4k monitors with 75hz and up

[raladin3D]

Hey all,

 

I currently own a syncmaster 940BW and looking to upgrade toward a 4k Monitor.

which is 75hz and not feeling like downgrading to 60 hz especially since I got used to 75hz.

 

Kept my eyes on Linus' 

ASUS RoG Swift PG278Q review, however he said that the colors were not the best.

 

I am also going to buy a new PC next year (7-9 months from now) with the best specs on the market, so my questions are:

• Is there any improvement/technology coming up in the monitor market that is worth the wait?
• will the prices of the the current 4k monitors (avg 900$) go down.  
• --> If so by how much? (rate)
• Should I buy something on black Friday or during Christmas time so the prices are down?
• Any suggestions on this matter?

 

Thanks guys, really appreciate it

unless u got quad sli titan X or any other crazy ass gpu configuration, dont even think about 4k and gaming especially if its 75hz coz ur gonna need 75fps for that ( let stand getting 75fps on 4k with proper settings, with everything low sure but thats not why som1 wants 4k )

I would suggest you try to overclock your monitor. For me, my monitor is happily running at 75Hz when stock it is at 60Hz. If you do not wish to overclock, you can always buy a 120/144Hz monitor but do remember that your graphics card must be powerful enough to run at that frame rate.

980ti 2-way SLI can handle than, medium high settings

current hardware isnt powerful enough yet to maintain 75minfps on 4k without reducing settings

[Valkyrie Lenneth]

980ti 2-way SLI can handle than, medium high settings

medium high looks damn ugly on almost all games, if u were to play on medium just to get 4k its better going ultra on full hd x_x

[pomaranc]

Well in most games I have played there is almost no difference between ultra and high, on medium settings you see a small difference and low looks damn ugly.

That is wrong, even 2 Titan X is more then enough to maintain 4k 60fps: http://www.digitalstorm.com/unlocked/4-way-sli-gtx-titan-x-4k-benchmarks-review-idnum347/

check minfps, not only average aswell try it on far cry 4 and newer games instead of older ones x)

1 card gives 33fps min at 4k (in far cry 4), so SLI min cant be that bad.

sli wont be enough, 3-4card maybe but then ul get microstuttering issues eventhough u can run it

 

and thats looking at far cry 4,  wait till the newer games come out soon

We dont got a monitor that goes beyond 60fps yet, meaning you only need to hit the 30-60fps range, which 2 high end gpus can handle. Heck, you are able to pull it off with 1 card, if you dont mind lowering the setttings.

ummm hz is equal to fps  60hz monitor will allow u to see 60fps maximum, 120hz will allow u to see 120fps maximum, hence why vsync syncs with ur monitor 1:1 ratio

60hz is the limit of 4k panels atm, so will take a while before we see higher as they need to wait for display port 1.3 or higher first.

If that is to low, get one of the new 3440x1440 monitors that comes out this year. They should support 60hz+.

75hz 4k

ASUS said: "4K at 120Hz (or 8K at 60Hz) will require DisplayPort 1.3 (which is not a finalised spec yet), and we estimate 1-2 years before there is the DP 1.3 spec, GPU support, and a scalar chip for the LCD electronics that could support this. HDMI 2.0 is only good for 4K at 60Hz"

 

Frequency Horizontal: 31.5-134 kHz, Frequency Vertical: 30-75 Hz

Its newegg that got the info wrong, as Frequency got nothing to do with refresh rate (fps).

Even reviews says 60Hz is the limit: http://www.pcmag.com/article2/0,2817,2463609,00.asp

 

Edit: http://www.tomshardware.com/news/nec-ea244uhd-ips-4k,27230.html

"The panel in the monitor is capable of refreshing at rates of up to 75 Hz, though the DisplayPort interface limits that to 60 Hz due to bandwidth limitations."

So guess you get 75 Hz at lower resolution, but not at 4k.

DisplayPort 1.2 has enough bandwidth for 4K 75Hz, Tom's Hardware, PCmag, etc. are wrong. Someone somewhere made an assumption and everyone else is likely just repeating it. Such is life on the internet.

HDMI 2.0: 14.4Gbps

DisplayPort 1.2: 17.28Gbps

[Chiobe]

DisplayPort 1.2 has enough bandwidth for 4K 75Hz, Tom's Hardware is wrong.

Maybe, given that we now are getting 3440x1440 monitors with 75Hz (maybe even 100Hz), but we have yet to see anyone even hint at 4k 60Hz+ yet.

How many Gbps does 4K push @ 75Hz then?

[Glenwing]

How many Gbps does 4K push @ 75Hz then?

3840x2160 at 60Hz/24-bit color: 11.94Gbps

3840x2160 at 75Hz/24-bit color: 14.93Gbps

Though you need to add about 10% or so for timing format overhead.

Well, I don't know how you've calculated that, or if it really is that simple, but your assertion that "someone somewhere made an assumption" is definitely incorrect, as numerous manufacturers have said 4K is limited to 60Hz with DP 1.2, and it even says so on the Display Port website. So either your math is wrong, or perhaps it's more complicated than simple bandwidth numbers... OR it's one big Illuminati conspiracy which the monitor manufactures and Display Port themselves are all in on, for nefarious and sinister purposes we can only guess.

Keep in mind that official specs tend to stick to standard frequencies, not inbetween. For example, HDMI 1.0 caps at 1920x1080 60Hz officially, but that's not the EXACT limit. It has enough bandwidth to do 61Hz, or 62Hz, or 63Hz, or 63.1Hz, or 63.2Hz, etc... But generally they only list the highest refresh rate that displays and/or content have standardized around, which is 24, 30, 60, 120, and 144. 75Hz, while not completely non-standard, has been very much in the background since the days of CRTs, and isn't really considered by most to be a standard frequency that anyone cares about. Whenever a manufacturer says "DP 1.2 maxes at 4K 60Hz", it's in response to someone asking "are you going to make a 4K 120Hz monitor?". But 75Hz would be doable. It's just that no one cares about that number

Riddle me this, HDMI 2.0 can do 4K 60Hz, and DP 1.2 has 20% more bandwidth, so where does that extra go if DP 1.2 also caps at 4K 60Hz?

And the calculation for bandwidth is really pretty simple if you have 3840x2160 resolution, that's 8,294,400 pixels per frame. At a color depth of 8 bits per subpixel, that's 24 bits per pixel (8 bits for red, 8 for green, 8 for blue), which is 199,065,600 bits per frame. At 60 frames per second, that's 11,943,936,000 bits per second, or 11.94 Gigabits per second. And consider an extra 10% or so for timing overhead, usually I assume CVT-RB is being used.

Basically, 3840x2160 at 60Hz/24-bit color is just 3840 x 2160 x 60 x 24.

"DisplayPort 1.2a systems today can support 4K displays at 60Hz refresh and full 30-bit 4:4:4 color (non-chroma subsampled)"

That might be where the extra bandwidth goes.
