I'm not a fan of curved especially after trying it and even having flat and curved of same size to use, it messes with everything for me and I can't use it for web, movies, games, ...
Still the Samsungs are nice on paper but in reality to get a good one is a huge lottery. I don't really test HDMI other than briefly to check that it works at all, the C27HG70 should run 144Hz over HDMI but Freesync only up to 100Hz? (At least PCM mentions so.).
4790K supports 2160p60 over DP, so it might do 1440p165 but HDMI probably only up to 1440p75. Or only 1440p120 over DP?
I would not bother with the old M270DAN2.x panel based monitors, similar awful lottery + blurry issues. Wait for the newer Innolux panel based in 2019 to be in shops, it should be in Q1. The LG panel... that's probably 2020.
Samsung has JG50/52 now that are cheaper but have features cut down.
LG 32GK850F is now at 500 EUR finally on Amazon and other German shops at least since December. Finally that one dropped to a more sensible price after being dead price flat for a very very long time at 600. That would fit your budget now, or 650F variant. Or curved BenQ variant probably too.
You've already tried DP+HDMI from iGPU at max that it will allow probably so the only thing left is to try a different GPU that can do that max refresh rate if the iGPU can't. If it's doing only in games and not elsewhere it's very weird and could really be some GPU issue. Sucks to troubleshoot these things when one doesn't have spare extra hardware at hand to test with. The monitor nor GPU output should really care what the input is from (game, movie, desktop) and if it blinked all the time it could be a cable but it's not. My experience so far with poor cables is that a selected option of refresh rate will not work at all when the cable can't keep up, set it, goes black screen and reverts back.
The fact that you have all these model numbers memorized almost makes me anxious.
Thanks a lot for your time though man! Much appreciated!
Well, I wanted a monitor now just to escape from the god awful 1080p TV I was using before. That was nice for movies and stuff (40 inch monitor? Oh yeah... SOMETIMES), but games? Nah, the input lag and pixel density were terribad. And with that said, my budget is going to be constrained for just the next few months. I just graduated and I'm gonna start proper work by the end of February if all goes well. But I want something to use until then, so I don't really want to return this and wait. The monitor I got is otherwise fine. Colors are pretty accurate (or at least seem so), there are no dead pixels, response times are as good as any other monitor in the category, viewing angles are decent... Even the curve isn't bothering me as it does on TVs. It actually bothers me a bit when surfing the web, but I actually kind of like it in games, so meh, it all balances out.
Now, I spoke with another friend and she's gonna lend me her GPU (an R9 380) tomorrow or the day after, so I'll get to try it with that. I know it's not much better than my own GPU, but at least I'll know if mine is downright problematic.
The other thing is, I'm starting to lean towards the cable again. I did a short search and I've seen at least one other person with a completely different monitor and GPU that had the exact same issue because of a bad DP cable. So, having spent 13€ already on this cable, I'll probably order a DP 1.4 certified cable that has good customer reviews from Amazon and see how that goes. I will also speak with Samsung support and ask them about it. I doubt they'll be much help on technical matters, but it's worth a try, at least.
Regarding the other monitors you referenced... I suppose the M270DAN2.x is the panel on the Asus? If so, yeah, I've heard some issues about it too and that's part of the reason I didn't buy that. As far as others go, the market in Greece is very limited on 1440p 144Hz monitors and shipping one from Germany or whatever would cost quite a bit, just exceeding my budget. I was in a pretty tight situation here, really should've gone with the 1080p options I had and make do until I could really afford better. But I yolo'ed it and I'm paying the price.
Whatever the case, by the time newer panels release, I'll be able to afford them for sure. It's the now that's problematic, but after experiencing 1440p 144Hz I don't want to go back to 1080p 60Hz and over 100ms of input lag. So I guess I'm stuck with this one for the time being, unless I RMA it or it really is the cable/GPU that's the problem. Oh well.
PS : Yesterday, I played R6S for about an hour with no problems. Then I decided to fire up Dragon Age Inquisition and it was unplayable. Black screen, back on, black screen, back on, black. Then "Not optimal settings, recommended settings 2560x1440 144Hz" message pops up and it stays that way until I alt+tab out. Then I go back to the game and it went black a few times, but then started playing. Sure didn't look like 1440p although I had it set to 2560x1440. I'm at a loss.
