onn 55" 4K Roku Smart TV vs Onn 65-inch 4K Roku Smart TV

Both are budget onn Roku TVs with the same 60Hz LED panel, 4K resolution and three HDMI ports, so the real choice is screen size. The 65-inch adds HDR and voice assistant support (Google Assistant, Alexa, Siri) that the 55-inch listing does not mention. Pick the 55-inch if the room is small or seating is close; pick the 65-inch if you sit farther back and want the bigger picture. Owners of onn sets generally report decent picture for the money and basic build quality, with sound being the usual weak point on both.

• Choose the onn 55" if your seating distance is short, the wall or stand is tight, and you want the same Roku 4K experience in a smaller footprint.
• Choose the onn 65" if you sit several feet back, want HDR and voice assistant control, and can fit a larger set in the room.
