webOS reliability is excellent, with no bugs encountered during extended testing.
Pros: display technology, response time
Cons: setup ease, account requirements
Most long-term and first-impression testing was smooth and bug-free. One extended test found occasional brief wireless-audio dropouts, so accessory stability is not flawless.
Pros: overall image accuracy, resolution
Cons: motion clarity, response time
The hardware is widely regarded as excellent, but launch firmware varied across units and introduced inconsistent HDR, Dolby Vision, and processing behavior. Later updates fixed many of those problems.
Pros: panel type, display technology
Cons: account requirements, DTS support
Long-term reliability is not established, and one retail sample showed a green edge glow. Early software and gaming bugs also suggest some launch-period quality risk.
Pros: resolution, contrast ratio
Cons: HDR10+ support, account requirements
Reliability is the most serious customer concern. Numerous owners report crashes, freezes, black screens, reboot loops, or failures within months, even though some units remain rock-solid.
Pros: local dimming performance, HDR format support
Cons: gradient handling, banding control
