It is just because 4k displays are out now, so obviously 4k must be the best?
Objectively higher resolution gives you better image quality and more desktop space, for those people interested in quality then yes they will probably be interested in 4k. This is hardly new, people have been interested in higher screen resolutions since we've been able to produce displays, every few years we get new standards with bigger and better resolutions, 4k is in no way any different it's just that there's a corresponding media standard like with 1080p that means it will probably be adopted a lot for home cinema/tv/movies.
Yup, just give me a 32", 1440p, 144Hz IPS, freesync monitor.
And the bad colour that goes with trying to run IPS panels with slow pixel response rates at 144hz.
When I can get a single $400 GPU to game at 4K then I might care.
In what games?
The vast majority of games out will run just fine in 4k with either max settings or close to max settings, there's only a handful of games that require any significant sacrifice to achieve 4k, I play games like GTAV in 4k on my GTX980 OC and last night was playing Wolfenstein Old Blood in max settings and 4k with 2xMSAA and it looked amazing.
If you want 4K, I think 34" monitor is the minimum but then that means you need a minimum of 2 high end GPUs or preferably 4 to sustain a 60+ FPS.
It turns out that at least for me 32" is actually comfortable to use at 4k, and again what GPUs you need for 4k depends on a few factors like what games you're playing and in what settings. If for example all you play is CS:GO and DOTA then 4k is absolutely do-able with a single high end GPU, if you want absolute max settings in the latest AAA games at 4k then you'll need a few GPUs, if you can handle disabling 1-2 performance intensive graphics options then you'll run a lot of the modern AAA games at 4k just fine.
And most of the 4K panels are TN based which kind of defeats the purpose for gaming.
Most of the 1080p panels are TN based, so what? There are IPS 4k panels out and I have one, and it blows my old 2560x1600 IPS out of the water, this is simply a non-argument. If you want IPS then don't buy TN, obviously?
The major advances in panel technology have been with G-Synch / Freesync along with IPS displays fast enough to game with
All of which are either available in 4k or coming to 4k this year. My 4k IPS is 4ms and great for gaming.
At over a grand, it's not exactly available.
There's loads of cheap TN 4k panels around now if all you're interested in is additional desktop real estate for work/productivity, you don't need to spend $1k
4K monitors are great because of the super high PPI and fidelity you get from that. Unfortunately we don't have GPUs really up to the task to run that as a gaming resolution without compromises. So it becomes a choice of great pixel density but turning game settings down or maxing game settings at a lower resolution.
See this is a fairly balanced point of view which actually acknowledges the nuance. It's worth saying that if you're a long time gamer who has a large library of games (my steam list is over 500 games) then the vast majority of them (99%+) will run at 4k maxed out just fine on a single high end GPU.
It's only the handful of super high end AAA modern games which push the boundaries such as GTAV which need any significant amount of settings to be dropped. And lets be completely fair here, most people with high end GPUs cannot run this game completely maxed out even at 1080p because they left the graphics scaling of the game very open ended. Chasing the white rabbit of maxing things out in some circumstances is just silly.
If this thread teaches us anything it's that people are generally extremely misinformed about 4k and benchmarks of the absolutely harshest graphical games in 4k does not translate to real world experience.
If we used this same bent logic we could also say that 2560x1600/2560x1440 and even maybe 1080p are simply not playable on a single high end GPU because there exists a few games which you cannot max out, it's just dumb.
