3.Use of test videos to verify real resolution

Marketing specs are good, but how do you make sure that the TV actually displays 4K instead of scaling Full HD? You can use test videos that show the difference between resolutions. Here's how to do it:

1. Download to a flash drive or play a YouTube test video with clear lines and text (example: YouTube's 4K Resolution Test).
2. Run the video on the TV and get close to the screen (at a distance). ~30cm).

If you have a PC or a Mac, you can determine the resolution of your TV by connecting it as an external monitor, and this method works 100% precisely because the operating system shows the actual resolution that the display supports.

1. Turn on the TV and press sequentially on the remote: Menu → Settings → All Settings → General → About → Press 5 times on Model
2. You'll open a developer menu. You can find a Display Info or Panel Information section.
3. Detailed information about the matrix will be provided here, including native resolution (Resolution field or Panel Res).

In some firmware (for example, on Mi TV 4S), the service menu opens through ADB.

1. Connect the TV to your PC via Wi-Fi (enable USB debugging in the developer settings).
2. Enter the command in the terminal: adb shell dumpsys display
3. In the conclusion, find the line mBaseDisplayInfo=DisplayInfo - there will be a physical resolution.

Alternative methods: box, documentation and annexes

If the TV isn't unpacked yet, or if you don't want to turn it on for inspection, you can get permission by documentation or packaging.

• 🛒 Check or warranty card: Sometimes there is a duplicate model and key parameters.
