    *** 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.

    Works great with Apple (using appropriate adapter)
    I know this monitor sells with the notice that it is not compatible with Apple computers. However I didn't believe this and I was determined to make it work with my MacBook Pro without having to spend the money on a real apple. True, out of the box the monitor is not fully compatible with macs running MiniDisplay port or Thunderbolt. Apple has inexpensive Mini DisplayPort adapters to work with DVI. I had one of these handy and I tried to make the monitor work. It did, however it maxed out at 1920x1080. This wasn't going to work for me since I was after the native resolution of 2560x1440. Anything less was unacceptable.

    After a little bit of research and digging I found out that the reason the monitor won't work with the basic Mini DisplayPort adapters is because they don't have enough power to manage the video conversion necessary for the higher resolution. From there I found out that apple makes (a very expensive) Mini DisplayPort to DVI adapter that is powered additionally by USB. I had to pick this up at my closest apple store an hour drive away since none of the local stores carried the more expensive adapter. After I got back home and hooked everything up, it worked. I was so excited to have full resolution support. I ran into a problem where the display started to turn off and on. I thought.. "oh gosh.. this is not going to work out after all..." But in the end, a simple restart was all that was needed to reinitialize and redetect the monitor. (I had originally hooked it up while the computer was already running). After the reboot it worked perfectly and has continued to work perfectly for months. A+ monitor minus the 1 dead pixel out of the box.

    Using a mid 2009 17" MacBook Pro with (Monoprice 27" IPS display + USB Powered Mini DisplayPort to DVI adapter)

    PROS: Amazing picture. Super thin. Pretty sturdy. Works perfectly with Apple computers using ONLY the POWERED MiniDisplay Port to DVI adapter.

    CONS: No HDMI. Not natively display port or thunderbolt compatible.

    Are you feeling lucky?
    I just received this monitor last night, and it's not working correctly out of box. I knew it wasn’t my setup because I had my neighbor buddy bring over his monitor and it worked perfectly and immediately at full 2560 x 1440, using my own DVI-DL cable, and even the cable that came with the Monoprice monitor.

    Being tech savvy and really wanting to get this thing to work, I didn’t give up and pushed forward, trying everything from using DDU and CRU to remove graphics drivers and monitor configurations, to alternate computers and video cards, including my neighbors. After trying all the logical troubleshooting and brute forcing to no avail, I tried something unconventional…

    Performing a raindance and human sacrifice simultaneously to the Monoprice gods while power-cycling the monitor / computer as a shooting star passed overhead, I was presented by full 1440p resolution and all its glory. It reminded me of that moment when Clark Griswold finally plugged in the Christmas lights at just the right time, and hallelujah!! There was light.

    I couldn't believe it finally worked! It was beautiful. But at the same time I was deeply saddened by the sinking feeling that it was only temporary. That all this work would be short-lived, and if I let my computer go to sleep, the monitor would never wake up. After all, there was no logical reason for it to have worked in the first place. It was random. The PSU decided after enough cycling to push the amount of power that was needed to display the full native resolution. And alas, I was right. I woke up this morning to the monitor exhibiting the same symptoms as the night before. Only this time I’m not going to waste 2+ hours and another brother’s dear life going through the same ritual in hopes of getting the picture again.

    Now I have to request a replacement or refund, and not sure what I want at the moment. For the few hours I got to play with it last night before going to sleep, the picture was beautiful, and there were 0 dead pixels. After having a taste of seeing my code on this display, and being able to see so many lines of it at once, while having the debugger and console on screen too, I just can’t go back to a 1080p display.

    Update: Before submitting this review, I decided to shop around some more, and ended up purchasing a totally different even more beautiful, albeit more expensive monitor with warranty somewhere else. I think I’ll stick to Monoprice for purely cabling needs from now on, and spend the extra money to likely not have to go through this again. ( I was so excited about this Monoprice monitor arriving I even left work early to be home when it got there. )

    TLDR: If you’re looking for a beautiful AND quality display that will last, and just work out of box at its native resolution, then don’t get this monitor.

    If you’re feeling lucky, and want to play the monitor lottery (dead pixels is the least of your worries), endure the torture of waiting, and risk the heart-breaking disappointment of finding out you weren’t a lucky winner of a gorgeous working display, then look no further. The display is beautiful and may be worth the price if it works. Though based on my experience and that of others, it may not work for long.

    PROS: Beautiful display with great color accuracy and enough resolution to have a lot more window panes visible right in front of you.

    Great for development work.

    CONS: Dead pixels are the least of your worries in this monitor lottery.

    Button controls are clunky, unintuitive (Source = CONFIRM??), and pressing them feels like I'm pressing a button that was made in the 70's. Not to mention their horrible placement.

    You may end up with a feeling of regret, and wonder if you should have just spent an extra few bucks and bought something better. Read the reviews here. I didn't want to read anything bad about it, but I regret that now. I just looked at the price and the amount of stars...

    Missing parts
    Shipped missing parts, tech support told me to take the monitor to the hardware store and try out different parts. two reps later they finally agreed to send me the bolts, but i have to wait three days to get them. Monoprice unable to just tell me what bolts they are so i can go buy them. Overall not sure that saving money on this versus an apple cinema display was entirely worth the hassle.

    PROS: Display looks great

    CONS: Missing parts

    IMPORTANT NOTE: This monitor has a pixel clock of 241.5MHz. Anything above 165 will require a dual-link DVI connection for maximum resolution! Otherwise your resolution should top out at 1920x1080.

