Which is better for movies: LG C4, Samsung S90D, or Sony Bravia 8?

For movies first, a fair short answer is:

1) Sony Bravia 8 — often the best pick if you care most about cinematic processing, motion handling, upscaling, and very accurate out-of-the-box tuning.
2) LG C4 — an excellent all-round choice for movies, with great contrast, strong HDR performance, and full Dolby Vision support.
3) Samsung S90D — very strong picture quality and often the brightest-looking option, but its movie appeal can be hurt by the fact that Dolby Vision support is not available on Samsung TVs.

Quick take

• Sony Bravia 8: A strong choice for film presentation, especially if you value smooth motion, clean upscaling, and a more reference-style image.
• LG C4: Close behind for movies, and usually the better value if you also want a great gaming TV.
• Samsung S90D: Excellent HDR impact and color, but less ideal for movie fans who want Dolby Vision.

Important caveat on the S90D

The S90D can vary by size and region: some versions use QD-OLED, while others use WOLED. That can noticeably change brightness and color volume, so it’s worth checking the exact model before buying.

Bottom line

• Best movie TV overall: Sony Bravia 8
• Best value/movie + gaming balance: LG C4
• Best if you want vivid HDR and don’t care about Dolby Vision: Samsung S90D
