    The quality is not good

    Thank you Revain for understanding that I didn't like the quality so I returned it. I spent more money and am getting the best. I just hooked it up for a few minutes and compared it to another LG LED I've had for 5 years and this 27EA63 looks much better and clearer.

    Nice simple monitor

    Since I only use these monitors (I bought two) for teaching via Zoom, they work absolutely flawlessly. There were other monitors of the same size for a little less money but I didn't know the brand so I chose LG as I have two other LG monitors for my home.

    Strong yellow cast and color wash

    The monitor works fine, but only when I change the color settings with my graphics card software to change the color temperature to cool. None of the monitor settings seem to solve the problem of a noticeable yellow cast in the colors (see photo, where the monitor on the left has a richer yellow than on the right). I couldn't recommend this monitor without graphics card software. It has many useful features like a headphone jack and AMD Freesync, but doesn't require any third-party software…

    When I'm sitting next to a 27-inch BenQ monitor that I bought a few years ago, the picture quality isn't as sharp. I'm honestly a little disappointed, but it does the job.

    Excellent monitor in my review

    I bought 4 of these for a commercial application to view security camera feeds. They worked great, they are light and strong. The picture is bright and clear. You were lonely to connect and look great.

    • The monitor is difficult to set up.

    You need to reduce the brightness A LOT

    Got this through a local big box over the NO TAX weekend. I have to say I almost took it back because it was so bright I didn't think I could make it work. Here's what I ended up finding: Don't install any drivers at first. Second, use your graphics card settings to reduce the brightness. Then use the small joystick under the LG logo to fine-tune. This joystick is great once you learn how to use it. It took a while, but I finally got 75 fps - an improvement over 60 fps for gaming on a 27-inch…

    The best deal I've found! the best in my rating

    I'm not qualified to judge monitors, but this one looks good to me. And he's so big! My graphics card isn't FreeSync compatible, so I can't comment on that. Although good packaging and fast delivery.

    • Limited Customer Support

    Revainrating 4 out of 5

    Inexpensive device, works great.

    Really good for the price. Looks great and works great with my ultra wide angle lens. It's a bit dimmer than my main display, but is rarely used apart from watching Youtube videos in raids or discord. I love the LG Nubby joystick and the menus work fantastic. Not many features, but they're not needed on a display like this either. It doesn't weigh that much so sits securely on the monitor arm. HDMI ONLY. I wish it had DisplayPort. I didn't get it at first and I already have an HDMI connection…

    What a pixelated mess on the monitor.

    I enjoyed it the most and thought to myself "I don't have to double my spending just to buy 4k, after all who can really tell the difference?" I was wrong and now I have half the money for this disappointing one Monitor lost on top of that. Everything about this monitor is just poor quality, I wouldn't even call it mediocre. In fact, after over an hour of fiddling with the settings and applying the blue light filters, the image is STILL as awful as it came out of the box and somehow still…
