If you prioritize competitive gaming and are willing to invest in premium performance, the Acer X27U with its superior responsiveness and very good refresh rate offers an edge. However, it falls short for productivity due to lower image clarity. The LG 34GP83A, with its wider screen and fair productivity score, is better for multitasking and offers a decent gaming experience at a lower cost, but isn't ideal for HDR gaming or media consumption. Choose the Acer for high-end gaming with better contrast and HDR; opt for the LG if you want a balance between work and play without the premium price tag. Give Feedback
