I just bought a new mac mini i3 last night. I have it hooked up to a 32 inch samsung LED tv. Everything is ok until the screen saver tries to come on and then the tv reads 'no signal' and the mac requires a button press for the screen to reactivate. Ive tried everything from changing the input name on the tv to pc and making sure power saving is switched off. Starting to think there isnt much I can do but I thought id ask the smart folks here and see if anyone else has had a similar issue.
