Frequently Asked Questions
Why does European football look choppy on Nvidia Shield?
European broadcasts run at 50Hz; playing them on a 60Hz display mode causes repeated frame judder.
How do I enable auto frame rate on Shield TV?
Enable AFR inside TiviMate Settings > Playback > Auto frame rate.
Does AFR cause black screen flashes?
A brief 1-second HDMI sync occurs when switching between 50Hz and 60Hz channels; setting delay to 0ms minimizes this.
