Why HDMI 2.1 Matters for PS5 & Xbox
Modern gaming consoles can take advantage of high-refresh-rate 4K gaming when the complete setup supports it. If you own a compatible 4K 120Hz TV and gaming console, using an HDMI 2.1-based TV sync system helps you build a setup around that higher-bandwidth connection.
The Apex HDMI 2.1 TV Backlight supports 4K 120Hz and is designed for modern HDMI 2.1 gaming setups.
For gamers who have invested in a 4K 120Hz television, choosing a backlight designed for HDMI 2.1 makes more sense than selecting a system designed only around 4K 60Hz.

Compatibility: What Can You Connect?
The Apex HDMI 2.1 TV Backlight works with compatible external HDMI devices. This makes it suitable for gaming and entertainment setups using devices such as:
- PlayStation 5
- Xbox Series X
- Compatible gaming PCs
- Amazon Fire TV Stick
- Android TV Box
- Jio Set-Top Box
- Other compatible HDMI output devices
The exact resolution and refresh rate you receive depend on the capabilities of the complete chain: your source device, HDMI cables, sync system, and TV.
Important Compatibility Check Before Buying
Having an HDMI 2.1 TV backlight does not automatically turn a 60Hz TV into a 120Hz TV.
Your TV, gaming device, HDMI cables, and other connected equipment must support the desired resolution and refresh rate.
For example, to use a 4K 120Hz gaming setup, your TV and gaming source must also support 4K 120Hz.
How Does the Apex HDMI 2.1 TV Backlight Work?
The system uses an HDMI sync box to analyse the video signal from an external HDMI source. It detects colours from different areas of the displayed content and sends matching colours to the LED strip behind the TV.
This creates real-time screen-synchronised ambient lighting.
Instead of choosing one fixed RGB colour, the lighting can react to the changing colours and scenes on the screen.
Real Installation Photos
Below are examples from the Apex HDMI 2.1 TV Backlight product installation and product visuals.
Real-time ambient lighting example: the backlight creates a glow behind the TV that follows the displayed content.
The product includes the HDMI sync system and LED backlight designed for installation behind compatible TVs.
What Makes the Apex HDMI 2.1 Backlight Different?
60 LEDs Per Metre
The included LED strip uses 60 LEDs per metre, providing a high-density lighting arrangement designed for smoother colour transitions and fuller illumination around the TV.
Real-Time Screen Sync
The lighting reacts to the HDMI video signal, allowing the colours behind the TV to follow what is happening on screen.
VRR, ALLM & HDR10+ Support
For gaming-focused setups, the HDMI 2.1 version supports modern gaming-related features including VRR, ALLM and HDR10+, helping it fit better into a current-generation entertainment setup.
Smart Life App
You can adjust brightness, colours, and lighting modes through the Smart Life app.
Alexa & Google Assistant
The Apex HDMI 2.1 TV Backlight also supports voice control through compatible Alexa and Google Assistant setups.
InfinitySync
The TV backlight can be part of a larger Apex lighting ecosystem. Compatible InfinitySync products can be added to expand the lighting effect around your room.
Limitations You Should Know
No HDMI sync system is suitable for every setup. Here are the most important limitations to understand before purchasing.
- External HDMI source required: The screen-sync system works with video signals passing through the HDMI connection.
- Built-in TV apps: Apps running directly on the TV, such as Netflix or YouTube, do not send their signal through the external HDMI sync system in the same way.
- Complete setup matters: 4K 120Hz requires compatible source, TV, cables, and connections.
- HDMI 2.1 does not upgrade your TV: A backlight cannot add 120Hz capability to a TV that only supports 60Hz.
- Installation takes some care: The LED strip needs to be positioned properly around the back of the TV for the best lighting effect.
Testing Methodology: How We Would Test an HDMI 2.1 TV Backlight
If you want to properly evaluate an HDMI 2.1 TV backlight, do not test only whether the LEDs turn on. A useful test should check both video compatibility and lighting performance.
- TV compatibility test: Confirm the TV supports the desired resolution and refresh rate.
- 4K 120Hz test: Connect a compatible gaming source and verify that the TV receives the intended 4K 120Hz signal.
- Screen-sync test: Display scenes containing different colours and check whether the backlight follows the screen.
- Fast-motion test: Use fast gaming scenes to observe how quickly the lighting responds to colour changes.
- Brightness test: Test different brightness levels in both dark and moderately lit rooms.
- Gaming feature test: Check the intended VRR, ALLM, and HDR compatibility of the complete setup.
- App test: Test Smart Life app controls, brightness adjustment, colours, and lighting modes.
- Voice-control test: Test compatible Alexa or Google Assistant commands.
- Installation test: Check whether the strip is securely installed and evenly positioned around the TV.
