01 / THE IDEA

Fewer forum tabs.
More game time.

Streaming settings depend on the client, display, network and host software. We connect those dots, then give you a plan you can actually test.

Tell us your setup

Choose your streaming client, host, display goal, network and biggest issue.

Get a smart baseline

Receive a conservative starting resolution, frame rate, bitrate and HDR guidance.

Fix the actual bottleneck

Follow targeted checks for stutter, HDR, black screens, controls and display switching.

02 / INTERACTIVE BETA

Build your streaming blueprint.

Your answers stay in this browser. This tool provides an informed starting point, not a measured benchmark or an automatic configuration.

SETUP INPUTS~1 minute

Using the Steam Link app or Steam Remote Play instead of Moonlight? Couch Lag is built for Moonlight; many network tips still apply, but settings names differ.

Pick the biggest one. You can run Diagnose again for a second problem.

03 / GUIDED TROUBLESHOOTING

From first setup to problem solved.

Verify each individual setup task, tell us what happened, and get the next appropriate test, including isolating input lag across the PC, client, controller and TV. No blind driver changes. Beta challenge feedback, detailed task progress, test results, manually recorded stutter episodes, latency isolation answers and streaming statistics are stored on this device where browser storage is available.

Private by design: this beta does not transmit your answers anywhere. The exports stay on your device. Share reports exclude free-text notes by default; always review its preview before sharing. Links to official documentation require an internet connection. An exported diagnostic report may contain setup details; review it before sharing.

04 / TRANSPARENT BY DESIGN

No magic fixes.
Just better next steps.

What this beta does

Includes a local 10-minute user-testing challenge with optional feedback export. Offers rules-based starting settings, detailed setup micro-checklists, outcome-driven troubleshooting, user-entered Moonlight performance comparisons, a manual stutter episode logger, and guided single-variable experiments, plus an eight-question latency isolation wizard. Saves progress locally where supported; exports a detailed or share-ready report, plus an opt-in, 10-minute beta challenge for manual validation.

What it doesn't do

It cannot run experiments or benchmark a network automatically, detect stutters automatically, read Moonlight statistics, inspect hardware or host logs, change settings, or guarantee a fix. Performance figures must be entered by the user.
