HDMI blackouts?

Hello, i hope someone can help with this problem, so far all the experts have failed. When i plug in my laptop to the flatscreen to watch a film it's ok for a while then the big screen goes back, it starts to reoccur with greater frequency. What i have found is if i unplug and replug the cable it lasts really well most of the time. i thought it may have been a capacitance issue but the fact is its pretty good once replugged. What can i do?

Not knowing your big screen mfg hard to get detail help from someone
with direct experience, and say if USB or other link .

Seems obvious the big screen has a timeout you have not disengaged.
