onn 55" 4K Roku Smart TV vs TCL 55" 4K UHD Roku TV

Both are 55-inch 4K Roku TVs at the entry level, so the choice comes down to ports and picture processing. The TCL adds HDR10 and HLG support, four HDMI inputs with one eARC, and a 20-watt two-speaker system, which makes it the better pick for a soundbar, a console and a streaming stick all at once. The onn is the simpler set: three HDMI, one USB, no HDR, and a 400 x 200 mm mount pattern. Owners of both report the usual budget-LED trade-offs, uneven black levels and modest brightness, so buy on features rather than brand.

• Choose the onn 55" if you want a basic 4K Roku set for a bedroom or spare room and do not need HDR or a fourth HDMI input.
• Choose the TCL 55" if you want HDR10 support, four HDMI inputs with eARC for a soundbar, and stronger built-in speakers.
