Sony X900H TV bad news: two important selling points cut off. Quietly revised the X900H TV manual and cut off the VRR and ALLM functions

Sony X900H (National Bank X9000H) is Sony’s main high-end TV launched in 2020 and is considered one of the best LED TVs on the market.

As an excellent partner for the next-generation host, a major feature of X900H is to support HDMI2.1 interface. The official promised that it will openly support 4K/120Hz, VRR (variable refresh rate) and ALLM (automatic low latency mode) through firmware upgrade.

In October 2020, X900H finally added the 120Hz function, but the picture was blurred, and VRR and ALLM still did not support.

VRR can adjust the refresh rate of the display device to reduce the delay, freeze, tearing and other phenomena of the screen, so that the player's experience during the game is smoother.

ALLM automatically turns on the function by automatically checking whether the TV supports "Game Mode", thereby reducing the delay of the game screen.

According to Sony’s recent manual changes, Sony cancelled the VRR and ALLM functions.

Of course, Sony has not officially confirmed the cancellation of VRR and ALLM support for the X900H series, but the revision of the manual may have released an early signal. Be cautious if you plan to start for its HDMI 2.1 interface.
