Your LG OLED TV may be getting a big upgrade to its picture quality - for free

Key Takeaways
- A recent firmware update improves picture quality on LG C5 and G5 TVs.
- The update makes Dolby Vision content brighter and more vivid.
- All picture modes except Filmmaker Mode are affected.
What the Update Changes
Just days after offering a free audio upgrade, LG is providing a free visual upgrade, and users are noticing a big difference.
The firmware update modifies how Dolby Vision content appears on the C5 and G5 models:
- Images become significantly brighter.
- Overly dark shadows are reduced.
Dolby Vision being too dark has been a common complaint from LG owners, especially in bright rooms where sunlight or other strong lights hit the screen.
Before‑and‑After Comparison
Reddit users shared side‑by‑side images that illustrate the improvement:
Because the C5 already has a fairly impressive brightness compared to its peers, the upgrade is most noticeable on that set.
Additional Context
One Reddit user posted the latest version’s changelog, which notes:
“This update is a specific picture quality fix addressing user complaints regarding Dolby Vision brightness.”
The fix resolves an issue where Dolby Vision content (usually in Cinema Home mode) appears significantly darker than standard HDR10 content. The update also impacts the following picture modes:
- Cinema Home
- Vivid
- Game
- Standard
It does not affect Filmmaker Mode, preserving creator intent.
Why Filmmaker Mode Is Untouched
Dolby Vision aims to keep the creative vision of content producers, but it can clash with typical living‑room lighting conditions. By brightening most picture modes while leaving Filmmaker Mode unchanged, LG lets users choose between a brighter everyday experience and the creator‑intended look.
How to Verify and Install the Update
- Open Settings → All Settings → Support → Software Update.
- Check the software version. The update is version 33.30.92.
- If you’re not on this version, you can:
- Check for updates manually, or
- Enable auto‑updates to receive future fixes automatically.
