I just gave this a go by making some custom resolutions and it works fine, black bars as with the Philips (and obviously you could use GPU scaling if you wanted). 3440x1440 looks quite ugly as it's scaled, but 3840xWhatever comes out native, perfectly sharp.
I have never seen such a fragile screen coating as whatever these have. A client has just ruined two of mine by tapping lightly on them with her pen when pointing things out - each tap has left a permanent cluster of glowing pixels behind! Black screens now look like a constellation.
Oh absolutely yes, it's an actual physical thing. It seems the VA coating is incredibly thin, so a tap creates a tiny prism in its surface that appears as roughly 2x2 stuck pixels on any dark background. See blue dot beside the cursor for an example. That was made yesterday by tapping the screen with less force than it would take to click a mouse button.
I have access to the Philips to compare, but obviously I'd rather not start cutting notches in it to find out! I can say I haven't found any similar defects in its screen surface having had it for some time, whereas these ones appeared in the Iiyamas very quickly.

Not having much luck with these are you? I'd be billing my client for the damage! I remember years ago a client jabbing a pen into the screen of my brand new laptop screen and them being taken aback with me freaking out about it. Cheeky gets!!
I've been thinking that too, but I have to keep rationalising it on the basis they were very cheap, and I shouldn't expect the earth from £1500's worth of monitors. As you say, I could tack that on the bill of any of my clients and they wouldn't even notice, but for once I'd feel bad as she really didn't seem to be doing it hard enough to leave a mark.

THANK CHRIST. I thought I was going mental. As you can see from previous posts, I have a screen that blanks out on certain images, and got refused an RMA. I expect it's a problem with the onboard display controller. I will try your image once I'm A) home and B) sober.
Yeah that's similar to what I found: it's to do with frame complexity, rather than frame rate or cable bandwidth. It's like the monitor can't reliably decode static 4K frames if the image is too detailed.hmm it also does this with HDMI 1.4 4k@30hz thats weird
I'm on Nvidia with a stock BIOS, but I agree it seems to be signal related. Does anyone know if there's a way to boost the DP output from NV cards?i reflashed my card with different vBIOS and it seems to help that flickering a lot (but still can be seen once every 10sec on that image
