No one is suggesting a 40” 4K monitor at native unscaled resolution? That’s the best experience.
I agree 100%. I have a Philips 40" 4K monitor that cost just £500 & replaced a 30" 2560x1600 HP LP3065. It's pretty much the same pixel pitch as the 30" so doesn't strain my eyes at native resolution it just gives me an awful lot more screen real estate.
 
Just found this TV calculator. Very handy to know if the PPI will be too large or too small.

And it shows the PPI on a UHD 40" display is about 10% higher than the LP3065. Therefore, everything should looks about 10% smaller at native resolution.

This 110 PPI is very close to the 27" ACD (109 PPI by the same calculator). If you are OK with the 27" ACD's text size (which in my own situation is a bit too small, because my view point is a bit more than 2' away from the monitor), then 40" UHD at native resolution should be a pretty good choice indeed.
 
If your using a 40 inch at native rez, doesn’t it take forever to move the mouse curser around :D

I tried using UHD at native resolution some time ago. It's actually OK. Of course, the mouse speed / acceleration may need to be adjusted according. And since MacOS only allow to adjust the speed but not acceleration. Some 3rd party software may be required to make the mouse work better. But what I found is Magic Mouse is OK, Mighty Mouse is slow, and a good mouse pad really help.

The 10% smaller text doesn't bother me whereas 4K on a 27" monitor would be teeny-weeny at native resolution. My Philips 40" 4K monitor has actually been superseded by a 43" model which is nearer in PPI to 30" 2560x1600.

I use a 32" UHD monitor (138PPI) at 1:1 unscaled and find it nice to use. The only tweak I've made is to bump up Chrome's own rendering to 125% so that casual web browsing doesn't require sitting properly at the desk.

If you ask me, on a desktop workstation, being able to have large numbers of windows visible simultaneously is far more desirable than "Retina"-class PPI. I have no interest in @2x rendering in macOS if that means only having the equivalent of a 1080p or 1440p screen in terms of window real estate.

I have a Dell U2718Q. Love it. I run it at the equivalent of 1440p for UI scale, but OSX treats it as a full 4k monitor when it renders text and high-resolution photos and video.

Text is much, much sharper than a 2560x1440 27" display.

Most helpful post in the thread, thanks for the info.
 
I have a 28" Samsung 590D that I run at 1080 because everything is to small for me to get at a casual glance particularly Ps tools. When I buy the next display i.e. when 8k is not in the stratosphere I'll go significantly bigger.
 
Milage REALLY depends on your vision. I seem be lucky in this department, as I'm not exactly young anymore but probably won't need glasses until I'm around mid 50s if my parents are any indicators.

For 28 inch displays 4ks, I run at 3008 x 1692, for me it's quite legible and still sharper than a 1440p 27 inch, sorta the sweet spot as your'e getting roughly 27% increase on pixel density. I also run a MacBook Pro 15 at scaled to 1920 x 1200 so I'm more on the extreme end of viewing. The UI on a 28 inch at the later is still large to me. I seem to have better than average vision as coworkers suggest things are hard to read on my screen. Also above all else, get a monitor that's 60 Hz. At work I have an old Dell P2815Q and at 30 Hz its pretty crappy. Fortunately as a web dev, I mostly use this for displaying browsers, never using it for image editing.

If you're after pixel density: 24 inch and run it at 1920 x 1080p, it'll feel like MacBook Retina display.
If you're looking for the sweet spot of sharpness/size: 27 or 28 inch and run at 2560 x 1440 or 3008 x 1692.
If you're after size inch 32 inch and run at 3360 x 1890 or possibly 4k native if you sit exceptional close.

I personally would pass on 40 inch displays as I can't name any off hand that aren't TVs, and never seem to match accuracy or quality of PC monitors.
 
I'm running a Samsung U28E590 28" 4K (DP 1.2), driven by a R9 380X (DP) at 3840x2160. The UI is extremely small, however the screen real estate is superb. I have to be 18" or farther away otherwise I have to use my reading glasses - if I'm tired I end up using my specs anyway. I have websites at 150% to make it easier to read. I also have a GT120 running a 22" ViewSonic VA2238wm (1080) for those apps that have palettes and floating toolbars, plus for boot screens.

I really wish I could increase the size of the main top menu bar while maintaining the current resolution (i.e. the UI being twice as big). I don't want to increase everything, so a tool that gives granular control would be ideal. Does anyone know of such a tool? (I use SwitchResX but it can't increase UI)
 
Just to double check, the Geforce 680 can't do 4k @ 60hz if you're using the HDMI port - were you using the displayport connection?

Thanks for checking
Yes, I was using DP

Sorry never replied last year :)
 
For years I worked with a Dell 3007wfp-hc 30" monitor.

Today At work, I'm using a 40" 4K Curved AOC C4008VU8.
At home I use a 32" 4k crossover 324k

Both are run at HiDPI resolutions, that vary day to day with my vision.

Those looking for a low-cost 4K upgrade, I HIGHLY recommend the TCL 43S405/43S403 monitor. With a street price around $220, it has deep blacks, bright colors, and it can be picked up at your local Costco with a 90 day return policy. If your desk can handle the display, the 4k the dot pitch is comfortably close to what a 27" 2560x1440 display delivers.
 
I've been using a Samsung 40" 4k TV I picked up at Costco a little over a year ago. Cost me under $300 then, maybe less now. Pretty stellar. Been running under Sierra using an RX460. The only challenge was getting 60Hz to the TV's HDMI input; required an active DP to HDMI adaptor and Switch Res X to accomplish. May be easier now under a newer version of macOS. I don't know, 'cause I'm staying with Sierra at present.

Also, need to put your TV in "Game" mode to get good response.

Mojave finally supports HDMI 2.0, making the use of HDMI 2.0 displays much easier, opening up to much cheaper options without a DP to HDMI 2.0 adapter.

Thanks... good to know! For me, there are so many other potential pitfalls to moving to Mojave (my primary Mac Pro is the heart of my recording studio), I am happy to sit at Sierra for the foreseeable future.

Im using the Samsung 32" LU32H850 4K, 60Hz. Built in USB3 hub, Takes a second to wake (mBP Clamshell) always wakes though. It will allow PIP both inputs 4k so you could run as second monitor in one or another input.
I find the screen large enough, I was planning on another monitor but don't need it.
Small metal grey coloured bezel matched MPB looks great, all the cords tuck inside the back panel neatly. I like it

Looks great, especially for the price.
 
For those that are interested in a quality 27" 4K display .. LG is currently running a promotion on the 27UK850-W 4K display - $100 off @ $549. I personally bought this display about a year ago and would recommend it for professional use. I also game from time to time and the display does not disappoint.

In my humble opinion: I wouldn't buy a monitor with more than 12 ms average response time. With more than 12 ms average response time moving images (video's/games) look blurry.

Here a comparison with my monitor:
https://www.displayspecifications.com/en/comparison/241d9db13

The LG monitor has 21 picture modes of which 4 are just for gaming. I have seen no tearing or blurriness when playing under any of the 4 game modes. There's also a cinema mode -- again, no blurriness when watching movies.

The reviews speak for themselves.

Edit: It also has a custom gaming mode where you control the response time (4 settings), freesync (3 options) and a black stabilizer (control deep blacks).
