Match the frame rate
UK and European channels are broadcast at 25 or 50 frames per second. Shown on a TV running at 60 Hz, motion can judder. Nvidia’s Match frame rate (beta) switches the display to suit the content:
- Start playing a channel.
- Press the Settings button on the remote and choose Match frame rate (beta) from the quick settings.
Nvidia notes three things: it’s an experimental feature that not all apps support, some TVs struggle with some refresh rates, and the display goes back to its original refresh rate when playback stops, so you activate it each time. To make it one press, set the remote’s Settings button to do it: SettingsRemotes & AccessoriesCustomize Settings button, then choose Match frame rate (beta).
Nvidia also says Plex and Kodi already match the refresh rate automatically. Some IPTV players have their own frame-rate option; check your player’s settings. Background: frame rates explained.
Resolution and display modes
Choose your TV’s resolution under SettingsDevice PreferencesDisplay & SoundResolution. For modes that aren’t in the main list, Nvidia points to Advanced display settingsCustom display mode in the same menu. If most of what you watch is UK television, a 50 Hz mode your TV supports avoids switching back and forth.
Dolby Vision has its own switch in Display & Sound for compatible TVs; most IPTV channels are SDR. If the picture is cut off at the edges, use Adjust for overscan under the advanced display settings.
AI upscaling: what it does and doesn’t do
The Shield’s upscaling is under SettingsAI upscaling, with three modes: Basic, Enhanced (the default) and AI-Enhanced, which adds an adjustable detail enhancement. A side-by-side demo mode lets you compare them.
Nvidia lists when AI upscaling doesn’t apply, and falls back to Enhanced:
- the video is below 480p;
- the video frame rate is higher than 30 Hz;
- the video is in RGB colour space.
That second point matters for live TV: many channels, especially sport, run at 50 frames per second, so AI-Enhanced won’t apply to them. It can still help 25 fps programmes and films. User reports also say upscaling switches off when frame-rate switching changes the output, so try both and keep what looks best.
Sound
- Sound cuts out or a format won’t play through your soundbar or receiver: set the formats manually under Advanced sound settingsAvailable formats. See audio passthrough.
- Lip sync out: use the Audio video sync slider under the advanced Display & Sound settings.
- TV or receiver control: Power control in Display & Sound sets HDMI-CEC or IR control.
Storage for apps and guides
Nvidia’s path to use a USB drive as extra app storage is SettingsDevice PreferencesStorage, choose the drive, then Set up as device storage. It formats the drive. See Android TV storage full.
