onn 55" 4K Roku Smart TV vs onn 32" Building Block Roku TV

These are two very different onn TVs, not two versions of the same one. The 55-inch 4K set is the pick for a living room or main TV: bigger panel, four times the pixels, three HDMI ports and a 400 x 200 VESA mount for wall hanging. The 32-inch Building Block set is a small 1080p kids' room TV with a white brick-style bezel and a tempered glass screen; it rates 4.5 out of 5 from 61 ratings, but it is a secondary-room product. Both run Roku with a 60 Hz panel, and both are budget builds, so expect basic speakers and average contrast either way.

• Choose the onn 55-inch 4K Roku TV if you want one large screen for a living room, movies and sports, and you need 4K, three HDMI inputs and a standard wall mount.
• Choose the onn 32-inch Building Block Roku TV if you are outfitting a kid's room or playroom and want a small, sturdy, playful set that is easy to move.
