After years of drooling over home theaters, I am finally on my way to build my own system! I have to make a decision though that is really troubling me and I would really appreciate your help.\n\nI have a 4m (Width) by 6m (Depth) space where I can fit a projector screen up to a maximum of 110 inches (there is a door on the 4m wall so I can only take advantage of 2.7m including enough space for my speakers) or the biggest TV I can afford which is 86 inches. I have already read countless articles about TVs VS projectors and posts on forums but I still can't make up my mind because most of them are referring to 65 to a max of 75 inch TVs.\n\nWhen it comes to ambient light I will be able to fully control it, even though there are quite a few windows in my space, since I will have blackout blinds. The main use-case will be watching movies but I will also be watching series and possible do some or a lot of casual gaming (I have never played any games on a screen other than a PC monitor so I don't know if it will be my cup of tea) and this is what troubles me.\n\nLED TVs have a lifespan close to 100K hours nowadays so I can watch any content without worrying about a time limit unlike the lamp of a projector. If I was only going to watch movies I wouldn't have been bothered about it since you can only watch a movie per day (an average of 2 hours per day) but with series and gaming things are different. I am sure you know how it is with series and how addicting they can be if they are good, same goes for gaming since it's quite easy to lose track of time. I don't want to have to worry about changing lamps every year or less because even though I saved up money for an expensive projector, I can't afford to replace the lamps every 2K hours... Also, the more you use a lamp projector the more the quality is degrading so can you really justify using a projector to watch series or play games based on your experience? I mean, you don't use a Lamborghini to go shopping if you know what I mean...Or do you??? On the other hand, everyone is talking about the amazing experience of a huge screen but you can't really call an 86 inch screen small... Will 20-24 inches make a big enough difference to justify buying a projector and live with it's drawbacks (Closing the blinds every-time you want to watch something, lamp life, brightness\/contrast, input lag)?\n\nThe second thing that troubles me is the Projector vs TV picture quality. I have never seen a home theater projector in action, my only experience is with the horrible low res projectors used in classrooms, so I don't know what to expect and even though I watched several youtube videos I can't really tell how good it is... Based on your experience, can a decent 4K projector be equally good to a LED TV when it comes to picture quality?\n\nWhen it come to budget, 4000€ is the absolute max I can spend and based on that I am between the new 86 inch LG nanocell 900 series which will cost me 3700€, the 85 inch sony KD-85XH9096 at 3600€ or the Optoma CinemaX P1 at 3900€. I have never seeing any of these devices up close and I do not know how good they are quality-wise so I would really appreciate your feedback. From what I hear, sony uses better processing but the LG own has a better UI. I also heard that this year's nanocells are as close to OLED as LED can get. Finally, I chose the Optoma P1 because it was the only UST 4K laser projector with good reviews and for my use-case a lamp projector will just not be enough, even though there are some really good budget lamp projectors such as the new Epsons... Epson also has a 4Kish UST laser projector priced at 2800€ but there are not many reviews online and the ones I found where not very kind to this projector.\n\nJust to be clear, I am more than willing to live with the projector's drawbacks if the extra inches make a big difference, what I truly care is the best Movie\/series\/gaming experience (in that order) for my space and budget. I also don't care about satellite TV or watching sports which would make the TV more appealing. \n\nFinally, I have been trying to find how much it costs to replace the laser on the optoma once it burns out but I can't find anything online.
