Buying Guide & FAQs
Everything you need to know before buying your Apex Light product.
Yes. The Apex HDMI Sync Box 2.1 supports up to 4K 144Hz, depending on your source device, display and HDMI cable capability.
Most gaming consoles such as PS5 and Xbox Series X typically run up to 4K 120Hz, which is why we mainly highlight 4K 120Hz in our marketing. However, if you are using a higher-refresh-rate gaming PC or another compatible source and display, the Apex HDMI 2.1 Sync Box can support up to 4K 144Hz for an even smoother gaming experience.
Note: To achieve 4K 144Hz, your source device, TV/monitor and HDMI cable must all support that resolution and refresh rate.
Apex TV Backlight connects to the HDMI 2.1 Sync Box, which analyses the video signal from your external HDMI device. It detects the colors displayed in different areas of the TV screen and sends matching colors to the LED backlight in real time, creating an immersive lighting effect behind your TV.
The included backlight uses a high-density strip with 60 LEDs per meter, designed to provide smoother color transitions and fuller illumination behind the TV.
Yes. Use the Smart Life app to adjust brightness, choose colors and switch lighting modes.
