About this product

Our take
The GM2711S offers a nice balance of resolution and speed. QHD at 27 inches looks sharp, and 180Hz with 0.5ms response time keeps gameplay fluid. The IPS panel provides good colors, but the 250 cd/m² brightness is a letdown—it's dim compared to many competitors. No adaptive sync listed, which could be a concern for some. At $379.90, it's priced higher than similar spec monitors with better brightness. Overall decent, but not outstanding.
