    Treat your eyes to the highest definition and resolution using this 28" 4K 60Hz Monitor from Monoprice!

    This monitor boasts a native resolution of 3840x2160 pixels with a 16:9 aspect ratio. It features five video inputs, including two HDMI®/MHL™ ports, a Dual-Link DVI-D port, and two DisplayPort connections.

    The HDMI/MHL ports allow you to use a passive MHL cable to connect your smartphone to the monitor. The monitor will provide all the power needed for the MHL connection and will charge your phone at the same time. It will also work as a normal HDMI input port, supporting all the features listed in the 1.4 specification.

    Unlike most other 4K monitors, which only support the 4K resolution at a sluggish 30Hz, this monitor supports a full 60Hz refresh rate at the 4K resolution on both of the DisplayPort inputs, so you can take your gaming to the maximum level without compromise.

    The monitor has a 3.5mm TRS audio input jack, so you can connect your computer's audio output to the monitor and use the built in 2-watts/channel speakers. When using HDMI or HDMI/MHL video, the audio is automatically output to the speakers.

    Graphically, it features a 1ms response time and a 1000:1 contrast ratio (typical). It has a brightness of 350 cd/m2, a 170° horizontal viewing angle, and a 160° vertical viewing angle. The glass features an antiglare coating.

    The included stand allows adjustment in four dimensions: height, tilt, swivel, and rotating, so you can easily switch from landscape to portrait orientation. It has a 100x100 VESA mounting pattern.

    Note: This monitor supports the 60Hz refresh rate on the DisplayPort inputs only. For the optimum (60Hz) experience, you should use a DisplayPort 1.2 cable, such as PID 10582. Note that a DisplayPort cable is NOT included with the monitor.

    IMPORTANT: This monitor has a "demo" mode, which can be activated by pressing and holding the SELECT button for about 8 seconds. To exit demo mode, simultaneously press and hold both the UP and SELECT buttons for about 8 seconds.

    Fantastic Monitor with some small quirks

    • Direct,
    •  Toms River, NJ

    Pros: PRICE!!
    Fantastic color, great size, good response time, little input lag (more details in the review).

    Cons: Running the display at anything other than 3840 x 2160 causes lag
    2 pieces of dirt trapped under glass
    1 stuck pixel (barely noticeable)
    A small smudge under glass
    Mild darkness on left edge of screen

    Out of the box: I fell in love with the screen. At first I had the monitor at the back of my desk about 2.5ft from where I was sitting and found myself thinking everything was small, but that was expected. Normal people may turn on GUI scaling in Windows or use a Retina/HiDPI mode in Mac, but I purchased the monitor to increase screen space. So I moved the monitor to about 1-1.5ft from my face and was much more comfortable. :)

    Gaming Performance: As someone who dabbles in CS:GO, I would normally run CS at 720p to gain the highest framerate and lowest lag (on Mac OS with a GTX960 btw). Immediately firing up CS:GO after changing my desktop resolution to 720p (without scaling) caused a noticeable input lag. This is due to the monitor having a TV-like upscaling system built in. The upscaling algorithm is fantastic too, but not great for gaming. My solution was to simply run Mac OS at one of the HiDPI modes (or native 4k) and leave CS at a low resolution. Besides that small work around I think it is perfect.

    PROBLEMS: My main complaint is the fact that there is a stuck pixel, and 2 or 3 pieces of dirt stuck beneath the glass. Truthfully it's not that big of an issue but it is noticed on bright backgrounds. The only other complaint is a very mild darkness on the left side of the screen. It is (without knowing how this monitor was made) as if the backlight diffuser has been slid to the right of the panel. Not that large of an issue.

    Overall: I love the monitor and the productivity boost having more screen space enables is totally worth the small resolution workarounds needed for gaming. :)

    Beautiful housing. Looks absolutely wonderful on my desk.

    Pros: High quality bezel, great price, decent size/res ratio, 60hz, one-year warranty.

    Cons: Signal receiver seems to die after a few weeks. Good thing theres a one year warranty!

    I bought this in April after deciding that I needed to be better than everyone else by having a 4K screen. I sure pulled that off! Luckily had no dead or stuck pixels, very little backlight bleed or color issues. It has a reflective plastic screen but I dont find it to be too reflective as long as I place it at a proper position to stay clear of light. It has a stable stand and a strong aluminum bezel that makes it seems expensive. The ports in the back are all youd ever need for the time being, and it has speakers built in. but they may sound like crap. Overall, I really loved having the monitors.

    They are the best looking and best picture I think you can get at this price. But both of mine have eventually found their way back to Monoprice for the screen flicker the seemingly only plagues me through the use of any of my computers. The image gets scrambled after a few minutes of use and the images go all over the place.

    Cheap, but not a good value. Mine broke.

