Sharp Roku TV OLED 4K vs LG C5 77-inch OLED TV

The LG C5 is the better TV. Its OLED evo panel with Brightness Booster is brighter in a lit room, and the a9 Gen8 processor handles upscaling and motion better than Sharp's set. The Sharp is a smaller 65-inch OLED with Roku built in, which suits people who want the Roku interface and a simpler remote. Reviewers rate the LG C5 highly for color accuracy and movie performance; the Sharp's Roku integration is its main draw.

  • Choose the Sharp Roku TV if you want Roku built in, a 65-inch OLED, and a home screen that puts streaming, inputs and free live channels in one place.
  • Choose the LG C5 if you want the larger 77-inch picture, higher brightness in a bright room, and LG's stronger processing and color accuracy.

What people mention
  • Picture qualityPraisedOwners call it one of the most color-accurate displays they have used, with sharp detail at 77 inches.
  • BrightnessMixedBrightness Booster helps in lit rooms, but reviewers say it still trails the brightest QD-OLED and Mini-LED rivals.

Questions and answers

Which is better for a bright living room?
The LG C5. Its OLED evo panel with Brightness Booster holds up better in a lit room. The Sharp uses Dolby Vision IQ to adapt to ambient light, but it is not as bright.
Is the LG worth stepping up to over the Sharp?
Yes, if you want a bigger picture and stronger processing. The LG adds 12 inches of screen, the a9 Gen8 processor and better brightness. The Sharp's edge is Roku built in.
Which has the better smart TV system?
They suit different habits. Roku on the Sharp is simple and puts free live channels in one guide. LG's webOS with the Magic Remote offers deeper settings and pointer control.

Yes. The Sharp supports Dolby Vision IQ and Dolby Atmos through its 30W speakers. The LG supports Dolby Vision, HDR10 and HLG, plus Dolby Atmos with a9 AI Sound Pro.
Which is easier to wall-mount?
The Sharp. At 51 lb and 65 inches, it is lighter and smaller than the 77-inch LG, so it fits more walls and mounts.
