Fire TV — Enable 50 Hz & Match Frame Rate (Ireland)

Last updated: 18 September 2025 GMT

Irish live sport is produced at 50 Hz. Setting your Fire TV to use 50 Hz and Match Original Frame Rate reduces motion judder and frame drops.

Why 50 Hz matters (Ireland)

• Most Irish/UK broadcasts target 50 fps / 50 Hz.
• Outputting at 60 Hz forces a cadence conversion, which causes judder on fast action.

Step-by-step: enable 50 Hz & match frame rate

1. Open Settings → Display & Sounds → Display.
2. Set Video Resolution to Auto (preferred) or a fixed 1080p 50 Hz/2160p 50 Hz if available.
3. Go to Match Original Frame Rate (or Dynamic Range & Frame Rate) → set to On.
4. (Optional) Under Audio, use Stereo for older TVs if audio sync drifts.

Quick checks (takes 60 seconds)

• Play a live sports clip. Fast pans should look smooth without “stutter every second”.
• Press your TV’s Info (if available) to confirm 50 Hz output.
• If motion is still odd, disable the TV’s motion smoothing feature.

Network tips for stability

• Prefer Ethernet (via a USB-OTG adapter on Fire TV Stick models).
• On Wi-Fi, use 5 GHz non-DFS (36/40/44/48) @ 40 MHz if your router allows it.

Common issues

“Match frame rate” option missing

Update Fire OS and the streaming app; reboot the device. Some older apps switch rate only when full-screen starts.

Still seeing judder at 50 Hz

Confirm your TV input is set to enhanced/HDMI UHD color if using 4K. Turn off the TV’s motion smoothing, then retest.

Audio out of sync after switching rate

Toggle Stereo vs Dolby in Audio settings; some soundbars need a power cycle after refresh-rate changes.
