KOORUI 24E3 165Hz Gaming Monitor vs ASUS ProArt Display PA278QV 27" WQHD Monitor
When you're deciding between the KOORUI 24E3 165Hz Gaming Monitor and the ASUS ProArt Display PA278QV 27" WQHD Monitor, the KOORUI takes the edge for gamers with its dazzling 165Hz refresh rate compared to ASUS's 75Hz.
