Thank you Bethamon - that's what I was wanting for confirmation. Nice monitor over clock.

+1 Rep incoming for taking the personal time to provide this info. thumb.gif

So I went ahead and tore my new Qnix apart and did the tape mod.

I found the Youtube playlist to be very helpful, and thanks if the guy who produced them ever reads this, but a bit scattered.

In a more concise fashion:
To do the tape mod, see the playlist listed in the FAQ and others have mentioned that starts here:

https://www.youtube.com/watch?v=IoxFU04b1Iw&list=PLnVkA6ZcoQv5piavGXZDJv3Wj2E4MT_iE

Watch videos 1 - 5, skip 6 - 10, watch 11 - 13 and stop. Assembly is the reverse.

That said, as others have mentioned in this thread as well, my biggest issue was a giant arse bend in the frame that was putting pressure on the top-middle-left portion of the screen seen in my earlier pics.

green-sum claims to inspect every monitor before it goes out but clearly they're fibbing. I'm guessing this damage had to have happened at Samsung before the sub-panel was even assembled. I don't see any impact that could bend a folded steel frame could not have broken the glass of an LCD panel.

Once I fiddled with the frame on a flat surface for awhile and got it mostly flat and torqued back mostly square, I went ahead and applied the electrical tape because why not.

100% better!

Thanks everyone.

I highly doubt that any seller checks anything, regularly.

None of them source their own monitors, so they are just resellers (middlemen). To check them, they would have to open a retail box, plug it in, turn it on and test (by eye?). That takes time, that takes energy, and most importantly, it results in an opened box. It's all well and good if the monitor truly is good, but what if it isn't (and many aren't)? You now have an opened box monitor; not exactly prime goods anymore. So you sell it as non-pixel perfect, for less. People who catch on to this scheme decide not to buy your non-pixel-perfect monitors and go somewhere else, since they know all your reject panels are going to them. Then the person you DO sell one to complains about it because, well, it was opened! What recourse do you have? None, not really. Lot of risk. Costly process. Very little return on investment (if any). And it serves one line of business ("pixel perfect") at the expense of another line of business (non-"pixel perfect"). I know that if a seller does this, I'd stay far, far away from his or her panels that aren't "checked".

If anyone checks, it's most likely done at the factory level. It's the only place where any of this makes any kind of economic or business sense. Do it when you can do it en masse, when you can automate it, and where you don't need to tamper with retail packaging.

I've not seen a frame skipping test in this thread with any more than five squares yet, unless I've missed it. Need to slow your camera capture time down.

Right now, your frameskipping photo is currently currently capturing too few frames; try for a longer camera exposure.

To trick any cheap camera into doing that:
1. Adjust your "Exposure Compensation" setting in your camera to a higher setting; and
2. Lower the brightness of your monitor by a lot. This forces your camera to take a longer exposure.

For easier frameskipping determination, you need to take a picture of at least 1/10th second (capture about 6+ squares), and preferably 1/5th second (capture about 10+ squares) for a more accurate frameskipping analysis. The first visible square should be more than 2 squares away from the last visible square, or it won't easily help you determine frameskipping.

Example valid photo of non-frameskipping:


Example valid photo of frameskipping:


But yes, very good test of the frameskipping & you have correctly determined your display is frameskipping at 85Hz. I've amended the instructions at www.testufo.com/#test=frameskipping to also use a longer camera exposure, since it makes it much easier. to detect frameskipping.

Secondary verification tests: The moving photo test at www.testufo.com/#test=photo should show obvious microstutters on a frameskipping display. (provided your GPU/browser is not the bottleneck, but it appears this is not the case for you as Chrome manages perfect synchronization running as the only window on systems that has everything chrome://gpu is enabled). Frameskipping will be much easier to see when playing VSYNC ON than when playing VSYNC OFF. Strafing left/right at high speeds at close distances to high-detail objects during fully synchronized framerate=Hz VSYNC ON will show microstutters on a frameskipping display.

Added this to the OC section in the OP.

Hey guys do your monitors make cracking noises when they warm up? It seems to be coming from the front(bezel I guess?). The panel itself is most likely quite hot and I've loosen the screws a bit so that would explain things. Anyway, I hope it's not a sign of imminent(and premature) death.

I'm on the same boat. I'm giving him until the 28th to ship before I take action.

My transaction is already completed and the money is drawn from my account. How were you able to cancel the order? Did you file a dispute? And then what?

I dislike the lack of communication and excuses he gives for the delays.

Yeah...not trying to rub salt in wounds here rather reiterate to others who have yet to buy--avoid Dream-Seller.
