    *** NEWS FLASH! ***

    If you're a serious gamer or professional graphic artist, you need a seriously good monitor and you won't find much better than this 27" IPS-ZERO-G Monitor from Monoprice!

    The heart of this monitor is the brilliant display panel made by LG. This panel features a maximum brightness level of 440cd/m², a tight 2560x1440 maximum resolution, and up to 80,000:1 dynamic contrast ratio. It features a 178° viewing angle in both the horizontal and vertical planes. The monitor is primarily intended for use with the Dual Link DVI-D interface, but a VGA interface is included as a backup.

    The display is housed in an ultra-thin bezel with a glossy glass, anti-glare laminate that extends to the very edge of the bezel, for a clean, modern appearance. Responding to criticisms monitor's casing, we've upgrade it to an all metal case. The fixed plastic stand was replaced with a heavy-duty metal reinforced stand, which can be detached by removing a single screw. The monitor also sports a 100x100 VESA mounting pattern, making it compatible with most wall and desk mounts.

    We also improved the interface to the monitor in two ways. First, we moved the connectors from the bottom of the panel, which offered too little room for maneuver, to the side, which makes it much easier to see and access the connections. We also improved the menu control buttons by making them larger, with greater spacing, and made the power button a different shape so that it is easy to distinguish by feel alone.

    We are standing behind this monitor with a 5-dead-pixel warranty for a period of one (1) year from the date of purchase. If you can count five dead pixels, we'll send you a replacement.

    Too cheap and non-durable

    • Anonymous,

    Pros: Cheap
    Acceptable display when it works.

    Cons: Low quality - white blur around edges.
    Broke inexplicably after 2 years.
    Flimsy stand.
    Few connector options.
    Controls on screen not very useful.

    I bought this about 2 years ago now because I wanted a nice big screen, but didn't want to shell out for a Thunderbolt. Regretting that now.

    About a week ago the screen just stopped working. It still gets power, my laptop still recognizes it, but it won't actually display anything. Critically, even the menu and source buttons on the rear don't cause any display action - it's just blank.

    Adding in the thunderbolt to DVI adapter I had to buy, and the better stand (it comes with a flimsy plastic one), this cost me about half a thunderbolt, but only worked for two years. So, perhaps not a good deal.

    The included DVI cable was completely defective right out of the box! I plugged in the monitor and couldn't figure out why it just wasn't working at all, and then tried a different DVI cable and it worked. Looks like another reviewer had a defective cable too - this is crazy. Monoprice is a cable company - you guys should definitely be sending working cables with brand new items! Can you please send me a working cable?

    For what it's worth, the monitor looks ok with my other cable, but i can't really tell bc the cable is so short i have it on the floor and it is not really useable.

I see you already have an RMA in place to get the cable replaced. Thank you for bringing this to our attention as well as for your feedback, we truly appreciate it.

    Beautiful monitor, with a sharp screen

    • Anonymous,

    Pros: This thing is gorgeous, and it makes everything I do on a PC look better.

    Cons: - Malfunctioned after 1 month, but Monoprice immediately RMA'd it at their expense

    - The new monitor came with a bad Dual-Link DVI cable. I am sure Monoprice will send me a new cable quickly.

    I am a home power-user and a hardcore gamer. This monitor is crisp, clear, and looks good doing it.

Thank you for bringing this to our attention and hope this helps!

    Very Disappointed

    • Peter Brambs,

    Pros: - Nice display in low resolution mode.

    Cons: - Won't come up after iMac comes out of sleep. Need to cycle power.
    - Monitor stand was damaged.
    - Could not get the monitor to work in high resolution with the Monoprice mini display port to Dual DVI adapter.
    - Cannot speak to a human for support. Chat only.

    I was very disappointed when I received the monitor. The stand adapter was broken at the base of the monitor. That was not a show stopper because I was going to put it on a VESA Mount. I'm using with this with an iMac 27 and had to purchase a Display port to dual DVI adapter in order to get the full resolution of the monitor. I could not get it to work. I was able to get it to work in single DVI mode (low resolution only). The display looked nice in this mode but when the computer went to sleep and came back, the display remained black. On occasion, it would come up properly. I was told that this is normal. Really?? Not being able to speak to support was incredibly annoying. I had to trouble shoot the issue using a chat screen. Again... Really?? In conclusion, I really wanted this monitor to work. They are sending me a new adapter and I have a few weeks to try to get this to work before I have to return the monitor. I'm afraid a return is inevitable.

    Great monitors - DVI-D cable issues

    • Akshay,

    • 5/17/2015 2:23:53 PM

    Pros: Great monitors - looks good, great size, great quality

    Cons: Low quality DVI-D cables

    DVI-D cables out of the box gave us problems when connecting to a Mini display port to DVI-d adapter. My set up was a Macbook Pro Mini display ports to DVI adapter 2 of these monitors. Experienced horrible flickering and couldnt use at all. Went to local Staples and bought DVI-D cables to test and worked great.
    Do yourself a favor and order some quality DVI-D cables and replace the ones you use to remove flickering.
