Function: This product can be used as a signal router, allowing you to connect one HDMI-capable device to two separate display devices. You can watch TV in one room and, when desired, switch to another room by turning off the first TV and turning on the second TV to route the signal accordingly. Ideal for connecting a single HDMI source to two displays. Supports HDMI devices with built-in HDMI ports, such as HDTV, PlayStation 3, upconverting DVD players, LCD monitors, and projectors. Features gold-plated connectors for improved signal transmission. 1 In 2 Out HDMI Splitter supports 4K resolution. Only one output device should be active at a time unless both displays are identical; otherwise, both may display images when connected. Note: Measurements are manually taken and may vary by 1–3 cm. Color may vary slightly due to lighting and display settings. Delivery quantity as shown in the main image.
