The Sony InZone M10S is the first OLED monitor Sony has released, and it just so happens to be the brightest, too. However, a lagging warranty holds it back.
It's got the best IPS panel, is supremely well-calibrated, and easily stands out above the rest of the pack. You'll want a top-end GPU like the RTX 4080 Super to get the most from a 4K monitor.
