LG OLED 65B5 65" 4K Smart TV vs LG A2 OLED 4K Smart TV

Both are 65-inch LG OLEDs with perfect blacks and wide viewing angles, so the picture quality gap is smaller than the spec sheet suggests. The B5 is the better buy for most people: it adds a 120Hz panel, four HDMI 2.1 ports with VRR and ALLM, a newer α8 processor, and Wi-Fi 6, which matter for gaming and for a TV you keep for years. The A2 is a solid choice only if you watch movies and shows and never game, since its 60Hz panel and HDMI 2.0 limit it to 60fps and cap console features.

  • Choose the LG B5 if you game on a PS5, Xbox Series X or PC, or want a TV that stays current for the next several years.
  • Choose the LG A2 if you mainly stream movies and shows and want the OLED look without paying for gaming features you will not use.

What reviewers say

LG OLED 65B5 65" 4K Smart TV

Owners of the B-series generally praise the picture, calling the blacks and contrast a clear step up from LED. Common complaints are modest brightness in daylight rooms and weak built-in speakers.

What people mention
  • Picture qualityPraisedOwners say the OLED panel gives deep blacks and rich contrast that LCD sets can't match.
  • BrightnessCriticisedReviewers note the B5 is dimmer than the C5, so highlights and daytime viewing suffer.
  • SoundCriticisedThe 20W 2.0 speakers are called thin, with most owners recommending a soundbar.
  • GamingPraisedFour HDMI 2.1 ports, VRR and low lag make it a popular pick for consoles.

Questions and answers

Which is better for gaming, the LG B5 or the LG A2?
The B5, clearly. Its 120Hz panel, VRR, ALLM and four HDMI 2.1 ports let a PS5 or Xbox Series X run at up to 4K 120Hz with smoother motion. The A2 tops out at 60Hz over HDMI 2.0.
Is the LG B5 worth stepping up to over the A2?
For most buyers, yes. The B5 adds 120Hz, HDMI 2.1, a newer processor and Wi-Fi 6, which keep it useful longer. If you only watch movies and shows, the A2 covers the basics.
Which has better sound?
The A2 lists Dolby Atmos support, while the B5 has a 20W 2.0 system without Atmos. Neither matches a dedicated soundbar, so plan on one either way.
Do both support Dolby Vision?
Yes. The B5 supports Dolby Vision, HDR10 and HLG. The A2 supports Dolby Vision IQ, which adjusts the picture to room lighting.
Which lasts longer?
Both use OLED panels with similar lifespans, and LG rates them similarly for burn-in risk. The B5 has newer internals and more current connectivity, so it stays capable longer as streaming and console features advance.
Which is better in a bright room?
Neither is a bright-room standout, since OLED panels trade peak brightness for contrast. The A2's Dolby Vision IQ helps adjust to light, but a bright room favors a bright LCD instead.
