AppleTV and projector

[OneQuestionMan]

I will be posting in the projector forum too but I figure some of you folks can help. I don’t have the correct jargon so not sure any of this will make sense.

Anybody here use a projector with their AppleTV?

Long story short - I need to give up my 4K TV for the foreseeable future. I’ve been offered the loan of a new projector as an alternative.

I got briefly test the same model last night to see how it looked. The conditions were not ideal as I didn’t have a screen or a blockout blind. The Mandolorian didn’t look as good as on my HD TV but it was like a being at the cinema - only better than my local as the projection was going out of focus at big movements in screen. I watched a few minutes of other movies and some old movies to see how black & white looks - and they were as good.

The Last Jedi - the lightsabre duel looked good but image was not as good as The Mandolorian.

Rogue One - image was good but not as good as Mando or Last Jedi. Diego Luna’s (and just Diego Luna) costume looked murky and his hair was blotchy.

Mr. Smith Goes to Washington - looked very nice but like Mando, not as good as on my TV

3:10 to Yuma (original) - looked okay. Haven’t watched it on my TV yet so need to compare it tomorrow but I would say just a little better than DVD quality. Not at all as good as on a HD TV.

Blackboard Jungle - looked terrible. On my iPhone and on a HD TV it clean and sharp but on the projector it was it was grainy and murky.

I didn’t have the sense to take photographs and I know that there is a limit to the help and advice they can be given.

It is a HD projector. The brand name is gone out of my head but I will find out. With the right screen or even with new paint on the wall should HD movies look as as they do on a HD TV or iPhone?

The Mandolorian looked the best by far and the image quality in each movie looked so different and Blackboard Junge looked so bad that I’m assuming there was more to it all than the colour of the wall or the light coming in the window (Mando looked good in spite of those). And more to it than adjusting brightness or contrast on the projectorr - if those settings were an issue wouldn’t the B&W movies have all looked equally as bad since they are all they all look equally as good on a HD TV and iPhone? So whatever improvements there would be if I got a screen and blind is not going to magically make Blackboard Jungle look as good as on a HD TV.

Anybody able to give me advice on this?

Cheers
