Since the Asus PB278Q (27 "monitor with 2560x1440 pixels resolution), like many other PC monitors also has only one HDMI input and I did not always umstöpseln mechanically between DVB-T tuner and Google Chrome Cast dongle, I have bought this HDMI splitter. The DVB-T tuner attached to the input 1 (highest priority) and the Chromecast dongle on Input 2 (medium priority). The input 3 (lowest priority) is currently reserve. If the DVB-T tuner is turned on while the Chromecast dongle is active, the HDMI splitter automatically switch to the tuner. If the DVB-T tuner is turned off, the signal of Chromecast dongle is connected to the monitor. Is turned on when the dongle DVB-T tuner the Chromecast which Chromecast Dongel image appears on the monitor again. Short Sharp Shock, the distributor works in this configuration, properly and fully automatic, manual switching of HDMI inputs to the HDMI Selektortaster the distributor is not necessary. Since my DVB-T tuner interpolates the standard TV picture on 1080 pixels (HD-TV) and the Chromecast Dongel 1080 points can from home, the presentation of both sources on the monitor is flawless. A visual difference in picture quality with and without HDMI splitter is not visible. Since I bought the HDMI distribution for under 10 incl. Free shipping and immediate availability, price / performance and functionality with 5 stars are fully justified.
