If you prioritize a wider, more immersive display for gaming or multitasking, the LG with its ultra-wide screen could be a better choice, albeit at a higher price. On the other hand, the Acer offers a traditional aspect ratio which may be preferred for general use and productivity, along with being somewhat less expensive. Both monitors are OLED with similar high refresh rates, providing excellent contrast and color quality for HDR gaming and media. However, for tasks like digital photo editing, both monitors perform well. The larger size of the LG may affect text clarity and sharpness slightly due to its lower pixels per inch. Give Feedback
