Well i'm just about to return my third monitor in just over a week to PC world for a refund. KG221Q monitors needed for my xbox on HDMI connection. VGA is fine, HDMI.....no chance. It picks up that there's a connection, but no input. The tech guys checked out the last one and had the same problems. Also the menu options on the monitor not working (only one option allowed me to manually select HDMI input, but nothing else. Tried on xbox, Acer desktop and two PCs at PC world.
Unless im missing something...... but three in ten days is a p. take. Time for a refund and extra work for the re packagers in returns dept.
