I've recently purchased an OTT TV MXQ PRO box and have had several problems...... Many of the apps installed don't work at all and some partly work, The picture is only showing on the top left quarter of the tv screen 95% of the time but 1 or 2 show full screen, I have been into settings and it is possible to stretch the picture to approx half the screen but then other things are pushed off the screen which makes using the home page impossible, it's driving me mad......HELP!!!
