allows higher overclocks at downsampled resolutions. This was tested with a refresh rate multitool (to eliminate any false reporting from UFO test). So to clarify the highest to date (tested) downsample with no GPU bios tweaks is (to my knowledge) 68hz (by another user as i myself topped at 67hz), and with running the DVI port speed set at an initial MAX speed was 4K@77hz. So i would like to see if you screen is actually running those speeds at 4K, or if you are experiencing a "stuck" downsample refresh rate.

And to clarify NO this is NOT true 4K, it is downsampled which is a form of supersampling (OGSSAA to be exact). This is a brute force hardware form of supersampling and although is the most visually effective, it is also the most hardware intensive(because it is effectively only using hardware for the filtering). Sorry but we are not creating new pixels, the screen is only capable of 1440p thus making these "scaled" resolutions NOT native. You also will not blow up your PCB because when downsampling the scaling is done on the GPU which means the resulting resolution or pixel clock sent out the DVI port to the display has already been scaled and will be a scaled 1440p resolution. My 4K@60hz resolution after scaling actually only results in a 359mhz pixel clock (which is nothing on the PCB).

This is one of the best tutorial/explanation threads regarding downsampling.

Wow some great downscaling info there sparton thanks!...also your explanation makes perfect sense with some of the issues i was facing as in new resolution over writing the old etc ...i will have to do the UFO test later when i jump back into 4k mode as i went back to 2560x1440 due game FPS being a lot slower and the fact everything was so small at 4K. lol..But thank you for the info Sparton and for sharing the initial timings which i started to play with!...

Also my tests with downsampling and indeed yours seem to be showing that the old Qinx as in our Samsung PLS monitor can handle 4K downsampling a lot better than the new so called.. "true 4K Qnix".. if it can only downsample 4k at 30hz...i know this the very first resolution i tried i did UFO test at 55hz and was working fine with the UFO page and synced Valid at 55hz..and that alone is higher than the new Qnix if it can only downsample 4K at 30hz!...However i did not bother UFO testing the ones after as i was sure that they were working what with seeing the resulting pixel clock change!...i will do some more testing with 4K later and post the results...however what you say makes perfect scene now!...and the higher refresh rate simply could not sticking and i have certainly not tweaked my cards bios..ill do some more 4K testing later and post the results!...right to my next project now i need to sort out some new graphics cards that will fit into my case lol...once again as always thanks for the info Sparton thumb.gif

Are you sure?...i will have to call the store and get them to measure them before i buy them then?...however even power colors own web site clams these dimensions to be correct as in the link below!

http://www.powercolor.com/Global/products_features.asp?id=523#Specification

Edit:- i have just found a review which clams these dimensions...if true these will in my case biggrin.gif

The Good: This is maybe the best cooler ever put on a high end gpu. There are heatsinks for the vrms, a thermal pad over the memory, two massive heatsinks over the length of the card, and a bunch of copper pipes. My jaw constantly drops over the temps I'm getting. With a beefy overclock I can keep core and both vrms under 70c!! That's just sick. At stock clocks I can game and core and vrms will be around 50c. That's borderline water cooling level heat dispersion. Overclocking is silicon lottery but my card can hit 1230 core and 1700 vram.

The Squirrelly: Huge card. The listed specs are wrong, it's 294mm long and 52mm thick. Fans are loud from 60% on up and the temps I note above are with fans at 60-80%. But you can run the fans at a very quiet 50% at stock clocks.
Pro Tip: If you can deal with the size and fans that are on the loud side, this is the best custom 290.

Yes so i have been reading in a review i found below..and Thanks for the info Foreman and these will fit in my case and i have found them for only £310...result! thumb.gif

Good luck with your GPU decision lawson. Hope it all turns out!

For me, after testing so many 290(x) cards and 780 Ti cards, I just can't go back to Team Red but my 290 I tested was a fantastic card. I just like the Nvidia control panel and drivers way more. tongue.gif

Debating on ordering the new True10 display for testing but my glossy Qnix is so gorgeous and perfect, it's hard to mess around anymore.. bring on OLED! thumb.gif

Hi guys!
So I spent a good majority of 1hr reading through the OP! Some great info there +rep.
Going to make the leap in buying a Korean monitor.

Just on the fence with a few things:
-X-star vs QNIX - seems like there's no difference at all, but more people have QNIX ones. Any developments since? Would you rather prefer to buy one over the other?
-Backlight bleeding + dead pixel: Has anyone managed to contact the sellers and asked them to personally check it to make sure there's 0 dead pixels? I don't think my mini OCD will be able to stand a single dead pixel (yeah I know....)
-OC'ing it seems like 96hz is very much plausible
-Xbox360 connection is impossible -> sad face
-Nvidia SLI patch - is it really needed?
-Anyone purchased it from ebay via an "OFFER"? I saw people buying them for $270 (via the form) - how did you guys manage that?

Thanks for the help inn advance smile.gif
Really want to get this monitor, but not face problems with it and use it for as long as possible. (literally purchased another GTX680 yesterday, in order to run 1440p comfortably on my system)
I hope customs don't go crazy over it - already had one ebay seller say they can mark it as a gift for me.

Thanks for your help digital and i am about to place my order for 2 of them from the link below...it will be a tight fit with the top card only millimetres above the card below lol....Also i agree with you i also love Nvidia too!..however i can not find a GTX780 anywhere that comes near or close to the same price as the PowerColor AXR9 290 (PCS+ Edition) or i would buy them instead!...also i would hold back for a bit on the new Qnix..let someone else get if first...i bet NCX has already ordered his lol
