ever since we get this projector out of the box we have have nothing but trouble . just get it to power on take about 10 minute of button push and connect and reconnect before we can coax it to power up . and sometimes it receive the hdmus signal and sometimes it do not . Technical support from Optoma be just about be poor as tech support can be , with nothing better than a web form to fill out , and a promise they will get back to I in 24-48 hour , by e-mail ! then once they get back to you , you be catch in a very slow e-mail correspondence , and then you give up .
