Identify the viewing screen
Record the monitor or TV, connection and application location. On a multi-display setup, the settings window can describe a screen other than the one playing the programme.
Use Windows 11 System, Display and Advanced display, then select the intended display through the offered control. Keep its current resolution and refresh rate in the notes.
Read the available-mode qualification
Microsoft's current support explains that available rates depend on the display and supported arrangement. It also describes an asterisk for rates that require a resolution change.
A rate appearing in a list is not a promise that it preserves every other property. Read the offered combination rather than treating refresh as an independent unlimited slider.
Use a repeatable motion reference
Choose a permitted passage with recognisable motion and keep the app, source and TV processing unchanged. Record the source frame rate where reliable information exists.
The display's refresh count does not create new original camera frames. A higher number can change presentation without changing the source's production cadence.
Compare one supported mode
If a change is appropriate, use a documented mode and the displayed confirmation process. Confirm only when the picture is stable and controls readable. Let an unsuitable test revert through the supported mechanism.
Check text, video and the resulting resolution afterward. Do not call a softer interface a codec failure if the selected rate also changed pixel dimensions.
Keep adaptive features in scope
Windows 11 Dynamic Refresh Rate is hardware-qualified and distinct from every content-matching feature in a video app. Record its state when relevant rather than assuming it always matches a programme.
No PC, monitor or performance benchmark was tested here. This guide follows current Windows controls and does not prescribe one universal rate, promise smoother every-source playback or certify an IPTV application.
Keep display and source units separate
A display reports refresh in hertz, while a source can be described by frames per second. The numbers can be related without identifying the same stage. Keep the field labels in the support record and note any app-level content matching. A smooth-looking cursor is not a measurement of programme cadence. If the intended video improves but another ordinary task becomes difficult, record that tradeoff before keeping the mode. The finished configuration should remain usable for the actual household rather than serving one isolated demonstration.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
- Microsoft display refresh settings — Official current support excerpt: selected display, available rates and asterisk indicating resolution change. No monitor benchmark performed.
- Microsoft HDR settings — Official current article section inspected: per-display selection, battery policy and duplicate/extend qualification; no PC or HDR signal tested.
