VIA Labs introduces VL605 USB-C to HDMI 2.1 Converter, Expanding Connectivity Options

Via Labs, Inc. (VLI), a important supplier of USB4, SuperSpeed USB, USB Power Delivery Controllers, and now Display Controllers, has announced the commencement of mass production and immediate availability of the VIA Labs VL605 USB-C to HDMI 2.1 Protocol Converter. This converter has achieved USB-IF certification for USB Power Delivery 3.1 with Extended Power Range (EPR) support, as well as HDMI 2.1 FRL certification. It has been listed on the USB-IF Integrator’s List under TID: 10462.

The VIA Labs VL605 is an innovative single-chip USB-C to HDMI 2.1 Protocol Converter that offers modern display features and a highly integrated, low-power design. It is specifically optimized for USB-C video dongles and multifunction docks, featuring a two-port USB PD 3.1 controller that supports pass-through charging at up to 240W when EPR is enabled. With just a single VL605, users can convert a DisplayPort input to HDMI 2.1 at resolutions of up to 8K@60Hz or 4K@240Hz, all while charging the connected host device. The VL605 also supports HDR and is compatible with Adaptive Sync from the DisplayPort standard and AMD’s FreeSync technology, seamlessly converting these features into HDMI 2.1’s Variable Refresh Rate (VRR).

Products incorporating the VL605 Protocol Converter can enhance gaming experiences by delivering higher quality and smoother visuals, while also expanding peripheral connectivity and enabling faster charging. As mainstream home game consoles and computer hosts increasingly support HDMI 2.1, displays with HDMI 2.1 enhancements such as higher resolution, refresh rate, VRR, and HDR support have become more common. HDMI 2.1 offers a significant bandwidth improvement over HDMI 2.0, with up to 48Gbps compared to 18Gbps, enabling higher 4K refresh rates of 120Hz, 144Hz, and even up to 240Hz with Display Stream Compression (DSC). The VRR feature of HDMI 2.1 dynamically adjusts the refresh rate based on game conditions, resulting in smoother gameplay with reduced screen tearing and perceived input lag.

The VL605 Protocol Converter’s integrated DisplayPort receiver supports HBR3 data rates of up to 32.4Gbps in 4-lane mode. The HDMI source supports both FRL and TMDS modes, with peak bandwidths of 48Gbps and 18Gbps, respectively. It also supports various color formats, including RGB and YCbCr, as well as surround sound audio with up to 8 channels of LPCM at 192kHz, in addition to other compressed audio formats. The VL605 features a built-in DSC decoder and supports Autonomous Mode and Source-Controlled Mode as outlined in the latest DisplayPort 2.1 specification, providing signal sources with enhanced control capabilities. Furthermore, the VL605 can perform secure firmware updates and protect against malicious firmware code attacks by leveraging the built-in security engine supporting ECDSA verification.

Wayne Chang, Director of PM at VIA Labs, highlights the adaptability of the VL605 Protocol Converter. “DisplayPort and HDMI are the industry’s leading video standards and are intertwined with the USB-C ecosystem. When combined with VLI’s diverse USB Hub controllers, the VL605 can create a multitude of USB-C multifunction dock applications with USB PD charge-through function at different USB speeds, enabling a wide range of products. Future demand for VL605’s capabilities is bright. As the latest mobile chips from Apple, Qualcomm, and MediaTek introduce hardware Ray Tracing capabilities, AAA games are being adapted for mobile platforms. With the VL605’s dual USB PD ports and HDMI 2.1 output capabilities, a mobile phone can not only serve as a handheld gaming device but also seamlessly transition into a gaming console at home. It can charge the phone while projecting to a large 4K/8K TV screen, supporting a new gaming experience.”

The VIA Labs VL605 USB-C to HDMI 2.1 Protocol Converter is currently available and shipping in quantity.

VRR: Variable Refresh Rate (VRR) is a technology primarily used in displays, such as computer monitors and televisions, to improve the viewing experience, especially for gamers. VRR synchronizes the refresh rate of the display with the frame rate of the content being shown. VRR technologies, like AMD FreeSync and NVIDIA G-Sync (for PC monitors), and HDMI VRR or VRR through software updates (for TVs and gaming consoles), allow the display to adapt its refresh rate dynamically to match the frame rate of the content. For example, if a game is running at 45 frames per second (fps), the display will adjust its refresh rate to 45Hz, eliminating tearing and reducing stuttering.
