HDMI 2x1 Multi-Viewer, a 2-screen splitter. My purpose for buying this was to split the screen because I only have one TV and wanted to watch TV while playing games. Specifically, I bought it to watch TV while automatically running a game, as it would violate the game's terms of service if I left the screen while using macros to automatically move my game character. While it did achieve my purpose, I no longer play games, so I no longer need this device. While using this device, the game's background music played, but I sometimes couldn't hear the character's dialogue. The cause is unknown, possibly due to the TV's speaker performance, and I don't think it's a malfunction. The included accessories are all shown in the images, and a Japanese instruction manual is also included. An HDMI cable is not included. Please understand that this is a personal item and has been inspected by an amateur, so there may be unnoticed dirt or scratches. Due to recent return troubles, please purchase with no claims and no returns. I am not accepting price negotiations, but I plan to lower the price at my own discretion, so please purchase at a price you are satisfied with. Shipping is planned via "Yu-Yu Mercari Delivery," but please note that other shipping methods may be used.
