Our Verdict

Dell UltraSharp U4021QW

LG 40WP95C-W

The LG 40WP95C-W is better than the Dell UltraSharp U4021QW. Both models target media creators, but the LG supports HDR, with amazing coverage of the DCI-P3 color space, and the Dell doesn't support HDR at all. The LG also has slightly better connectivity, with higher bandwidth Thunderbolt 4 ports.
