Picture & Display
HDR
The Aero supports HDR10 and HDR10+. It does not support Dolby Vision.
HDR10+ provides dynamic metadata capabilities comparable to Dolby Vision, adjusting brightness and contrast on a scene-by-scene basis for the best possible picture.
Resolution
The Aero detects your TV’s maximum supported resolution and outputs at that resolution. It maintains this throughout playback – it doesn’t change resolution based on the content you’re watching.
Refresh Rate and Auto Frame Rate
Your Aero can output video at different refresh rates, including 50 Hz and 60 Hz. The best setting depends on your TV and what you watch.
For most customers, we recommend leaving the Resolution setting on Auto. This lets Aero choose the best resolution supported by your TV. On most 4K TVs, this will be 2160p at 60 Hz.
Quick Media Switching
Aero supports HDMI 2.1 Quick Media Switching (QMS). On TVs that support QMS, Aero can dynamically switch refresh rate to match the content, using the refresh rates supported by the TV.
If QMS is working correctly, you do not need to enable Auto Frame Rate.
Using Auto Frame Rate
Auto Frame Rate helps reduce motion judder by switching Aero’s video output between 50 Hz and 60 Hz depending on the content you are watching.
It is switched off by default. You can turn it on here:
Settings → Display Settings → Auto Frame Rate
When Auto Frame Rate is turned on, Aero chooses the most suitable output refresh rate:
- 25 fps and 50 fps content uses 50 Hz output.
- 24 fps and 30 fps content uses 60 Hz output.
For example, Freely and UK catch-up content will usually use 50 Hz, while many films and US streaming programmes will use 60 Hz.
Turn on Auto Frame Rate if you notice slight judder, especially during panning shots or scrolling credits.
When Aero changes refresh rate as playback starts, some TVs may briefly show a black screen. This is normal and happens because the TV is switching video mode.
Auto Frame Rate and Match Frame Rate
Auto Frame Rate is not the same as full Match Frame Rate.
Auto Frame Rate chooses between 50 Hz and 60 Hz. This helps Aero match the main refresh rates used by UK TV, US TV and most streaming apps, while keeping mode changes to a minimum as you move between menus, apps and programmes. Aero’s menus work at both 50 Hz and 60 Hz, so you should not notice many changes while browsing and playing content.
For 24 fps films, Aero outputs at 60 Hz using 3:2 pulldown. This is a common way to show film content at 60 Hz and avoids the more frequent switching you can get with full Match Frame Rate, especially when moving between menus and content, or when using apps such as YouTube.
Manual Refresh Rate Selection
If Auto Frame Rate is turned off, Aero stays at the refresh rate selected in the Resolution setting.
The default is usually 2160p 60 Hz on a 4K TV, which gives the best overall experience across Freely, Netflix, YouTube and other apps.
Manual refresh rate selection is mainly useful if:
- You have Auto Frame Rate turned off.
- You mostly watch one type of content, such as Freely live TV.
- You are troubleshooting picture or motion issues with your TV.
If you mostly watch Freely live TV and notice slight judder on panning shots, you can manually select a 50 Hz output mode instead. This better matches the native frame rate of UK broadcast content.
If you use a mix of Freely, Netflix, YouTube and other streaming apps, Auto Frame Rate is usually the better option because it changes between 50 Hz and 60 Hz depending on the content.
Auto Frame Rate
Auto Frame Rate helps reduce motion judder by switching Aero’s video output between 50 Hz and 60 Hz depending on the content you are watching.
It is switched off by default. To turn it on, go to: Settings → Display Settings → Auto Frame Rate
How It Works
Different types of content are produced at different frame rates. UK TV content is usually based on 25 or 50 frames per second, while many films and US programmes are based on 24 or 30 frames per second.
When Auto Frame Rate is turned on, Aero chooses the most suitable output refresh rate:
- 25 fps and 50 fps content uses 50 Hz output.
- 24 fps and 30 fps content uses 60 Hz output.
For example, Freely and UK catch-up content will usually use 50 Hz, while many films and US streaming programmes will use 60 Hz.
Using Auto Frame Rate
Turn on Auto Frame Rate if you notice slight judder, especially during panning shots or scrolling credits.
When Aero changes refresh rate as playback starts, some TVs may briefly show a black screen. This is normal and happens because the TV is switching video mode.
Auto Frame Rate, Match Frame Rate and QMS
Auto Frame Rate is not the same as full Match Frame Rate.
Auto Frame Rate chooses between 50 Hz and 60 Hz. This helps Aero match the main refresh rates used by UK TV, US TV and most streaming apps, while keeping mode changes to a minimum as you move between menus, apps and programmes. Aero’s menus work at both 50 Hz and 60 Hz, so you should not notice many changes while browsing and playing content.
For 24 fps films, Aero outputs at 60 Hz using 3:2 pulldown. This is a common way to show film content at 60 Hz and avoids the more frequent switching you can get with full Match Frame Rate, especially when moving between menus and content, or when using apps such as YouTube.
Aero also supports HDMI 2.1 Quick Media Switching (QMS). On TVs that support QMS, Aero can dynamically switch refresh rate to match the content without needing to enable Auto Frame Rate, using the refresh rates supported by the TV.
If your TV supports QMS and it is working correctly, you can leave Auto Frame Rate switched off.
