Game Changer - Literally
I was able to pick this up on a Black Friday deal, and I am so happy I did. The absolute UPGRADE this thing is over any other monitor I have used can't be understated. It is a whole new experience, like I am using something other than my PC... it made everything feel new again. The colors, the smoothness of 240hz, the ability to use it as a TV if I wanted, it is all so much for the money. Gaming on this ... I will never go back to a normal sized monitor again. This an amazing experience that makes me want to play more and more. The only fault I can find is that the stand is a bit wobbly. It COULD be my desk that is leading to the shake, since the screen is so large. But I think a slightly more sturdy stand would be all this needs, and even with that, I am nit-picking.

Much more than just a large monitor
Removed two 27" monitors and using this 45" in there place.. much better for many reason, go middle line between monitors, and you can use your screen anyway and organize as you want. You can also use it to stream your favorite providers - excellent screen quality as well. Note monitor is HEAVY!

A gamer must have !!!
I’ve been using this LG 240Hz monitor daily, and the performance has been outstanding. The refresh rate makes a noticeable difference right away motion is incredibly smooth with no screen tearing or stuttering, especially during fast-paced gaming and high-frame-rate content. The display quality is sharp and vibrant. Colors look accurate, blacks are deep, and brightness is more than enough for both daytime and low-light use. Text is crisp, which also makes this monitor great for productivity and creative work when I’m not gaming. Setup was straightforward, and the on-screen menu is easy to navigate. Adjusting settings like refresh rate, brightness, and input options is simple and intuitive. The build quality feels solid, and the stand provides good stability while allowing for easy positioning. Overall, this monitor delivers exactly what you’d expect from a high-refresh-rate LG display speed, clarity, and reliability. Whether you’re gaming competitively or just want a smooth, premium viewing experience, this monitor absolutely delivers.
