Our Verdict
Acer Nitro VG271UP Pbmiipx
ViewSonic VX2758-2KP-MHD
The Acer Nitro VG271UP Pbmiipx and the ViewSonic VX2758-2KP-MHD perform similarly overall, but there are a few notable differences between them. They're both 27" 1440p monitors with a 144Hz refresh rate and FreeSync support, but the Acer supports HDR, whereas the ViewSonic doesn't. The ViewSonic has a much better black uniformity and faster response time, but the Acer is more color accurate out of the box.
