HDMI wireless transmitter

[milner993]

ive just bought my first house and want to set up my home cinema in the livingroom, I have an Optoma 1080p projector which I will be mounting on a floating shielf up high I don't want to run my hdmi cable's through the walls so have looked in to the wireless transmitters the signal will not have to go through any walls and the total distance between transmitter and receiver will be no more than 5 feet has anyone used them what are they like my projector will be shooting an image of 92" will the quality be terrible.

Please help
