The EZCast Pocket is a product that wirelessly transmits (mirrors) video and audio from devices like PCs and tablets to a monitor. It requires no complicated setup; you simply connect the transmitter (TX) to your PC or tablet and the receiver (RX) to your monitor for easy use. This product uses HDMI connections for both the transmitter and receiver. I have used it a few times after purchasing it, but I no longer find it necessary for my needs, so I am selling it. It has not been used much and is in good condition, but please understand that it is a used item, so please check the photos carefully before purchasing. No claims and no returns accepted.