    Pros: Cheap, Good looking screen. Cheap. Non-glare screen

    Cons: No cross-ship on warranty replacements. New model doesn't have the base that can rotate to portrait orientation. My unit failed.

    I respect what Monoprice is trying to do here in offering the cheapest 4k monitor on the market. If you go into it with that in mind, you can keep your expectations very low. I bought 1, then liking it I bought a second. The second one was a different model without the rotating stand and with a matt finish screen rather than glossy. The screen is better, the stand is worse. Then, the first one started having problems booting up where the backlight would come on, but it took several minutes of fragmented video before the full screen would appear. Being the cheapest 4k on the planet, cross-ship replacement is not an option from Monoprice. I had to do without one monitor for 10 days. Not big problem when I have multiple monitors, but if this is your only monitor, not a very nice arrangement. HP and Dell cross-ship replacement monitors. I buy monitors for a mid-sized business, and I probably won't be buying any more of these. I don't need the trouble just to save a few bucks.

    Read the Reviews, then pony up your dough

    Pros: Wonderful display rich colors with no variations around the screen. Solid blacks.
    Well supported by my preferred video cards (NVidia) and Mac. MacBook Pro mid 2014.
    Base is solid and steady not as shaky as some reviewers reported

    Cons: Would have preferred a 16:10 display, but that is my preference and well understood prior to purchase.
    Speakers are not great, but all of the reviews warned me about this.
    External Power brick, but again, I knew that
    4K/60Hz only available via Display Port (again, well documented prior to purchase)

    This review is based on my experience with my display: I reference other reviews from the introduction of the monitor, and I am not nay-saying the writers of those. My experiences are what I am seeing.
    I looked at this monitor and the growing pile of user and published reviews. When I was ready to try it out, they were out of stock for about 2-3 months, so I had to wait quite a bit more. But they finally arrived mid-August 2015 and I waved my plastic and it appeared in 4 days.
    It took me a week or two to find time to unbox it and cable it up. At first it took a bit of time to get the audio working ( and was disappointed that the reviews were correct: it is tinny and not great, but I did not grade this lower on that account). The brightness of the screen, in my dark basement lab, was overpowering. I dialed back the brightness and it works much better. The glossy finish of the display is also not my favorite choice, but by managing light sources and angles it can be controlled.
    The color for my photos, games and work is great: bright colors and solid blacks is good and there are no bad pixels on this display.
    The ability to easily make this a portrait display is great: I have an old Gateway 24" monitor that did that (10 years ago) and have always loved that ability to see things page-size (or even more).
    I am currently using the included base: I have it on a good solid table and it isn't at all jiggly or weak for holding the display. I do plan to migrate this to a wall-mounted system before long, so I can set and leave multiple monitors, but as a desktop it is good.
    In all, this is a cost and feature competitive display definitely worth considering if you are looking for a dense pixel display. I have seen some better ones, but they came at higher costs. Like every purchase I have made from Monoprice, I leave the transaction satisfied and with good quality gear. I began purchasing cables, and now I am buying bigger ticket items: I like the variety Monoprice presents and will keep up with their work.

    Good price with some defects

    • J.A,

    Pros: + Best price for 4k
    + Stand is sturdy enough for most orientations

    Cons: - Uneven splotchy brightness on the bottom of my monitor
    - reflection is like a mirror and very distracting during the day

    I really wanted to like this monitor and after using it for 1 month I can give an honest assessment.

    The first thing I noticed while looking at a black picture to test the brightness was uneven splotches of white light near the bottom, they are very noticeable when looking at a darker picture or movie. It seems like a manufacturing defect on my monitor.

    The 2nd issue is the extreme amount of reflection of the glass screen on the monitor, if you have a light source anywhere behind you when using this monitor it will reflect it perfectly, I have to shut my blinds and crank up the brightness to the max in order to use this monitor effectively.

    Other than these 2 major issues this is a decent monitor
    It has a quality stand and can display portrait or landscape if need be
    I wasn't wowed by the colors but did appreciate the extra screen real estate that comes with 4k

    I read reviews for this monitor before I bought it and was expecting the reflection but not the defect with splotchy brightness.

    Hi J.A.,

    Thank you for your review on PID 12156. If I may ask, are you able to send me pictures of the "splotchy brightness" issues mentioned above? Please let me know as I will be forwarding this to our product team for further review. My apologies for the trouble and thank you in advance!

    I just sent a picture to your inbox

    by Monoprice Administrator
    Thank you very much. I received your email with the picture and have to say that those splotches are pretty extreme. This is the first time I have personally seen this issue and it definitely looks like you received a defective unit. I can assist you in setting up an RMA for a replacement, if you would like. This monitor comes with a one year warranty and it would be of no additional cost to obtain the replacement as we will cover shipping costs both ways. If you would like to proceed, please let me know and I will get that started. I am truly sorry that this happened and I hope this helps.

    That would be great, I would like to move forward with the RMA.
