It’s not Nvidia G-Sync-certified, but we also got it to run G-Sync successfully (see our instructions for How to Run G-Sync on a FreeSync Monitor).Ĭonsole gamers will appreciate the monitor’s two HDMI 2.1 inputs that support variable refresh rate (VRR). In addition to a 120 Hz refresh rate, the FO48U supports AMD FreeSync Premium from 48-120 Hz. Gamers won’t be disappointed in the FO48U’s feature set though. Many 4K Blu-rays and even more streamed content is mastered in Dolby Vision. This isn’t a major factor for gaming, but if you plan to watch TV on the FO48U, it will be missed. The FO48U supports HDR10 and Hybrid Log Gamma (HLG) input but does not accept Dolby Vision.

When we ran our benchmark tests on the FO48U, its black levels were unmeasurable in every case, even when there was other content on screen. The word infinitely is not an exaggeration. This is thanks to its ability to shut off individual pixels on the fly to create an infinitely low black level. 42.1 x 26.6 x 9.9 inches (1069 x 675 x 251mm)Īs a self-emissive technology, OLED, like CRT and plasma, has tremendous dynamic range.
