Quick verdict
The G81SF is a 27-inch 4K QD-OLED for players who want sharp text and fast gaming in a room with some light. Samsung's Glare Free finish is less glossy than typical QD-OLED coatings, and the metal stand adjusts in every direction. TechRadar called it one of the best 27-inch 4K gaming monitors, praising image quality, performance, and heat management.
The feature set is lean for the price: no USB-C, no KVM, no speakers, and DisplayPort 1.4. TechRadar's review contains a port listing that conflicts with Samsung's specifications; we use Samsung's (two HDMI 2.1 ports).

What independent testing reports
We did not find numeric measurements for this exact model that we could attribute with their test conditions. Statements below are either manufacturer specifications or reviewers' qualitative findings, and each one says which.

Samsung lists FreeSync Premium Pro; the Amazon listing also states G-SYNC Compatible. Adaptive-Sync monitors generally work with NVIDIA cards over DisplayPort.
Final recommendation
Choose the G81SF for a lower-glare 27-inch 4K OLED. If you want more ports or Dolby Vision, the ASUS and Alienware versions are better equipped.
