The LG CX is a high-end OLED television that was released in 2020. It has a number of impressive features, including support for HDR content, Dolby Atmos audio, and HDMI 2.1 ports. In this answer, we’ll take a closer look at the HDMI ports on the LG CX, what they’re capable of, and how you can make the most of them.
The LG CX has four HDMI ports, which are all located on the back of the television. These ports are labeled HDMI 1, HDMI 2, HDMI 3, and HDMI 4, and they each have slightly different capabilities.
HDMI 1 and HDMI 2 are both HDMI 2.0b ports, which means they’re capable of supporting 4K resolution at 60Hz. They also support HDR10 and HLG (Hybrid Log-Gamma) HDR formats, as well as HDCP 2.2 content protection. Additionally, they both support eARC (Enhanced Audio Return Channel), which allows you to send high-quality audio signals from your TV to a compatible soundbar or home theater system.
HDMI 3 and HDMI 4, on the other hand, are HDMI 2.1 ports. This means they’re capable of supporting higher resolutions and faster refresh rates than HDMI 1 and HDMI 2. Specifically, they can support 4K resolution at up to 120Hz, as well as 8K resolution at up to 60Hz. They also support the same HDR formats as HDMI 1 and HDMI 2, as well as HDCP 2.3 content protection. Additionally, HDMI 3 and HDMI 4 support a number of other features that are unique to HDMI 2.1, including VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and QMS (Quick Media Switching).
VRR, or Variable Refresh Rate, is a feature that allows the refresh rate of the TV to match the refresh rate of the content being displayed. This helps to eliminate screen tearing and other visual artifacts that can occur when the refresh rates are out of sync. ALLM, or Auto Low Latency Mode, is a feature that automatically switches the TV to its lowest input lag mode when it detects that a game console or other device is connected. This can help to improve gaming performance by reducing input lag. Finally, QMS, or Quick Media Switching, is a feature that reduces the amount of time it takes for the TV to switch between different resolutions and frame rates. This can help to eliminate black screens or other interruptions when switching between different types of content.
So, what does all of this mean for you as a user? Well, if you’re planning on using your LG CX to watch movies and TV shows, then you’ll likely be using either HDMI 1 or HDMI 2. These ports are more than capable of handling 4K HDR content, and they also support eARC if you want to connect a soundbar or home theater system.
If you’re a gamer, on the other hand, then you’ll want to take advantage of HDMI 3 and HDMI 4. These ports support higher resolutions and faster refresh rates, as well as a number of gaming-specific features like VRR and ALLM. If you have a gaming console like the PlayStation 5 or Xbox Series X/S that supports HDMI 2.1, then you’ll definitely want to connect it to one of these ports to get the best possible gaming experience.
It’s worth noting that while the LG CX has four HDMI ports, you may not need to use all of them depending on your setup.
