    Goldilocks OLED Ultrawide.

    Written February 2026 for the 39” 1440p 240hz model, in White colorway for $800 US on a 50% off sale. Why 4 stars and not 5? Well, youve just gotta know what youre getting here and temper your expectations. If you think this is the end all be all perfect monitor, you might have your hopes too high. Theres a reason it was 50% off when I bought it, there are newer panels coming out this year that are pretty insane. However, if you think this might be the perfect large screen OLED ultrawide so as not to have too low of a PPI like the 45”, but larger (and more importantly taller) than a 34” ultrawide, you might be onto something. If youre looking for perfect text clarity as well as high framerate ultrawide oled gaming, you might be disappointed by the text clairty, but not necessarily the gaming performance. This monitor is a great balance between saturating my 5070 GPU at 1440p ultrawide 240hz without leaving either frames or resolution on the table if you opt for the new 5K2K, which im not even sure can be saturated by a 5090. Guess it depends on which games you play. But for me, this 39” monitor strikes a great balance, especially on sale ($800 US in Jan 2026).

    Immersive Experience

    Overall a beautiful monitor. One thing that was not really mentioned anywhere is VRR Flicker on OLED Panels (look into it if your thinking of buying OLED and no it’s not specific to this monitor). Other than that, this monitor is amazing.

    Great display, but….

    I wish it was desk/wall mount available and that it had better height adjustment options. Other than that, it’s great

    Solid all around computer monitor

    All around very pleased with this monitor. However, I feel like the LG software is too much to handle as sometimes i'm having to restart it because it has issues matching the FPS that the game is outputting. When it comes to streaming directly from the monitor, it is great but it's not a smart TV (though it can be and LG set it to be). I wish the configuration was easier but good looking monitor. Great size. Sturdy. Nice and bright. Everything else outside of the gaming arena is excellent but again, matching the game to PC to monitor is stressful on this if you're managing a lot of output which is the exact reason you get something at this price point. If you have the money, buy it. If you're looking to pinch a few dollars then I understand and there's smaller more direct monitors that do just as good if not better.
