That's pretty cool. I wonder if it's a genuine card using polaris? I've seen a few chinese cards on ebay that say they're GTX 10xx, but end up being rebadged gtx 7xx or 9xx.
No, it could be your display that is f'ed. Or your graphics card output. Which neither a screenshot would show.
But yes, it could very well be the cable. Can you not try a different one? I'm sure it should be extremely easy and cheap to come across a different HDMI cable. Probably easier than...
Honestly your image is pretty much useless. You don't see black crush, but you don't really see anything pitch black do you? It looks your dimming isn't functioning correctly at all.
RTings is full of shit because they only reviewed the 65" model.
Anyway, I traded my Q9FN for the 75" Z9D and the Z9D was the superior set in almost every single way (except for input lag).
The black crush and processing on Q9FN is absolutely horrid.
Again, Z9D or bust.
Cable shouldn't be an issue. It's probably the GPU's 400mhz RAMDAC limit. You could try overclocking it but I don't know how. If you find out let me know.
What FPS are you targetting? If it's higher than 120, then your CPU will be the bottleneck or the SLI bridge.
In fact, why is your 8700 @ 4.6 ghz? Mine is running at 5.1 using a moderately cheap air cooler..
Don't get anything short of a 1080 Ti for 4K gaming. Even 1 1080 Ti isn't enough for me.
So either look for a used 1080 Ti or wait for a sale on a 2080.
The only way would be through a Sencore CR70 or a CR7000. I don't recommend it since those can be pricy though, and if you try the rejuvination process on H-K short, it could kill whatever little life there was left.
You can get rid of the banding by switching to a 4:4:4 chroma on the nvidia control panel, instead of going RGB, right? At least that's what worked for me.
I was unable to force my PG279Q to 75 hz and unable to get my FW900 to 85 hz. So with PG279Q @ 85 hz and FW900 @ 75 hz, they are pretty much neck in neck, though I don't think it's a fair test without the refresh rate being the same. I tried CRU to force the PG279Q to 75 hz but that didn't work...
The reason I couldn't do that initially was because my 1080 Ti doesn't support analog out, and my DAC adapter doesn't go all the way to 2560 x 1440. But now thinking about it, I can look for a miniDP to DP cable and see if I can use my laptop with a gtx 660m and vga out for the test. I'll report...
You're right, it wasn't set to it's optimal setting. Since to do the test, I had to set it to the lowest common denominator - 2304 by 1440 @ 85 hz. However, even so, I don't think 16 ms is unreasonable at all. Very rarely have I seen a LCD have a input latency of less than 10 ms (via leo bodnar).
