Many Sony PlayStation 4 Pro game console owners face a situation where, after connecting to a modern Xiaomi Mi TV or Redmi TV, the picture remains in standard resolution. This is a common problem that is often solved by properly configuring ports and system parameters. It is important to understand that the console itself does not “enable” 4K forcing, but only offers available modes if the display is ready to accept them.
Xiaomi TVs running on Android TV or PatchWall have specific HDMI signal requirements to activate extended formats. Without the right configuration, you may not see the difference between Full HD and Ultra HD, even if your hardware technically supports high resolution. In this article, we will analyze each step required to activate a 4K HDR signal.
Checking the compatibility of equipment and cables
The first step is always to physically check the connections. HD 60Hz and support HDR cable HDMI High Speed or Premium High Speed cables, old cables left over from the high speed standard DVD-Players or consoles of the past generation, can physically not miss the desired amount of data.
Make sure your Xiaomi TV has ports that support HDCP 2.2. This is usually a specific port, often labeled HDMI 2.0 or HDMI (4K). Connecting to a regular port can limit the resolution to 1080p. It’s also worth checking that the TV menu for the selected input has HDMI 2.0 or Enhanced mode, if such an option is available in the model.
⚠️ Note: Use of cheap adapters or extension cords HDMI This often leads to loss of signal. 4K. Connect the console directly to the TV.
Visually, 4K cables are often labeled "High Speed" on the connector. If you use a long cable (over 2 meters), make sure it's shielded, as Xiaomi TV can be sensitive to interference when trying handshake in high resolution.
Set up HDMI settings on Xiaomi TV
The Android TV or PatchWall operating system interface in Xiaomi TVs requires manual activation of advanced modes for gaming consoles. By default, ports can operate in compatibility mode, which blocks the transmission of HDR and 4K signal from the PS4 Pro.
You need to go to the TV settings menu. Find the inputs section. Depending on the firmware version, the path may be different, but the logic remains the same: you need to switch a particular port to high bandwidth mode.
Where to find HDMI settings in different versions of MIUI TV?
Once HDMI 2.0 or Ultra HD Deep Color is activated, the TV can reboot the video stream, which is normal behavior, indicating that parameters are rematched with the connected device.
☑️ Checking settings HDMI
Activate 4K and HDR in the PlayStation 4 Pro menu
After the TV is ready, we move on to the console settings. The PlayStation 4 system automatically determines the display's capabilities when you connect. If everything is done correctly in the previous stages, new options will appear in the console menu.
Go to Settings -> Sound and Screen -> Video Output settings. The key parameter here is Resolution. Make sure you have "Automatic" marked. If you choose a specific resolution manually, this can cause conflicts when running games optimized for different standards.
To enable advanced dynamic range, find HDR Settings. Select Automatic. The console will run a test and if Xiaomi TV confirms support, the mode will be activated. Similarly, do the Deep Color Output setting by selecting Automatic or YUV420 if color issues arise.
Importantly, some games require a separate HDR activation within their graphics settings menu, and system settings only open up the possibility, but do not force the mode in each application.
Signal diagnostics and testing
To make sure that the settings are successful, the PS4 Pro offers a built-in verification tool. From the Video Output Settings menu, select Video Info. Here you will see the current resolution and HDR status.
If the resolution bar says 2160p and the HDR light is next to it, then the PS4 Pro and Xiaomi are working correctly. If you see 1080p or 1080p HDR, then 4K is not activated.
| Parameter | Value for 4K HDR | Value in error |
|---|---|---|
| Permission | 2160p | 1080p / 1080i |
| HDR | On (On) | Off (Off) |
| Depth of color | 10 bits (YUV420) | 8 bits |
| HDCP | 2.2 | 1.4 |
You can also run a YouTube test video on a console or TV, find a video that's labeled "4K HDR." If the picture looks dull or the colors are unnatural, you may not have the RGB range set up.
Solving RGB range and color issues
A common problem when connecting game consoles to Xiaomi TVs is the incorrect display of black (it turns gray) or over-lit white areas. This is a conflict of ranges: the console sends a signal Full Range (0-255), and the TV expects Limited (16-235), or vice versa.
In the PS4 Pro video output settings, look for RGB Range. Try switching it from Automatic to Full or Limited. Watch the image change in real time.
⚠️ Attention: Wrong range RGB does not reduce performance, but seriously impairs the visual perception of the game, making the picture fade.
On the side of the Xiaomi TV, you can also have image format settings. In the image menu, look for options like "HDMI Format," "Dynamic Range," or "Black Level." Setting the HDMI Black Level setting to the High or Low position should sync the picture with the choice on the console.
Features of working with games and applications
Not all PS4 Pro games support native 4K. Many use Checkerboard Rendering or dynamic resolution, scaling the picture to 4K.
Streaming apps like Netflix or YouTube on PS4 also need to show 4K content if subscription and internet speed allow.However, some apps on Android TV may require 4K activation separately in their internal settings.
💡
For maximum quality in games, always choose the Graphics Quality mode in the game settings if the developer gives you a choice between performance and resolution.
It is worth considering that when HDR is turned on, the brightness of the screen can subjectively change, which is due to the fact that Xiaomi TV is rearranging the tone card to meet the HDR10 standard.
