Our take on the Samsung QN42S90HA 42 OLED 4K UHD Smart Vision AI TV 42-inch

The Samsung S90H is a 42-inch OLED 4K smart TV, the smallest size in Samsung's 2026 OLED lineup. It uses a QD-OLED panel with HDR10+, a 165Hz refresh rate and Samsung's Vision AI processing, which puts it ahead of most 42-inch rivals on motion and gaming features. It suits gamers and movie watchers in a small or mid-size room who want deep blacks and wide viewing angles. Compared with LG's C-series OLEDs it trades Dolby Vision for higher refresh and brighter highlights, and it costs more than any LCD at this size.

Questions and answers

Is the Samsung S90H good for gaming?
Yes. The 165Hz refresh rate and low input lag suit consoles and PCs, and it supports variable refresh rate. It is one of the fastest 42-inch OLEDs you can buy.
Does it support Dolby Vision?
No. It supports HDR10+ and standard HDR10. LG's OLEDs at this size do support Dolby Vision, so check which format your streaming apps use.
Is 42 inches too small for a living room?
It depends on seating distance. At around 5 to 7 feet it fills the view well; in a large room most buyers want 55 inches or more.
How does it compare with the LG C-series OLED?
The Samsung has a higher refresh rate and brighter highlights; the LG adds Dolby Vision and tends to handle very dark scenes slightly better. Both use OLED panels with similar contrast.
What is in the box?
The TV, a stand, a remote and a power cable. A wall mount and HDMI cables are not included.
Can it be wall mounted?
Yes. It uses a standard VESA mount, and the slim panel sits close to the wall. Check the mount's weight rating for a 42-inch OLED.
