i have the the computer screen fine on my t.v screen but not my computer. Computer screen just shows desktop background and my mouse will move off to the right and appear on there. I want the image on both so when my t.v is being watched, i can just switch my computer on and everything is there.
also, I did not set this up. Living with my b.f. Hes away and i was hoovering around the wires, so poss loose connection as lost signal for a while. But before he just used to turn the small monitor on and everything was there or switch to hdm1 on the t.v and also everything was there. I have obviously messed something up!
