LG C5 OLED 55"
no budget ceiling
The consensus best 55-inch TV of 2026 — four independent testing outlets rank it first: OLED contrast, Dolby Vision, and four full-bandwidth HDMI 2.1 ports at a mid-range price.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It's a dark-room TV. WOLED gives you the best picture in the segment with the lights down, but in a sun-filled room the $800 Hisense U8QG's 5,000-nit mini-LED simply looks brighter and better — for $330 less. Judge your room before your budget.
Dealbreaker? Runner-up №1 (Hisense U8QG) owns the bright room for $330 less ↓

Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the LG C5 OLED 55" is right for you
It avoids every trap below — and for anyone, no cap, it is the pick because it delivers:
Samsung skips Dolby Vision
Every Samsung set in this size — the S95F, S90F and QN90F — does HDR10+ only, with no Dolby Vision at all. Apple TV+, Netflix and Disney+ lean on Dolby Vision, so their best HDR streams drop back to plain HDR10 on a Samsung panel.
Two HDMI 2.1 ports, not four
The Hisense U8QG, both TCL mini-LEDs and even the $2,398 Sony BRAVIA 8 II ship with only 2 HDMI 2.1 ports; the LG and Samsung sets have 4. A console, a PC and a soundbar run out of full-bandwidth ports fast — and on budget models not every port carries full bandwidth.
There is no cheap OLED at 55 inches
55-inch OLED starts at ~$848 (LG B5) — no sub-$600 OLED exists at this size. Everything cheaper is mini-LED, and mini-LED blooms: halos around bright objects on dark backgrounds. The TCL QM6K runs ~240 dimming zones against the QM7K's ~640, and that gap is exactly what blooming control costs.
