Defaults in Sierra to proper frequency and resolution.

The resolution is outstanding

Most people don't realize that the higher resolution will make icons and text sharper but also smaller

This display pushes your video card to the point that unless you have a really good video card, you won't get full resolution, therefore you may notice some fuzziness similar to using a laptop not set at the optimal resolution

If you are using this with a MacBook Pro with a USB-C port, I suggest connecting it to the monitor with a Mini Displayport to USB-C cable in order to have the best screen resolution and refresh rate

Great resolution

the 24" has the highest pixel density for the resolution -- if you go up to 27 or 28" you will get excellent resolution but not as

Cons: Shiny Dell logo; bright, constantly-on power light; middling pixel-density that makes "retina" resolution impossible and native resolution a pain, a decent industrial design hampered by a chintzy back port-cover and inaccessible ports when used as a USB hub

Gotta love that resolution. :-)

The resolution is outstanding

Resolution is killer and I love the ability to adjust resolution as a I wish and not be locked

Unreal resolution and a bonus digital audio port

You do lose resolution with the daisy chaining, I've considered getting a mini display port splitter to eliminate

OSX seems to keep the size of the fonts, text, and icons the same, but they have far greater resolution and detail, with less pixilation.

The native resolution works very well with Windows 10

The native resolution works very well with Windows 10

I have a 2yr old Alienware 14" with Win7pro, i7 processor, 16gbRAM, GeForce GT650M dedicated graphics which supports the 3840x2160 digital resolution, and also has the display

Have 3 of these, one of them (earlier revision I think) loses the resolution it's set to each time I unlock the computer

Cost effective and great resolution

But for the awesome resolution at this price, I'm not complaining!

I feel this monitor has better color rendition and of course excellent resolution.

The resolution is razor sharp when looking at pictures and videos

Great resolution and virtually no glare.

Yes, monitor can display 4k and also other resolutions quite well

I half thought that the resolution wouldn't be good enough for me to think about keeping

Even at the highest (meaning, most impractical) resolutions on both displays, the graphics issues are gone

I like the 4K resolution of this monitor.

I first tried a 28" monitor but the optimal resolution yielded font sizes that were just too small for my 53 year old eyes to read with comfort

The resolution and sharpness is very impressive

There is as yet no way to easily switch between best resolution and easy to read menus as explained above

Worked like a charm great resolution at

The problem with HD4400 on U series CPU is its maximum resolution is limited to 3840*2160 30Hz according to this(https://software.intel.com/en-us/articles/quick-reference-guide-to-intel-processor-graphics)

This monitor has good color and good resolution, but its pixels per inch won't jibe with the Mac OS or Adobe applications

I was able to get it to work a full resolution via HDMI, but the refresh rate is only 30Hz

Great monitor, it has great colors and resolution

Resolution is killer and I love the ability to adjust resolution as a I wish and not be locked

I like the resolution and size of the screen but there is a mayor problem with this screen, after my computer goes to sleep or

From the moment I connected it to my Macbook Pro Retina 13" (Early 2015) via the supplied DisplayPort cable it blew me away with beautiful 4K resolution

Many of the negative comments are that the monitor loses resolution when it goes to sleep so desktop icons have to be constantly rearranged when it wakes

A good HDMI cable that supports the high resolution

If used in easy, old VGA mode, resolution is not good at all

The resolution is great and the color gamut matches the iMac exactly

Feet - 4K Resolution Ready from the monitor to the

Great resolution

i'm running it at the full 4K resolution, beautiful

Extra resolution is a significant improvement for those who read lots of text.

Resolution is incredible, angle and color is just amazing

Most of the time I can get by without using readers for most of the day just because the resolution is so sharp.

The higher resolution is far easier on the eyes

If the mode doesn't appear press and hold ALT before click on the available resolutions

pro the resolution is amazing

The screen is reasonably bright, colors are pretty good and the resolution is great, but not as bright or as great as other displays on the market

Great resolution and easy setup.

The scaling options available for the built-in display also apply to this, and you can select a few awkward numbered (but great-looking) resolutions, one of which includes "Looks like 2560 x 1440"

Before you buy make sure you have proper driver that can support this 4K resolution

The monitor has great resolution and works great.

Spectacular resolution using my MacBook Pro 13-inch

I've always dreaded going back from my retina macbook to my desktop, but now I can enjoy the same resolution, except on a giant screen.- Works perfectly with OS X(Tested on Yosemite).

5K native resolution would be perfect, but that isn't ready for prime time yet

Very nice resolution

Just grab a thunderbolt to thunderbolt so you can take advantage of the amazing resolution.

Note that this does require DisplayPort 1.2 with MST (Multi Stream Transport) in order to support full resolution at 60Hz

The resolution looks good

Well I got the resolution, which is quite nice, but the light bleed is dramatic and noticeable when the lower corners are at all dark

Also, sometimes when the computer comes out of sleep, the monitor's resolution is capped at 2560 x 1440, and the monitor needs to be turned off and then on again to regain its ability to support the 3840 x 2160 resolution

the resolution and the fact it can be rotated makes my live easier (I like the 90degree rotation)

There is no native resolution available for the MacOS that fits my needs

The screen is reasonably bright, colors are pretty good and the resolution is great, but not as bright or as great as other displays on the market

Also if you don't have a 4K source, don't bother because the resolution doesn't look that good.

The display is matte (a must) and the resolution is amazing

Text looks almost as good as e-ink on a Kindle
