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

The LG C5 is the better TV for most people. It has a brighter OLED evo panel, the a9 Gen8 processor, four HDR formats and LG's mature webOS, and owners consistently rate its color accuracy and movie performance. The Sharp is a 65-inch OLED with Roku built in, which suits Roku households and anyone who wants a simpler, streaming-first interface. The Sharp is smaller and its smart platform is more basic, but it costs less than the LG for the same OLED picture type.

  • Choose the Sharp Roku TV if you want a 65-inch OLED with Roku's interface, a customizable home screen and hands-free Google Assistant or Alexa control built around streaming.
  • Choose the LG 77-inch OLED if you want the larger screen, a brighter OLED evo panel, the a9 AI processor and full Dolby Vision, HDR10 and HLG support for movies and gaming.

What reviewers say

LG C5 77-inch OLED TV

Buyers describe the 77-inch C5 as one of the most color-accurate displays they have owned, with sharp detail that shines on movie nights. Longtime LG OLED owners say the line keeps improving year over year.

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.
  • SoundCriticisedThe 2-channel built-in speakers are described as thin, so many buyers add a soundbar.
  • GamingPraisedFour HDMI 2.1 ports at 120Hz with VRR make it a popular pick for console and PC gamers.

Questions and answers

Which is better for movie nights?
The LG. Its 77-inch OLED evo panel, a9 Gen8 processor and full Dolby Vision, HDR10 and HLG support give it the edge for films, and owners single out its color accuracy and detail.
Which has the better smart TV system?
It depends on taste. Roku on the Sharp is simpler and easy to customize. LG's webOS with the Magic Remote offers more apps and deeper picture controls.
Is the LG worth stepping up to over the Sharp?
Yes for most buyers. You get a much larger screen, a brighter OLED evo panel and a stronger processor. The Sharp makes more sense if you want Roku and a smaller footprint.
Which is better for gaming?
Both run at 120 Hz with four HDMI ports. The LG's a9 processor and brightness handling give it the advantage, though the Sharp covers the basics for console play.
Which has better sound built in?
The Sharp lists a 30W (15W+15W) speaker system with Dolby Atmos. The LG uses a 2-channel setup with Dolby Atmos and a9 AI Sound Pro. On paper the Sharp has more power; either benefits from a soundbar.
Do both support voice assistants?
Yes. Both work with Google Assistant and Amazon Alexa, and both include Bluetooth and Wi-Fi.
