Samsung S90D 65-inch (QN65S90D)

4.6

$1,597

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

Strengths

— Third-generation QD-OLED panel delivers wider color volume than competing WOLEDs, especially on saturated reds and greens
— Roughly 1,300 nits peak HDR brightness on a 10% window — the brightest QD-OLED Samsung has shipped
— All four HDMI ports are HDMI 2.1, with native 120Hz and a firmware-enabled 144Hz mode on HDMI 4 for PC use

Watch-outs

— Samsung still refuses to support Dolby Vision — disc players and streaming services fall back to HDR10+
— Standard matte coating (not the nano-textured S95D coating) shows brighter room reflections
— Tizen home screen is ad-heavy and difficult to fully suppress

Ranked #5 in Best 4K TVs

TCL 43Q651G Q-Class QLED 43-inch

4.1

$299

TCL's 2024 Q-Class is the genuine 43-inch sweet spot — a real QLED panel with quantum-dot color, Dolby Vision support, and Google TV at $300. It is not a gaming TV and the lack of local dimming caps HDR potential, but for a bedroom, office, kitchen, or small living room it is the best budget 4K TV you can buy without compromising the HDR ecosystem.

Strengths

— Real QLED panel with quantum-dot color enhancement at the sub-$300 price tier — uncommon at 43 inches
— HDR PRO+ with Dolby Vision, HDR10+, HDR10, and HLG all supported in a budget TV
— TCL AIPQ processor with deep-learning upscaling makes 1080p Netflix and cable look respectable on the 4K panel

Watch-outs

— Direct-LED backlight without local dimming — HDR has limited dynamic range and dark scenes show backlight uniformity issues
— 60Hz refresh rate only; no ALLM or VRR, gaming-focused buyers should consider a different model
— Only 3 HDMI ports total, one with eARC; none are HDMI 2.1

How they stack up

Samsung S90D 65-inch (QN65S90D)

Costs roughly $700 less than the LG OLED G4 at street, with comparable peak HDR brightness on smaller windows but without Dolby Vision support. Versus the TCL 65QM7K it is a different category — true OLED black levels at a price closer to flagship mini-LED than to flagship OLED. Against the Hisense 65U7N the Samsung is double the price but the per-pixel contrast and color volume justify the gap for serious movie watching.

TCL 43Q651G Q-Class QLED 43-inch

Sits in a different category from the other picks — direct-LED, 60Hz, no local dimming. The closest sibling in this guide is the TCL 65QM7K, which adds mini-LED, 144Hz, and Halo Control for triple the price; the gap is enormous. Compared to the Hisense 65U7N this TCL trades all the premium features for a quarter of the price and a 22-inch smaller screen suited to genuinely small rooms.
