One 40" 4K has been perfect for me. Roughly the same DPI as my old QNIX (~110).

I got the Samsung UN40KU6290 (does 4k@60 with 4:4:4 chroma) for under $300. The PC mode is crisp and responsive. Calibrates well enough. Only complaint is slow GTG time can look blurry when scrolling text.

I've got a UN40JU6500 (40" 4K Samsung) on my MBP (15" late 2013) but it doesn't do @60, as far as I know.

Are you driving this from a Mac or from a PC? What kind of cable are you using exactly?

Both. For my mid-2014 15" MBP I had to get an active MiniDP-HDMI adapter. Looks like your MBP is limited to 30Hz...

Interesting! So it's not the monitor (TV), it's the MBP.

Oh well, will have to wait for the next MBP 15" refresh--don't see any real reason to upgrade yet to the latest TB MBP.

Plus, the @30 doesn't normally bother me, unless there's a solid large gray-ish color, which definitely shimmies.

These 40" Samsungs 4Ks really hit the sweet spot for Retina displays, at least for my old eyes. "Only" 1080P logically, but oh, so large and sharp!

Also, did you have to do any SwitchResX hackery? That's the only way I could get macOS to recognize the monitor as a Retina display.

Nope, but I run it at 100% scaling. I did notice that if the source on the TV is not labeled "PC" then the Mac uses YCbCr 4:2:0 and looks like garbage. Setting the input label to PC must send a different EDID because it seems to use RGB... On my Windows machine I can just override that in the nvidia control panel.

Oh, you run it at the full 4K (3840x2160) resolution? Must have good eyes.

Right, nothing works unless you label the relevant HDMI input "PC".

I bought this monitor the other week after hearing things like this but I couldn't get over two things:

1) It doesn't power off or on automatically. I need the remote 2) The viewing angle made seeing the corners difficult on my admittedly shallower then probably needed desk with no scaling, (40" seemed like the sweet spot for PPI without scaling).

How do you cope with (1)? I'm amazed that Intel, Nvidia and AMD haven't thrown a HDMI-CEC IP code into their GPUs and made it trivially to turn on and off displays over HDMI.

I just leave the remote on my desk and turn the eco auto-off to 8hrs so it doesn't turn off in the middle of my day. The TV controls the on/off of my receiver via CEC.

Seconded. I have the same monitor and it's a perfect upgrade from my old 3 27"-24" monitors. 40" seems perfect to not have turn your head too much, two would be too much for me.
