    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.

    Mediocre performance and support

    Pros: Cheap price

    Cons: Cheap quality and support

    Display is of decent quality. Not the sharpest display and backlight performance is ok. There are definitely hot spots and cold spots with backlighting and the dynamic contrast is borderline distracting how much it corrects.
    Display has a foreign object on the inside of the glass and when support was contacted they explained I would have to ship the item back first before a new one would be shipped. I am surprised that an option for an express shipment is not possible and there was very little empathy from the customer service rep. Being that this is ordered for a business, I was surprised with how rigid the rep was.

    Ok for the price

    Pros: Good value for price
    Just right dpi (my opinion)

    Cons: One stuck pixel
    Two pieces of dirt under glass
    Speaker is marginal at best

    Good value, would have been great except for the one dead pixel. Careful during unboxing not to overlook the small screws for the stand.

    Great panel but supporting cast not so great.

    Pros: Good color and viewing angles, no dead pixels. Good controls.

    Cons: Poor upscaler. Speakers of last resort. Sometimes goes to sleep and refuses to wake up.

    The viewing angle and color fidelity of this TN-panel is great. No dead pixels on my unit and colors look good. The on-screen menus have a lot of information and controls which I like to have available, even though I rarely touch the menus after initial setup.

    I was not able to sustain 60Hz on my unit. I'm not going to blame the monitor as it could be the DisplayPort cable or the video card. Attempts to run 4K @ 60Hz would produce a lot of video glitching and errors, eventually something (video card driver?) would give up and degrade to 4K @ 30Hz and it's silky smooth from there on out. 30Hz is acceptable for my purposes, but keep this in mind if you are looking at this unit for the advertised 60Hz capability.

    For completeness, some of the other minor idiosyncrasies I've had to deal with:

    (1) Scaler. ALWAYS run this monitor at native 4K resolution, because otherwise the built-in resolution upscaler kicks in and it renders strange visual artifacts all over the place. The rectangle where the on-screen menu comes up? Sometimes that area is rendered a frame behind than the rest of the screen. (!?) Game players who want better frame rate will need to turn down their graphic detail, because running at lower resolution is not a viable option.

    (2) Standby: After going into standby ~10 times, it will no longer wake back up. Even the power button does nothing, it has to be disconnected from power to be reset. Workaround: plug it into a power strip, and use the switch on the power strip.

    (3) Backlight. It is not totally even, with blotches of tiny-bit-brighter near the center of the screen. But it's even enough I only notice when the screen is completely black. All-black rarely happens in my usage so it doesn't bother me much.

    (4) Speakers. For an office PC where the only audio that needs to be heard is an error beep, it is fine. The quality is too poor for anything else. Use headphones or external speakers.

    One year of use and happy

    Pros: Great base, perfect 4k resolution, HDMI audio, deep black screen becomes reflective with no signal input

    Cons: deep black screen becomes reflective with no signal input

    I have been using this monitor with a macbook pro and the 4k quality is great. People cannot read what is on my screen from 3 feet away. The most common thing people ask me is how can you see that, because they are not used to seeing 4k resolution. I quickly adjusted to the tight 4k resolution and smaller text size.

    Fantastic Monitor with some small quirks

    • Direct,

    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. :)
