Not a fan of the AI features - Great monitor size, crazy expensive at 1.6k but it went on sale shortly after i bought it and got 600 back so over all still expensive. Im not a fan of the tv/AI features, as this is only used as a monitor for me. Main issue is it constantly wants to restart and calibrate, like once a day, and it doesnt gove the option to turn this feature off. Another issue is it doesnt have a way to turn off blutooth so its constantly sharing my info to LG as it was recently discovered... Overall great monitor!

Customer reviews
Write a reviewAmazing monitor! - Best mont I’ve ever seen hands-down. I would recommend it to anybody.
Amazing - The graphicsOn the LV curve screen are amazing. It brings playing an online game to life.
Great Gaming Monitor - So far I'm loving the LG monitor. Mainly using it for gaming but it doubles as a smart tv. Watched the recent bears vs patriots game and the quality was fantastic. The curved screen is a nice touch when gaming at a closer distance, but viewing from too far away might seem a bit distorted. Great for 1 or 2 people to watch stright ahead, but groups of people watching a sports game or movie might not be ideal due to the curve distoration at differnt angles. All in all one of the best purchases for a gaming PC.
Best gaming monitor - fast response time for great motion handling is beneficial for playing action games. Low input lag
A Beast Monitor - The LG UltraGear 45-inch OLED takes gaming to another level. Stunning colors, deep blacks, buttery-smooth 240Hz performance, and a massive curved display make every game feel immersive. This isn’t just a monitor — it’s a whole new gaming experience!

Amazing picture - I use this for pc gaming with a rtx4070 super. I originally wanted the 39" because i was worried about the curve on the 45" but they were sold out. I'm now glad i went with the 45". Picture uses crisp, colors vibrant, and dark blacks. Easy setup as well.
