LG C5 vs LG G4: Which OLED Do Owners Pick?

The G4's headline hardware advantage is its second-generation Micro Lens Array, which LG rates at roughly 1,650 nits peak brightness in calibrated mode versus the C5's spec sheet, which tops out closer to 800-1,000 nits. Owner mentions back this up directly under the theme "brightness & glare": one G4 owner reports having to turn the brightness down rather than up, and another with an 83-inch G4 says they have "no need for something brighter" and calls the panel "a torch." We don't have equivalent brightness-specific mentions for the C5 yet — its two verified mentions are both about screen size — so this section can confirm the G4's brightness claim from owner testimony but can't yet confirm or contradict how the C5 performs in the same bright-room conditions.

Both TVs use OLED panels and carry the same burn-in risk profile per LG's own product data, including the 5-year burn-in warranty coverage on the G4. The G4's mention record includes two owner reports under "burn-in & panel longevity": one describes vertical banding appearing on a unit purchased directly from LG, and another discusses running the manual panel-refresh tool with limited effect, while noting that going looking for banding can make it more noticeable than it otherwise would be in normal content. Neither of the C5's two mentions touches on burn-in or panel longevity, so there is currently no owner-verified data point for the C5 on this specific risk — the shared warranty coverage and identical panel technology are the only basis for assuming parity.

Both TVs list four HDMI 2.1 ports, 144Hz, G-Sync compatibility, and FreeSync Premium — on paper, gaming performance should be a wash. The G4 has a verified gaming mention describing PS5 use and 4K Blu-ray playback as looking "unreal," with no loss of brightness or color volume in game mode. The C5's two mentions don't touch gaming at all — they're both about seating distance and screen size — so while the spec sheets are genuinely equal, we can only confirm gaming satisfaction from owner reports on the G4 side of this comparison.

Both TVs run LG's webOS platform, and per product data the G4 and C5 carry an identical 8.5 Smart TV Features subscore. In practice, the G4's mention record includes two separate owner reports of webOS issues after a recent update — one describing Plex playback stutter and memory warnings, another describing an unplug-and-replug troubleshooting cycle that didn't fix a recurring glitch. Both of those owners also flag the remote as a step back from earlier LG generations, with slower cursor calibration than the CX-era remote. None of this is C5-specific data — since both TVs share the same operating system and app suite, the pattern is worth knowing regardless of which model you buy — but only the G4 currently has owner reports confirming it happens in the wild.
