Sorry if that was unclear, for 4K @ 60Hz you need DisplayPort OR MiniDisplayPort. HDMI will only do 30Hz.
If you're asking for the technical reason its basically because HDMI can only send so much data per second, and 4K requires about 4 times the amount of data to be sent from your graphics card to your monitor compared to 1080p. (as xela says, there is a new version of HDMI with more bandwidth, but not many things use it)

This is a really good deal, just remember you need an appropriate graphics card to game on this beast.
980ti/Fury X are almost required if you want decent FPS in the newest AAA games.

People don't change. People are wrong and when they find this out they change their minds. People like me try to tell everyone they're wrong but we're often ignored.
Blanket statements like "X inches is too small" are often wrong although they might generally be correct.The resolution you can perceive depends on several factors: Visual acuity (i.e. good eyesight), screen size and distance from your eyes. A phone screen is tiny but you can, and sometimes do, hold it as close to your face as you can so that it fills your entire field of view. For a TV to do the same it might need to be 80 inches from 6ft away so to get the same effect you'll have to either buy a bigger TV (unless you already have a TV that fills your FOV) or sit closer
I would say that I can tell the difference between SD and HD on a 22" screen from over 10ft away, other people might have to be closer or have a bigger screen. Some might be able to see a difference further away. I haven't been able to check UHD yet but having had a 1600x1200 monitor 15 years ago I really miss it simply for it's larger desktop space (i.e. you can fit more on a screen meaning you can read more lines without scrolling say). For a monitor I believe that it's going to be noticeable at 22". For a TV it might be necessary to get one slightly bigger than you currently have but it's worth knowing that UHD blu-ray offers other benefits such as HDR and more colours that might contribute to a better picture as much as the increased resolution
This test seems like a good indication, people could see the difference even though charts suggest they needed to be at least a foot closer to tell the difference.

So - I was in the market for a 1440p 24/25 inch monitor for my gaming setup (R9 390). From what I've seen, the general prices seem to be around the £200 range, so I might as well go for this?!

4k on a 15" laptop is still preferable to not having it for me I'd say - you do get some scaling issues, but generally it works pretty well in windows 8.1.
Saying that, if you've got the space etc, I'd go for a 28" 4k - I'm planning to get a 30hz 40" 4k for coding at home when they're cheap (have the 60hz 28" at work.)
xela333 to _g_
22 Oct 15#39
Don't do it, even for coding 30hz will be awful.
arfster
21 Oct 15#37
The problem is a lot of Windows apps still don't scale well at present, so you end up with awkwardly microscopic scrollbars and so on.
Of course if you sit ultra close to the monitor that's less of a problem.
Really nice price if you have a use for it though.

I had a Sony CPD-G520 CRT monitor, which was advertised as handling 2048x1536 on a 21" CRT (so 19.8" visible). That's 129 DPI. The only reason I didn't use it at this resolution is things became rather hazey, which combined with things being small didn't make for a good experience. But if it was pin sharp at that resolution I'd have used it. Based on this I'd say 32" is the ideal size for UHD on a desktop computer, which equates to 128 DPI. Something smaller would be great as a secondary monitor for photo editing though, particularly if it can accurately represent colour.

Am I missing something? '4k only worth it on 55" screens' folk screech, but a 24" monitor? What is the point?
Surely 39" > is the ideal to take advantage of the capabilities of so much screen space.
fighting_stupidity to simont_space
21 Oct 15#13
Depends on your eyesight :P
Also your OS should have a DPI setting, so everything will remain the same physical size (compared to a 1080p screen) but it will be sharper and clearer due to being made up of more dots.
xela333 to simont_space
21 Oct 15#14
Big difference in how far you sit from a tv compared to a monitor. I agree you really want to go 28" as a minimum for a monitor at 4k but as this is close in price to 1440p monitors of the same size, might as well get this.
RyanBest to simont_space
21 Oct 15#22
The closer to the screen you are the more pixelated the image looks. When you watch TV you tend to be a few metres away. That means all the pixels blend together and doesn't look as bad compared to sitting right in front of a monitor/tv.
You can test this out yourself. Sit right in front of your TV and then step back a couple of metres. You'll noticed a big difference.

People change, 5 or 6 years ago people were saying 1080p was only useful over 32 inch and 37 inch was the recommended minimum, now I see people say stuff like monitors over 22 inch need above 1080p.
In a few years time people will be saying 4k isnt enough for a 22 inch monitor.

Exactly. I use a BDM4065UC 40" 4k 60Hz monitor as my prime screen and its equivalent to 4x 1080p 20" screens.
And with this monitor you can allocate portions of the screen to different inputs, so it can show output from 1-4 machines.
Great monitor...
In fact, its price of £550 is comparable to the price of 4x 20-22" IPS monitors too.

I currently have two BenQ 1080p 24" monitors and am thinking of replacing one of them with this. Would I notice an improvement? I would also be using it as my PS4 screen when I am using that (instead of one of the BenQ's like I do right now)

What graphics card would you need to get decent fps at native res on this?
xela333 to rmg
21 Oct 15#12
If you want 60fps on new games at native res at max settings, ideally a 980ti. Otherwise a 970 or a 390 will give you decent results on high to medium settings.
fighting_stupidity to rmg
21 Oct 15#15
For gaming you'll need an AMD 290 or better, or an Nvidia 970 or better, depending on game and settings of course, but those are the entry level 4K gaming cards.
For desktop use, internet and office use, any GPU should be okay.
The important thing will be that you use a display port (or mini display port with adapter) to get 60hz.
I find 30Hz really terrible to work on.
Dan_the_man28 to rmg
21 Oct 15#28
An R9 290 will get 42 FPS in Star Wars Battlefront at 4K high settings
Correct, AMD dropped the ball with HDMI 2.0. Not even the Fury X has it.
LoveHdukNotReally
21 Oct 151#25
The bigger the better really, so ideally a 40-50" is like having 4 x 20-24" monitors 1080 stacked together. I tried 24" and 28" but the detail is lost unless you have the optimal vision and sit very close to the screen.

21 Oct 15#23
For those of you saying you need a minimum of 28", I have a different 24" 4K monitor and there are still benefits to having a 4k monitor at this size (e.g. workspace).
For me a 28" would have been too large both in terms of desk space and comfort; the issues I do have would be the same regardless of the screen size.
Cool thank you for clearing that up , you learn something new everyday ! :smiley:
