Is the 165Hz refresh rate worth it over a 120Hz OLED?

For gaming and fast sports, yes. A 165Hz panel can show smoother motion when the source and console or PC support it. For movies, the difference over 120Hz is small.

Does it support Dolby Vision?

No. It supports HDR10+ and standard HDR formats. Dolby Vision content plays in a fallback format, so buyers who want Dolby Vision should look at other OLED brands.

Is 77 inches too big for my room?

How does it compare with the S90F?

The S90H is the newer generation with a higher 165Hz refresh rate. Picture processing and brightness are expected to improve, but both are 4K OLEDs with HDR10+ and Dolby Atmos.

The TV, its stand, a remote, and the power cable. A wall mount and HDMI cables are not included.

Is it good for gaming?

Yes. The 165Hz panel, low input lag and Samsung's gaming features suit consoles and PCs. Check that your console or GPU can output high frame rates to use it fully.
