Strong green or purple tint can indicate an unsupported HDR or Dolby Vision path, decoder issue or output-format mismatch. Check the source and supported device formats before changing every colour control. Ordinary calibration cannot reliably repair a wrongly interpreted signal. Start with a known supported SDR item, then compare the affected HDR rendition through the same route. A format-specific tint points toward signal interpretation, while a tint affecting menus and every input needs a wider display or connection investigation.
CompareSDR
A normal SDR source helps isolate HDR-specific handling. Keep the TV picture preset unchanged during the first comparison so that the source format is the main variable. Check whether the player's controls have normal colours over the tinted video and whether another input looks correct. A normal interface with an abnormal video region is useful evidence about decoding or colour conversion. Photograph the symptom only if needed, keeping account details out of the frame.
Inspect the format
Profile and output mode matter, not only a 4K label. Read the media information for HDR type and, where exposed, Dolby Vision profile rather than trusting a filename. Check both the player's decoder support and the display path. A device may handle SDR HEVC yet not support the HDR profile used by this rendition. If an authorized alternative is offered, compare that version instead of forcing a mode that the app documentation does not support.
Avoid permanent colour compensation
It can make correctly decoded content inaccurate. Return any experimental tint or white-balance changes to their recorded values before judging a compatible source. Compensating for a severely misinterpreted signal can make skin tones and neutral greys wrong on all other programmes. If the fault follows one format across applications, record the device firmware and output setting. If it follows only one file or stream, report that specific rendition and timestamp for source inspection.

An example to work through
Only one Dolby Vision source is tinted while normal SDR television looks correct. Switching to the supplied SDR edition restores neutral colours without touching the TV's tint control. That establishes a practical compatible path while leaving the affected Dolby Vision profile and application combination available for a precise support report.
Questions about this topic
Is this usually a DNS issue?
No. Address lookup cannot normally explain a decoded picture whose colour components are being interpreted incorrectly.
Should tint sliders be used to cancel it?
Resolve format interpretation first. Colour adjustments should follow correct format handling, otherwise they merely compensate for the wrong signal.
