Samsung S90D 65-inch (QN65S90D)

4.5

2 sources$1,149as of Aug 16

Samsung's mid-tier QD-OLED is the value play for buyers who want OLED picture quality without paying flagship money. On certain content the QD-OLED panel renders saturated colors more vividly than the LG G4 does, and street pricing under $1,500 makes it the cheapest entry to true premium picture quality.

Strengths

— All four HDMI ports are HDMI 2.1, with native 120Hz and a firmware-enabled 144Hz mode on HDMI 4 for PC use
— Tizen smart OS is fast and responsive, with deeper game-streaming integration than Google TV
— Frequently discounted below $1,500 — the cheapest premium OLED experience on the market

Watch-outs

— Samsung still refuses to support Dolby Vision — disc players and streaming services fall back to HDR10+

Ranked #5 in Best 4K TVs

TCL 43Q651G Q-Class QLED 43-inch

3.1

1 source$228as of Jun 8

The TCL 43Q651G is the 43-inch size of TCL's 2024 entry-level Q6 QLED, a 60Hz Google TV with Dolby Vision support and no local dimming. RTINGS, which bought and tested the 75-inch version and says its results are mostly valid for the 43-inch, rated the Q651G 5.8 out of 10 and called it sub-par for mixed usage: poor black levels in a dark room, unremarkable SDR brightness, inadequate HDR brightness and weak reflection handling. RTINGS judged it at its best in a moderately lit room, which is the case for it as a small bedroom or office set.

Strengths

— One of the few 4K QLED sets sold in a 43-inch size
— Supports Dolby Vision, per RTINGS
— Runs Google TV (version 12) with voice control and a large app selection

Watch-outs

— Awfully slow pixel transitions make motion blurry, per RTINGS

How they stack up

Samsung S90D 65-inch (QN65S90D)

The Samsung S90D 65-inch costs less than the LG OLED evo G4 65-inch and does without Dolby Vision, which the LG supports. Its QD-OLED panel renders saturated colors more vividly than the LG on certain content. Against the TCL 65QM7K it has four HDMI 2.1 ports to the TCL's two, while the TCL peaks around 2,600 nits against the Samsung's roughly 1,300.

TCL 43Q651G Q-Class QLED 43-inch

The 43Q651G is the only 43-inch set on this page and by far the cheapest, but it is also the weakest performer: RTINGS scores it 5.8 out of 10, against 7.8 for the TCL QM7K and 8.6 for both the LG G4 and the Samsung S90D. Unlike the mini-LED TCL QM7K, it has no local dimming.
