android box

HI all. just got a new quad core box but it keeps flashing off and on when connected to my big tv but is fine on smaller ones upstairs,the box itself doesn't turn off so i bought a new HDMI lead but still happening ,any ideas? cheers
 
if its running kitkat 4.4. Go to settings > then display look for HDMI auto-detection, It may be selected to auto-detection ON, if so, turn off and select the box below " HDMI Output MODE" change settings in there to a different setting. EX. 720, 1080. The HZ can vary 50HZ 60HZ etc,.,,

If the HDMI Auto-detect was already off, turn it on.


Hope that helps