    This monitor is leaps and bounds ahead of the competition concerning price and mass production build quality. Gone are the days of grey market screens on auction sites for those of us who get angry when we think about how stagnant the pixel race got after 1080 became "HD"

    This monitor is a game-changer. Competition is back, and Monoprice customer service and their line of monitors is more than ready for the challenge!

    PROS: No better value on the market.
    Beats out contrast quality on existing iMacs in side-by-side comparison.
    Metal case?! Why aren't more companies doing this?

    CONS: Dual-Link DVI required.
    Monitor stand hurts the finished product.
    Not a monitor you want to see the back of.
    In a perfect world, it would have more ports on the back.

    Great monitor at a great price! Highly recommended!
    I just received this monitor today and have been using it for a few hours now and I was compelled to write a review. I had hesitations about this monitor, esp one at this price. But as soon as I turned it on, all my worries disappeared instantly. This screen is beautiful and looks perfect. No dead pixels that I can see. The single piece, edge to edge glass makes everything pop and I suspect this panel was originally meant for a 27" iMac (there's a small unpainted area up top in the middle of the frame for a webcam and the rounded top corners and squared off glass bottom looks like the same layout as an iMac's). Text is sharp and photos look great on it.

    There is some backlight bleeding on the bottom and right edges that only is visible when viewing a solid black image. Otherwise it's undetectable.

    Only other issue I have with this monitor is the basic stand. Ended up connecting it to an ergotron monitor arm and it's now perfectly situated at my eye level. The monitor only weighs 15lbs so you don't need a heavy duty stand for it.

    Using a radeon 6770 via dual-link dvi to drive this monitor on windows 7. Overall, this monitor is highly recommended and wouldn't hesitate to buy another one.

    PROS: Glossy screen but isn't too reflective, no dead pixels. Light weight. Colors and text pop on it.

    CONS: some backlight bleeding on the bottom and right edges. osd controls take some getting used, included stand could be better.

    Great Monitor, Lousy Cable
    This is a preliminary review as I have yet to see the monitor working in full resolution (2560x1440). The Dual Link DVI-D cable included with the monitor is not working correctly. I have the monitor connected to a Nvidia Quadro K620 Graphics card and the monitor resolution is maxed out at 1920x1080. Anything above that does not display. Monoprice has RMA'd the cable and I should receive it next week. Hopefully it will solve my issue and I will update my review then.

    PROS: Great price

    Good colors

    Easy set-up

    Packed well for shipping

    Zero dead pixels

    CONS: Buttons on back is kind of annoying

    DVI cable included is garbage

    lacks DisplayPort

    Response from Monoprice
    I would like to change my rating of this monitor from 5/10 to 7/10. I received a working DVI cable from Monoprice and the monitor is now working at full resolution. A great monitor for the price.

    Great panels, but inconsistent
    I ordered two of these panels and for the most part love them. I have them in a multi montior setup, which makes the rear controls a bit hard to use on the left-most panel (since the controls are on the right.) I mainly let the system put them in standby.

    The external power supply is a nice touch since the PS is usually what dies first. Knowing, theoretically, I can replace it down the road does offer some piece of mind. That said, one of the two supply's build quality is pretty shoddy. The case opens a bit and the cord is fussy to keep power going to the display. It lives in a wire management cage under my desk so it's not a huge issue.

    The biggest problem I've had is one of the two panels exhibits image retention issues. This is most noticeable when rebooting Windows 8. The "restarting..." screen which is normally a solid blue shows remnants of the windows on it. I also recently noticed it while watching a video full screen, the windows present on the screen were ghosted in the video during dark passages. I'm mainly doing development on this machine, so it doesn't effect me too much.

    Overall, these are a super great buy for the price and would recommend them, but know what you're getting into.

    PROS: Bright, thin, IPS panel, price is right if you hit a sale, external power supply

    CONS: Image retention, rear controls, large bezels

    First Glance
    Would be a fantastic monitor if it didn't have so much bleeding. But for other applications where the screen is not black, monitor will do just fine. If you care about watching movies, avoid this monitor. But if you don't watch movies or have another output for watching movies, then this is a decent deal given the price.

    PROS: price is good
    thin and relatively light

    CONS: Poor black levels, backlight bleeding around all edges

    When the screen is black, you get a ton of backlight bleeding around the edges. Monitor is horrible for movie watching.

    2 Strikes...
    I'd love to review this monitor but I now have 2 broken ones sitting here. And of course it is now out of stock so either I wait or I order from someone else and wait...

    The first one turns on but there is no video at all.

    This is the first thing I have purchased from Monoprice. Not looking good for repeat business.

    PROS: Looks nice

    CONS: First one was DOA, second one was physically damaged but the packaging didn't appear to have been handled as roughly as the damage indicated. Possibly a packaging issue.

    Great value
    This monitor is an incredible value for the price. On a totally black screen, you get a lot of backlight bleeding around the edges, so I wouldn't recommend using it as a video monitor for watching movies (you will never notice it in typical computer use), but other than that the picture is great. The base connection is a bit weak even with it tightened as much as I can manage, it lets the monitor tilt a bit over time, but it isn't a big deal. I didn't have to adjust it much to get the calibration right - the 6500K color temperature setting was pretty close to ideal out of the box, which is better than most monitors I have worked with.

    PROS: Price, decent calibration out of the box, crisp output, no dead pixels

    CONS: Base mounting is weak, poor black levels, backlight bleeding
