LG C5 OLED TV vs Samsung 77-Inch S84F OLED TV

The LG C5 is the better all-round TV and the one to buy for gamers and movie fans. It has four HDMI 2.1 ports, a 144Hz panel with G-Sync and FreeSync Premium, Dolby Vision and Dolby Atmos, and reviewers rate its picture highly. The Samsung S84F is a larger 77-inch OLED with a clean Tizen system and strong anti-reflection, but it runs at 120Hz, has only a 2-channel speaker setup, and lacks Dolby Vision. Choose the C5 for features and gaming; choose the S84F if a bigger screen matters more than extras.

  • Choose the LG C5 if you want the most complete OLED for gaming and movies, with four HDMI 2.1 ports, 144Hz VRR, Dolby Vision and Dolby Atmos.
  • Choose the Samsung S84F if you want a 77-inch OLED screen and prefer Samsung's Tizen interface over LG's webOS.

What reviewers say

LG C5 OLED TV

  • 4.8 / 518,000 ratings

With 4.8 out of 5 from about 18,000 ratings, owners are largely enthusiastic about the C5's picture and gaming features. They praise crisp, vivid images with deep blacks, even pixels and easy setup. The main complaints are value for money, banding in dark scenes and the fixed stand.

What people mention
  • Picture qualityPraisedOwners praise the crisp, vivid picture, rich color and perfect blacks, especially for dark-room movies.
  • BrightnessMixedMany say the high brightness makes the picture pop, but some find it less bright or colorful than competing OLEDs in well-lit rooms.
  • GamingPraisedGamers like the 144Hz VRR, low response time and four HDMI 2.1 ports.
  • ReflectionsMixedThe anti-glare coating helps, but owners still notice reflections in daylight.

Samsung 77-Inch S84F OLED TV

Owners rate the S84F as a strong value OLED with excellent contrast and a clean, glare-resistant screen. Most criticism centers on the weak built-in sound and the lack of Dolby Vision.

What people mention

  • Glare handlingPraisedThe anti-reflection coating is repeatedly called out as effective against windows and lamps.
  • SoundCriticisedReviewers say the 2-channel speakers are thin and recommend a soundbar.
  • BrightnessMixedFine for most rooms, but HDR highlights look dimmer than on Samsung's QD-OLED sets.

Questions and answers

Which is better for gaming, the LG C5 or the Samsung S84F?
The LG C5. It has a 144Hz VRR panel, G-Sync and FreeSync Premium, 0.1ms response and four HDMI 2.1 ports. The S84F tops out at 120Hz with fewer gaming features.
Is the Samsung S84F worth stepping up to for the bigger screen?
If screen size is your priority, yes. The 77-inch S84F gives you a noticeably larger picture. You give up Dolby Vision, 144Hz gaming and better built-in sound.
Which has better sound without a soundbar?
The LG C5. It supports Dolby Atmos and owners say it does not need a soundbar. The S84F uses a basic 2-channel speaker setup.
Does the Samsung S84F support Dolby Vision?
No. It handles OLED HDR but not Dolby Vision. The LG C5 supports Dolby Vision, HDR10 and HLG.
Which lasts longer?
Both are OLED TVs with similar panel life. The LG C5 promises up to 5 years of webOS updates, which helps it stay current longer.
Which is better in a bright room?
The S84F has strong anti-reflection coating, which helps with glare. The C5 uses Brightness Booster but reviewers say it is not as bright as some rival OLEDs.
