The OREI HD-102 is a reliable distribution amplifier powered splitter that will take HDMI signal up to 4K@30Hz and duplicate the signal to up to 2 HDMI displays simultaneously, creating an impressive lossless image or audio transmission via HDMI cable. Compact, durable and easy to setup and operate. Ideal for trade show, conference room, lecture halls, bed room, living room, kitchen room and backyard. Please note that this splitter will duplicate the source to the two output displays. It can't be used to extend a desktop for PC or a laptop. If the connected displays do not support the same resolution then the splitter will lower the output resolution to the next best resolution supported by both displays and same goes with the audio signal. We recommend using this splitter with high quality HDMI cables 30 feet or less.
