Hey! We’ll fix your LG TV wrong colors in HDR fast — this is usually not “a bad panel,” it’s a mismatch in the HDR signal chain (TV ↔ HDMI ↔ console/streamer/PC). The top causes are: HDMI Ultra HD Deep Color disabled, RGB range / Black Level mismatch (Limited vs Full), or wrong Color Gamut / color space in the picture mode.

Quick questions so we pick the right fix (no random resets):
• What LG model and year? (OLED C1/C2/C3/C4, B-series, NanoCell, UHD, etc.)
• What source device shows the HDR color problem: PS5, Xbox Series X, PC, Apple TV 4K, Roku, built-in apps (Netflix/YouTube)?
• Is it all HDR or only one format: HDR10 vs Dolby Vision vs HLG?
• Describe the “wrong colors”: washed-out HDR, neon/over-saturated, green tint, purple/magenta skin tones, reds look orange, blacks look gray, banding?
• Connection: direct to TV or through a soundbar/AVR (HDMI passthrough / eARC)? Which HDMI port?

Reply with that and I’ll give you the shortest “top working fixes” checklist.

Perfect — SDR normal + HDR “weird colors” strongly points to an HDR signal format mismatch, not a panel defect.

Why this happens (common chain reaction):
• If the TV input doesn’t have HDMI Ultra HD Deep Color enabled, the TV may accept HDR in a reduced/incorrect format and you get wrong HDR color space, posterization, or odd tints.
• If the PS5/Apple TV outputs RGB Full while the LG input expects Limited (or vice versa), you can get washed-out blacks, crushed blacks, and colors that look “off.” On LG, that’s the Black Level (Low/High) setting.
• If your soundbar/AVR passthrough is forcing a different chroma format (like changing YCbCr / chroma 4:2:2 behavior), HDR can look oversaturated or strangely tinted depending on the TV mode.

We’ll do this in the fastest order: test direct HDMI (rule out passthrough), enable Deep Color, then lock in RGB range + Black Level, and finally tune the LG HDR picture mode (Color Gamut / Dynamic Tone Mapping / enhancements).

Totally fair — here are the safe checks that fix most LG HDR wrong colors cases without breaking SDR.

Step 1 — Enable HDMI Ultra HD Deep Color on the correct input
On LG webOS: Settings > General > Devices > HDMI Settings → turn HDMI Ultra HD Deep Color ON for the HDMI port your PS5/Apple TV uses.

Step 2 — Use a clean HDR picture mode baseline
When HDR is playing (so the TV is in HDR mode), set Picture Mode to a sane baseline like Cinema, Filmmaker Mode, or for gaming Game Optimizer (not Vivid). Then do:
• Turn OFF “extra” processing for testing: Dynamic Contrast, Super Resolution, Color Enhancement / Live Color, heavy AI Picture options.
• Set Color Gamut to Auto (avoid forcing Native/Wide unless you know why). Forced wide gamut can create that neon HDR look.

Step 3 — Fix the RGB range (the #1 washed-out/odd HDR cause)
On LG: find Black Level in Picture settings. General rule:
• If the device outputs Limited range, set LG Black Level to Low.
• If the device outputs Full range, set LG Black Level to High.

Next, we’ll confirm what the PS5 and Apple TV are actually outputting and eliminate the soundbar passthrough variable.

Nice — Deep Color being OFF would absolutely produce HDR color issues. Now we’ll clean up the remaining “strong reds / odd skin tones” by locking the signal format and removing double-processing.

Step 4 — Quick passthrough test (rules out soundbar/AVR altering HDR color)
For 5 minutes: connect the PS5 directly to the TV (same HDMI cable if possible). Then play an HDR game/menu you know looks wrong.
• If colors instantly look normal: the soundbar passthrough is the culprit (EDID / chroma format / HDMI bandwidth).
• If it still looks wrong: it’s device output settings + LG picture mode settings (we can fix that too).

Step 5 — Lock PS5 output to avoid weird color conversions
On PS5: Settings > Screen and Video > Video Output
• Keep 4K Transfer Rate on Automatic (or try -1 if you see flicker).
• Set RGB Range to Automatic first. If HDR looks washed-out or black level looks wrong, manually try Limited (most TVs expect Limited for video).
• If you switch PS5 RGB Range to Limited, keep LG Black Level = Low.

Step 6 — Fix “neon HDR” on LG (common)
In the HDR picture mode you’re using:
• Color Gamut: Auto
• Dynamic Contrast: Off (for testing)
• Peak Brightness: High (normal for HDR on many LG models)
• In Game Optimizer, avoid boosting “color” sliders aggressively — that can push reds into orange/neon territory.

