Check source resolution separately from TV output

Your television can report a 2160p HDMI signal while the player sends an upscaled 1080p stream. Look at the player’s available diagnostics for the video being decoded, then check the TV or receiver’s input information.

Keep four readings apart

Resolution is the number of pixels in the frame. Frame rate is the number of frames per second in the material. The display refresh rate describes how often the output updates. A player may also convert or preserve dynamic range. Those fields can move separately as you go from a menu to a movie or a live match.

Start with one programme and note its label and time. If the player reports a decoded format, record the resolution and frame rate it shows during playback. Look at the television’s input information next. If a receiver sits in the middle, check the input and output readings where it offers them.

Where the reading came fromWhat it can establish
Player information during playbackThe format the app reports for the current source or rendition.
TV HDMI informationThe signal that reached that HDMI input.
Device video settingsThe chosen output preference or allowed mode.
A package title such as 4KThe seller’s label for the offer. Confirm the specific programme.

Use the example to read your own screen

A player can report 1920 × 1080 at 50 frames per second. Your display can show a 3840 × 2160 signal at 50 Hz while the picture is being upscaled by the box. Those readings can both be accurate. If the player later changes to 1280 × 720, the TV can continue reporting 2160p even though the underlying image changed.

A more useful comparison is the same programme, the same picture controls and two known source renditions. Watch movement and fine detail, then check the player again. An output mode change alone can introduce a short HDMI transition, so give the screen time to return before judging the picture.

Keep the result with the plan decision

If a provider offers a named high-resolution sample, record the sample, device, time and reported source mode. If the player has no diagnostics, say which reading you can obtain. Use the public app or device documentation to confirm what the display chain can accept before treating an output indicator as evidence about a whole catalogue.
