"How can I stream HEVC videos on my 4K TV that supports HEVC but doesn't seem to play them?"
HEVC (High-Efficiency Video Coding), also known as H.265, is a more advanced video compression standard compared to the older H.264 codec.
It allows for higher-quality video at significantly lower file sizes.
4K TVs that support HEVC should be able to play HEVC-encoded videos natively, without the need for transcoding.
However, some older 4K TVs may not have the necessary hardware decoders to handle HEVC playback.
The issue of HEVC videos not playing on a 4K TV that supports the codec could be due to the video bitrate or resolution exceeding the TV's supported specifications.
HEVC has different levels and profiles that define the maximum resolution, frame rate, and bitrate.
Newer 4K TVs from 2015 and later typically support HEVC Main and Main 10 profiles up to Level 5.1, which can handle 4K video up to 60fps.
Older 4K TVs may only support up to Level 4.1, limiting the maximum resolution and bitrate.
To ensure HEVC playback, check your TV's technical specifications to see the supported HEVC profiles and levels.
This information is usually found in the TV's manual or on the manufacturer's website.
If the HEVC video's bitrate or resolution exceeds your TV's capabilities, the video may not play or may display artifacts.
Trying a lower-bitrate HEVC video or transcoding the video to a more compatible codec like H.264 may resolve the issue.
Some media players, such as Plex or Emby, can automatically transcode HEVC videos to a compatible format for your TV, effectively bypassing the HEVC playback limitation.
Using a separate media streaming device, like a Roku, Amazon Fire TV, or Apple TV, can also help, as these devices often have more advanced HEVC decoding capabilities compared to older smart TVs.
HDMI cables can also play a role in HEVC playback.
Make sure you're using a high-speed HDMI cable that can handle the bandwidth required for 4K HEVC video.
Some video players, like VLC or Kodi, have built-in HEVC decoders that may work better than the TV's native video player.
Trying different media players can help identify the issue.
Firmware updates for your 4K TV can sometimes add or improve HEVC playback support.
Check for any available updates from the manufacturer and install them.
If all else fails, you may need to consider upgrading your 4K TV to a newer model that has more robust HEVC decoding capabilities to ensure smooth playback of high-quality 4K HEVC content.
