Steam Link stutters and lags on my Android TV — how do I fix it?

The picture on the TV looks fine for a minute and then hitches: a frame held too long, a burst of judder in a pan, input that feels a step behind. You lower the resolution, it helps a little, then it comes back.

Steam Link is convenient if you live in Steam, but its settings on the TV are few, the game gets a generic pad, and when it stutters it does not tell you whether the problem is your Wi-Fi, the PC’s encoder or the TV box. So you guess.

And every guess costs a reconnect: leave the game, change a slider, start again.

A stream has a cadence — 60 frames a second, say — and the TV has a refresh rate. If the two do not line up, some frames are shown twice and some skipped, which looks like judder even when nothing was lost. Then the network: Wi-Fi in a flat with neighbours loses packets in bursts, and a lost packet means a frame arrives late or broken.

Finally the encoder: the PC may simply not keep up with the resolution and bitrate you asked for, and a client that only sees packet loss cannot tell that apart from a bad link. A stutter at the source looks like a stutter on the network unless the host tells you.

1. 01

   Wire the TV box if you can

   An Ethernet-connected TV box works the same in ChimpDeck and removes the biggest variable. If it must be Wi-Fi, the app enables Android’s low-latency Wi-Fi mode while a session is live.

2. 02

   Install ChimpDeck on the box and the host on the PC

   Android 8.0 or later with a hardware H.264/HEVC decoder; Windows 10/11 with an NVIDIA graphics card. Pair without a PIN. The whole app is driven by the remote — the full TV setup takes minutes.

3. 03

   Let the display follow the stream

   ChimpDeck switches the TV to the refresh rate that best multiplies the stream’s frame rate (120 Hz for 60 fps, for instance) and the frame pacer keeps presentation regular. Three pacing modes: lowest delay, balanced, smoothest.

4. 04

   Read the stats, not your gut

   The overlay shows frames, drops, repairs, encode time, round trip, decode time and pacing, plus the PC’s own report — and the PC panel says the cause in words: «the phone asks to repair: check the network» or «the PC isn’t keeping up with those frames».

5. 05

   Change quality without reconnecting

   Bitrate, frame budget and repair change live, mid-game. The regulator lowers bitrate and raises repair when it sees losses, and puts them back when the link recovers. Good starting settings are here.

6. 06

   Never play through a corrupted frame

   Every frame carries a checksum; a damaged one is repaired with FEC or skipped and a key frame requested, so blocks never smear across the TV.

• Display refresh matched to the stream

  The TV switches to a multiple of the frame rate; judder from mismatched cadences disappears.

• A regulator with the PC in the loop

  Capture cadence, encode time and real encoder output tell a source stutter from a network one.

• Hot changes, no reconnect

  Bitrate, budget and repair adjust live from the sofa, on the remote.

• Up to 120 fps where the box can

  The frame-rate row only offers rates the decoder really plays — [[stream-120-fps|here is how to get there]].
