Roku Pro Series 55-Inch 4K TV vs LG C2 42-Inch OLED TV

The LG C2 is the better picture for a dark room and the better gaming display: self-lit OLED pixels give true blacks, near-instant response and four HDMI 2.1 ports with G-Sync, FreeSync and VRR. The Roku Pro Series is the better fit for a bright living room and for people who want Roku's interface built in, since its Mini-LED backlight pushes far more brightness than the 42-inch C2, which LG itself notes is dimmer than its larger OLED evo models. The C2 is a 42-inch set, so it suits a desk, bedroom or small room; the Roku is a 55-inch set for a main room. Owners rate the C2 highly for picture and gaming, while Roku buyers value the simple OS and voice remote.

  • Choose the Roku Pro Series if you want a larger 55-inch screen for a bright room and prefer Roku's simple interface and voice remote over the deepest blacks.
  • Choose the LG C2 if you want perfect blacks, wide viewing angles and top-tier gaming features, and 42 inches fits your space.

Questions and answers

Which is better for a bright living room?
The Roku Pro Series. Its Mini-LED backlight gets much brighter, so it fights glare better. The 42-inch C2 is the dimmest C2 size.
Which is better for gaming?
The LG C2. It has under 1 ms response, VRR, G-Sync and FreeSync Premium, and four HDMI ports. The Roku lists 120Hz but no VRR or G-Sync.
Which has better picture quality in a dark room?
The C2. OLED pixels switch off for true black and no blooming. The Roku's local dimming is good but shows halos around bright objects on dark backgrounds.
Is the Roku worth stepping up to for the bigger screen?
If 55 inches matters more than perfect blacks, yes. It also adds Roku OS and Wi-Fi 6. If you watch in a dark room or game, the C2's picture is the step up.
Which lasts longer?
LED sets like the Roku carry no burn-in risk. OLED can retain static logos over years of the same channel, so vary content on the C2.
Which is better for a bedroom or desk?
The 42-inch C2. Its size and wide viewing angles suit close seating, and it doubles as a monitor with low input lag.