Tell me what happens with the direct-to-TV test — that decides the fastest finish.

Yep — and this is a common “HDR wrong colors” scenario with soundbar/AVR HDMI passthrough.

Step 7 — Best practice wiring (keeps HDR colors correct)
Option A (recommended): Plug PS5/Apple TV directly into the LG TV, then send audio back to the soundbar via eARC/ARC.
This avoids the soundbar altering the HDR video signal, while still giving you full audio.

Step 8 — If you must use passthrough (soundbar HDMI IN → HDMI OUT to TV)
Check soundbar settings for anything like:
• Enhanced format, 4K Enhanced, HDMI 2.1, Dolby Vision passthrough, HDR passthrough
Enable the “enhanced”/bandwidth option if available. Some bars default to a limited mode that causes wrong chroma/color handling.

Also confirm the TV port the soundbar uses has HDMI Ultra HD Deep Color ON (you already did — great).

Step 9 — Cable sanity check
If the cable between device→soundbar or soundbar→TV is older, swap to a certified high-speed/ultra-high-speed HDMI cable. Bad bandwidth can force fallback modes that look like HDR color distortion or posterization.

If you tell me the soundbar model, I can point you to the exact “enhanced HDMI” setting name for it.

Yes — Apple TV 4K is famous for “everything in HDR/Dolby Vision” if the video format is set that way, which can make colors look inconsistent across apps.

Step 10 — Apple TV 4K settings that stabilize HDR colors
On Apple TV: Settings > Video and Audio
• Set Format to a normal SDR baseline (many people use 4K SDR), then turn ON:
• Match Content → Match Dynamic Range ON and Match Frame Rate ON.

This prevents forced HDR conversion and lets true HDR10/Dolby Vision play only when content is actually HDR. That’s a huge fix for “wrong colors in HDR” and “oversaturated HDR” complaints.

Step 11 — LG side (for the Apple TV HDMI input)
Keep: HDMI Ultra HD Deep Color ON, Color Gamut Auto, and use a consistent HDR picture mode (Cinema/Filmmaker) with processing minimized.

Great — you basically fixed the full HDR chain. Here’s the “keep it stable” checklist for LG TV HDR wrong colors:

Best practices (prevents washout, neon, and tint issues)
• Keep sources (PS5/Apple TV/PC) connected directly to the TV when possible; use eARC for audio. Passthrough is where color/EDID problems happen most.
• If HDR suddenly looks wrong, re-check only these 3 things first:
1) HDMI Ultra HD Deep Color still ON for that HDMI port
2) Device output: RGB Range Auto/Limited (and LG Black Level Low/High matches it)
3) LG HDR picture mode hasn’t switched to Vivid or had Color Gamut Native forced

• After firmware updates (LG webOS, console, Apple TV), a quick power cycle of the TV and device can clear handshake issues that cause weird HDR color space behavior.

If you want, tell me your exact LG model (C1/C2/C3 etc.) and I’ll give you a “known-good” HDR preset for gaming and movies.

Factory reset is last resort. Use this ladder (fast + low risk):

Reset ladder for LG HDR wrong colors
1) Power reset: unplug TV + source for 60 seconds, then reconnect (clears HDMI handshake bugs).
2) Confirm HDMI Ultra HD Deep Color is ON for that input (it sometimes gets toggled after port changes).
3) Confirm RGB range + LG Black Level match (Limited↔Low, Full↔High).
4) Switch to a clean HDR picture mode (Cinema/Filmmaker/Game Optimizer) and turn off extra enhancements; set Color Gamut Auto.
5) If problems happen only through a soundbar/AVR, bypass passthrough and use eARC again.
6) Only then: swap HDMI cable(s) (especially if you changed to 4K120/VRR).
7) Factory reset only if the TV is glitching across every input/app and settings won’t “stick.”

If you describe the exact “wrong color” symptom when it returns (washed out vs neon vs green tint), I can tell you which step to jump to.

Summary: If your LG TV shows wrong colors in HDR, fix the signal chain first: enable HDMI Ultra HD Deep Color on the right port, avoid soundbar/AVR passthrough when it alters HDR, and match RGB range with LG Black Level. Then keep HDR picture settings sane (Color Gamut Auto, avoid forced “Native/Wide” and heavy enhancements). Need the best settings for your exact LG model + PS5/Apple TV setup?
