Our take on the Samsung S90D 42" 4K HDR Smart OLED TV
The Samsung S90D is a 4K OLED TV using QD-OLED panel technology, which combines self-lit pixels with a quantum dot layer for high brightness and wide color. The 42-inch size is the smallest in the S90D line, aimed at bedrooms, dens and desk setups where a large TV won't fit. Compared with the LG C4, it generally goes brighter and has more saturated color, while the C4 handles dark-room detail slightly better and adds Dolby Vision, which Samsung omits. Reviewers rate its picture and gaming features highly but note the smaller size uses a different panel type than the larger S90D models.
- Bright QD-OLED picture with strong color volume
- Four HDMI 2.1 ports at 4K 144Hz for gaming
- Very low input lag and good motion handling
- Slim design with a near-borderless screen
- Tizen smart platform with plenty of apps

Questions and answers
- Is the 42-inch S90D the same panel as the larger S90D sizes?
- No. The 42-inch model uses a different OLED panel than the 55-inch and larger S90D sets, so brightness and color volume are not identical across sizes.
- Does the S90D support Dolby Vision?
- No. Samsung supports HDR10, HDR10+ and HLG but not Dolby Vision, so Dolby Vision content plays in HDR10.
- Is it good for gaming?
- Yes. It has four HDMI 2.1 ports, supports 4K at up to 144Hz, and has very low input lag and gaming motion features.
- What is in the box?
- The TV, a stand, a remote, a power cable and documentation. A wall mount and HDMI cables are not included.
- Does it have a tuner for over-the-air TV?
- It has an ATSC 1.0 tuner but no ATSC 3.0 (NextGen TV) tuner.
- Should I buy the 42-inch or a larger S90D?
- Choose the 42-inch for small rooms or desk use. If you have space and want the full QD-OLED performance, the larger sizes are the better fit.
