Quick verdict
The G80SH adds what earlier Samsung 27-inch 4K OLEDs lacked: full-bandwidth DisplayPort 2.1 and USB-C with high-wattage charging. Press Start's hands-on review found it more vibrant than the previous model and noted the anti-reflective coating reduces glare in bright rooms while slightly dulling blacks.
We found no instrument-based measurements yet, so our assessment is specification-based. Samsung also removed the smart TV features of the previous generation, which some buyers valued.

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.
Motion, response, and latency
At 240Hz, QD-OLED's near-instant response gives clean motion. We have no attributable measurements for this model.
Image quality and HDR
PC Monitors lists 250 nits typical and about 1,000 nits HDR peak with DisplayHDR True Black 400. Press Start observed stronger vibrancy than the previous model and slightly dulled blacks from the anti-reflective finish. Specification-based and qualitative only.
Connectivity, PC, and console notes
DisplayPort 2.1 at UHBR20, two HDMI 2.1 ports, USB-C with DisplayPort Alt Mode and high-wattage charging (98W per PC Monitors; the listing states 96W), and two USB-A ports.
OLED care and warranty
The listing mentions OLED Safeguard+ and a 3-year warranty. Confirm burn-in coverage with Samsung.
Warranty: The Amazon listing title states a 3-year warranty and OLED Safeguard+. We did not verify burn-in wording for this specific model; Samsung's G81SF page covers burn-in at normal usage.

No. The G80SH adds DisplayPort 2.1 and USB-C with charging. The G81SF has DisplayPort 1.4 and no USB-C.
Final recommendation
Promising and well-equipped; we would like instrument measurements before ranking it higher.
