LG OLED evo C4 42-inch TV vs Samsung S90H OLED 4K Smart TV

Both are 42-inch 4K OLEDs with four HDMI 2.1 ports, so the split comes down to picture handling and gaming. The LG C4 adds Dolby Vision and Dolby Atmos, which the Samsung S90H lacks, and it is the safer pick for movie watchers. The Samsung S90H counters with a 165Hz panel, Wi-Fi 6E and a brighter, punchier image, and it is the better fit for high-frame-rate PC gaming. Owners of both praise the deep blacks and wide viewing angles; the LG gets the nod on motion and format support, the Samsung on brightness and refresh rate.

  • Choose the LG C4 if you watch Dolby Vision movies and want the most complete format support and proven motion handling.
  • Choose the Samsung S90H if you game on a PC or console at high frame rates and want the higher refresh rate and brighter panel.

Questions and answers

Which is better for movies?
The LG C4. It supports Dolby Vision and Dolby Atmos, so it plays more streaming and disc content in its native format. The Samsung tops out at HDR10+.
Which is better for gaming?
The Samsung S90H for high-frame-rate PC play, thanks to its 165Hz panel. The LG C4 is the stronger console pick because of G-Sync certification and Dolby Vision gaming.
Is the Samsung brighter than the LG?
Yes. The S90H pushes more peak brightness in HDR, which helps in a bright room. The LG wins on black-level accuracy and motion.
Which lasts longer?
Both use OLED panels with similar lifespans. The Samsung promises up to seven years of OS updates versus five for the LG, so its software stays current longer.
Is the step up to the Samsung worth it?
Only if 165Hz gaming or extra brightness matters to you. If you watch Dolby Vision films, the LG C4 is the more complete set.
