TCL is rolling out a major firmware update to its Google TV sets, bringing with it the latest android 14 operating system and, notably, HDMI 2.1 Swift Media Switching (QMS) technology. The update, designated v590 (or v313 in the US), is currently available for manual download and will soon be distributed over-the-air to compatible models in phased releases. This upgrade aims to improve both the software experience and picture quality for TCL television owners, particularly those utilizing modern streaming devices and home theater setups.
TCL is rolling out a significant update for its Google TV sets, bringing a number of improvements including a jump to Android 14 and, notably, HDMI 2.1 Quick Media Switching (QMS). The firmware, identified as v590 (or v313 in the United States), is currently available as a manual download and is expected to be distributed over-the-air (OTA) to compatible devices in phases, varying by region.
The update is more substantial than typical maintenance releases, offering image processing enhancements alongside the operating system upgrade. For users of Apple TV 4K, external players, or those utilizing automatic frame rate switching, the inclusion of HDMI 2.1 QMS is expected to be a particularly welcome addition.
The update is specifically designed for TCL models equipped with Google TV and powered by the MediaTek Pentonic 700 chip. While a number of popular series are included, compatibility may vary depending on the specific market and model variant, as TCL often uses different names for similar products across different countries.
HDMI 2.1 QMS: A Smoother Viewing Experience
Quick Media Switching (QMS) eliminates the black screen that often appears when a television switches between different refresh rates. For example, when moving from a 60Hz menu to a 24Hz movie, QMS enables a smoother transition, minimizing disruption. QMS is designed to provide a more seamless experience for viewers.
To ensure optimal performance, devices supporting QMS should be connected directly to the TV, rather than through an audio/video receiver (AVR) or soundbar. Any intermediary device can potentially interrupt the signal and negate the benefits of QMS. The setting can be found under External Inputs in the TV’s settings menu (Settings > Channels & Inputs > External Inputs).
Android 14 and Enhanced Image Quality
The upgrade to Android 14 provides a more modern and future-proof base for TCL’s Google TV sets, offering improved longevity and features like power modes and picture-in-picture functionality. TCL is releasing this update ahead of its 2026 models, which will ship with Android 14 pre-installed.
In addition to the OS upgrade, the firmware includes a “Super Resolution” option within the image clarity settings, as well as HDR conversion capabilities. These features aim to enhance the quality of lower-resolution content, such as broadcast television or streaming video, though their effectiveness will depend on TCL’s implementation.
Users should exercise caution when enabling these image enhancement features, as overly aggressive settings can sometimes result in an artificial or “over-processed” look. Fortunately, the options are designed to be user-adjustable, allowing viewers to customize the settings to their preferences.
Compatible TCL Models
According to lists circulating online, the following TCL models with Google TV and the MediaTek Pentonic 700 chip are expected to receive the update (regional and naming variations may apply):
- TCL C8K
- TCL QM8K
- TCL C7K
- TCL QM7K
- TCL C6K
- TCL QM6K
- TCL C855
- TCL C845
- TCL QM851G
- TCL C805
- TCL QM751G
- TCL Nxtvision (Photoframe/Art Store series)
If the update delivers as promised, it represents a worthwhile upgrade for compatible TCL televisions. The combination of Android 14, improved image processing, and the potential benefits of HDMI QMS – particularly for users of external streaming devices – make this a significant release. This update is a strong indicator of TCL’s commitment to improving the user experience on its smart TV platform.
TCL owners with compatible models should expect to receive a notification when the OTA update becomes available. The update offers a modern software base, enhanced image features, and a potentially smoother viewing experience with compatible hardware.
