Hi,
I'm about to get my first PJ and screen to install in my lounge (very excited!

) and I've currently got my electrician installing HDMI and speaker cable into my lounge ceiling before the plasterer comes in.
I haven't got my screen yet though and I'm unsure about power I'll need and where. Is it a just fused spur in the top of the wall near the end of the screen casing?
I'm probably going to go for a Realm 200cm tab-tensioned screen, does anyone have one who can help with the power requirements or point me to website where can I get the info please? (I've tried, but can't find anything)
Thanks very much in advance,
Simon
