This projector is just wonderful....I dodn't purchased this on Amazon...but somehow I bought it from an international seller for a good price of around 52k....First of all,you need a big room for this projector,installing a screen or not,is upto you...I personally bought a 12ft*8ft high gain screen...Connected it with my Sony Bluray player & Home theater system...Pros:-*Image is crystal clear,Colours are amazing,Even the darker videos could be seen brighter with help of bright mode bulit in with this projector,A big thumbs up for Optoma.*Has 2 HDMI ports with MHL compatibility(Only 1st port supports MHL) so I can easily connect my Samsung Note 4 to the projector and I directly watch/play everything from my phone.*Inbuilt speaker(10W) is not too loud...But audio is very clear...*3d effect is massive....I've enjoyed a ton watching a 3d film using this projector l.I've bought 2 pairs of Sainsonic 60Hz 3d glasses for me....I didn't tried 3d vesa sync...so I dont wanna talk about it...*Remote control was definitely a pro,it has a backlit display & it's not way too big...it's compact and buttons are very conveniently placed....*Fan is very quiet & projector doesn't heat a lot....Cons:-Not many,but are there...*Doesn't have any inputs to connect RCA cable..If you have set top box without hdmi output you cannot connect to this...Overall,very happy with this guy....My rating-9/10 :)
