If you’re reading this, you’re likely going through the same decision making process I was, is it time to make the step up to 4k 144hz or go another handful of years at 1440p for the high refresh. The big fear being, can you actually use the extra hz at such a high resolution. Well, what I’m going to tell you is, if you have the graphics horsepower then it absolutely is finally the time to make the leap. How much horsepower is enough? 3080/3090 would be the target. If you’re packing less than that, 1440p may be the better option for you.First, lets start with the color on this thing. The picture on this POPS. Probably the best color I’ve seen on a gaming monitor under the $1000 mark. It’s bright, it’s accurate, best of all it looks great without calibration. Right out of the box. So even the no fuss/plug in play group will be quite happy with this model. It is easily accurate enough for photo/video editing. HDR also looks good on this screen, but not quite to the level of FALD monitors—but, it’s hard to fault it there considering you aren’t paying FALD pricing that is easily 2-3x the price and has hurdles to leap just to get 144hz out of it. Being an IPS, the contrast ratio isn’t great, and blacks can end up looking slightly grey due to that, but it isn’t terrible either. It’s an IPS, anyone looking at an IPS knows what to expect in this regard.Of course, people looking at this are likely here to ask about how it is for gaming. My response? It’s perfection. Ghosting isn’t an issue, even in high speed titles, while slower paced titles don’t show any signs of overshoot. Just leave the response time set to fast and forget about it, that setting will work for everything. Just make sure you have some serious GPU grunt backing it up or you’ll find yourself lowering the settings or dropping the resolution. Speaking of which: if you do drop the resolution, the monitor does a very good job of scaling the image—so it isn’t the end of the world should you find yourself slightly outgunned by a newer title. I personally am running this with a 3090 backing it up and it is a match made in heaven. The gsync compatibility works perfectly, and the input lag is way under 1 frame.I also feel I should talk about the RGB light ring. Lets be honest here, RGB is a feature that you either love or you hate. People who like it have it on everything for their rig, and people who hate it make it well known. For this monitor, the RGB is very well done. I’m a big fan of the ability to have it sync with whatever video is on the screen. It does seem to lag behind the picture by a small amount, but it isn’t too bad and you only notice that fact if a scene goes dark to light very quickly. It works as an excellent bias light for late night gaming. The RGB at maximum settings is bright, we’re talking it glows with the fury of a thousand suns. I wish it had more options, but if you are on the side of the fence that enjoys RGBs then you will love this.I do have one qualm with this monitor, and anyone who’s reading this probably knows what that is: The local dimming feature. The local dimming, being edgelit with only 16 zones, is not a great implementation. It works, but it leaves very noticeable streaking in the zone if the area above or below the bright highlight is dark. IMO it is best to leave that feature off for this reason. LG could have shaved the price on this unit $100 and just left that out, because it is perfection without it. I’m not taking a point away for this because it can easily be disabled.All in all, I am quite happy with this monitor. One of the first monitors to actually manage 144hz on a 4k screen in 10bit color mode with HDR running without chromatic sampling, and it does so at a very solid price point.[Note: this monitor can overclock to 160hz with the firmware update, and my model can maintain that 160hz. I am scoring this monitor as if it couldn’t though, because there are likely panels that will not reach that speed.]

First, I need to point out that this is my first 4k monitor (switched from 1080p finally), so I may have quite the biased opinion as it is my first 4k gaming experience. I have had the monitor for about a week now and have found zero issues with it. I paired this monitor with an RTX 3080 FE, and it runs beautifully. Setting up G-Sync on the monitor was super easy, as you just have to flip it on in the settings (I haven’t touched any other settings on the monitor), and check the Nvidia Control Panel to ensure that G-sync is on (it auto-detected and set it without any input). I believe the G-sync is my favorite feature, as all of my games are buttery smooth, including Microsoft Flight Simulator. I wish I could comment more on the color quality, but I am coming from a basic 1080p monitor and really have nothing for which to compare. I think the monitor was well worth the money, and while I don’t care about having RGB lights on a monitor, they are super cool nonetheless. Below, I will list some notes on the monitor so I don’t sit and babble mindlessly.Pros:-4K and 144Hz refresh rate-G-sync Compatible (do some research and you will likely find that compatible monitors work just as well as ones with full G-sync chips/G-sync Ultimate etc)-RGB light ring on the back…. Its really cool to see the light ring glowing in the back, and has some profiles to change them to your liking, if that’s your thing. Personally I no longer care about circus lights.-Beautiful colors and screen quality (my opinion of course)-Did not find a single dead pixel-Did not observe any IPS bleed ( basically a smoky white glare on corners of some IPS monitors in dark scenes)-Stand allows a good amount of options for positioning-Easy to set upCons:-Watch out for the height and depth of the stand. It does adjust up and down, but the lowest position is still higher than I expected. It fit in my space by little more than 1/4 inch height wise. The stand sits back pretty far from the screen, and the legs jut forward quite a bit. (Ill update with the actual dimensions when I get a chance)-no HDMI 2.1. This is a very new technology and I don’t care because the latest Display ports allow for the max performance of this monitor. Bottom line here is that unless you were planning to hook this up to a PS5 or Xbox Series X, this doesn’t matter at all really, unless you absolutely insist on HDMI, in which case dont expect 144HZ at 4k and that’s a limitation of HDMI 2.0, not the monitor.Other considerations: Look up the actual dimensions of the monitor including the stand to make sure it will fit well in your space, or be prepared to use VESA wall mounts.. I was a bit surprised by how much total depth the monitor took up.Do yourself a favor and pair this with a high end GPU. A pretty screen and high refresh rate isn’t of much useful value if you can’t feed it.HDR 600?? I haven’t tested the HDR at all, nor do I really care to. I’m not impressed by HDR in its current implementation by game developers (or maybe I have just never seen an HDR 1000 fancy pants monitor perform), so I don’t think I will ever turn it on.. I will say though, if its your thing you should look at other reviews for that info, but be prepared to pay a STEEP premium for the latest in HDR tech.Overall, you get what you pay for, and for the combination of the product’s quality, specs, and features, appearance, and performance, I believe this monitor is the best you are going to find under 1k, at least through all of my research.

I originally purchased an LG UltraFine panel that had significant light bleed in both bottom corners. I ultimately returned it. Thinking that perhaps the $150 extra on this panel would get me better quality control, I bought this panel.Unfortunately, while the light bleed in the bottom corners of this panel isn’t quite as pronounced, it’s still present and sometimes distract in darker scenes. It’s almost like the bottom corners of both panels were slightly warped back, or possibly that the center of both panels bulged outward slightly. Either way, it speaks to some poor quality control on LG’s part, something that a Google search has informed me is pretty common these days. Their OLED panels are amazing (I have one), but it seems their LCD panels aren’t anywhere near the same.
