The monitor looks great and is of sound quality. The base plate is heavy, thick metal, and the monitor itself is also a little heavy. Not in a bad way, but in a quality way. It feels solid and well built. No dead "pixels" or anything like that.The monitor is easy to move (slide) up and down and it does tilt to and fro, and it also pivots left and right. Due to the weight of the base plate, you can practically move it around with one hand. Again, a good quality feel to it.I like the fact that it has built in speakers so I can stream TV movies and news shows without the need for a sound bar or e

Picture quality is unbelievable, hands down the best picture quality monitor or TV I’ve ever owned.I bought this to replace a 27-inch and 22-inch Acer setup that I had been using for 6+ years, and this was a MAJOR upgrade. Those monitors were fine, but pretty bland by today’s standards. Considering I work 10–12 hour days and also game and watch media regularly, I figured this was worth the investment.Out of the box, setup was incredibly easy. Everything clicks together nicely and just feels well built. The settings are also surprisingly good right away. What’s really cool is that the monitor a
Great 1440P OLED monitor, I would always highly recommend LG for their great picture quality. Disclaimer that with this and most OLED ultra wides that you will more than likely have to run an OLED cleanup as soon as it is out of the box and every now and then.
The monitor constantly turns itself off despite disabling most features including power saving and degrading the mhz to a much lower capability than my system can handle. Tech support just sent me into a circle of what I had already troubleshot. Updating drivers for gpu and monitor didn’t help. Researching forums, this appears to be a common issue across several models that I wish I had known about. I’d suggest looking at alternative solutions.
Quite curved at first, but then never noticed it again after using it! It’s fantastic. I turned down the brightness quite a bit.. same resolution as my old LG 34 inch that was nine years old. But being it’s bigger and OLED so a little crisper., I don’t have to wear my computer glasses anymore!!! did not expect this so I am thrilled. I will always buy LG monitors.
I purchased this as an upgrade for my boss, and it did not disappoint.The OLED display is stunning—colors are vibrant, the picture is incredibly sharp, and the curved design really enhances the overall experience. Everything runs smoothly, and it just feels like a high-end, premium monitor.He’s been very happy with it, which says everything.Great choice if you’re looking for top-tier quality and performance.
The curve on this monitor is NOT bad at all. It’s been called “severe” among other things, but I use this as a daily monitor for work, streaming, some gaming, etc. so it’s all over the place on use cases. It was a noticeable improvement over a 32” monitor, and the added width makes a big difference (no pun intended). The DPI of 96 isn’t razor-sharp, but I’m not 4 inches from it looking for soft edges or gotcha disappointments. It’s fine so don’t worry about it. The text quality is as good as most others, and frankly isn’t a problem at all. If a pure text-displaying microfont monitor capable of
I love this monitor. I switched to this from a dual monitor setup with displays provided by my company (27" 60hz). The difference is unbelievable. The clarity is great, it's super easy to snap windows to each side of my screen to be efficient at work while also having a big and immersive picture for videos and games. I haven't done any benchmarking to see how accurate the colors are, etc., but overall it has been great in the first week.BTW, the listing didn't mention this, but this monitor has a built in speaker that is acceptable if you're not an audiophile. It also has "rgb" lighting on the
