Nothing to do with fanboyism.
The technologies are better for different things.
If I was going to get a projector and I likley will at some point. I'd still have an OLED in the same room. I'd set the projector up so it comes down over the wall mounted oled.
You cannot say it's people clinging on to what they know or are used to.
OLED is far superior in every way bar size.
And that is a major issue because bigger is better. It's why in a cinema you have a 200 foot screen for all of you to view versus a 21 inch screen up close.
Both of them are better at different jobs.
I own no less than 15 pairs of headphones and earphones.
Why?
Because they are all good at different jobs.
AKG q701 - gaming and music
Sennheisers HD 600 - music and vocals
Sennheiser HD 700 - gaming
Dt770 - for use when someone else is in the same room or lots of background noise
Xm3 - for use on planes because of the noise cancelling
In ears - used for public transport
Wireless in ears - used for the gym but poorer sound quality when compared to wired in ears.
You cannot use akg 701's on a plane or on public transport. We'll you could just that you would get a lot of people complaining or giving you looks and you would be able to hear all the crap in the background.
OLED and a projector for me. To pick just one is compromising.
I'd use the oled for day to day stuff like watching the news, gaming, etc.
I'd use the projector for special occasions and football and movies.
I dont know which I'd watch a TV series on I'd have to have both to see what suited it best.
If anything the people that only have projectors saying they are great at everything they are the fan boys who can't take any criticism.
When I had an Epson 9400 and a 65'' OLED, I used the projector for virtually everything.
Sports, films, video games all felt substantially more epic on a 100'' screen rather than a 65'' one. For casual viewing, it was really nice as everyone had a good view of the screen as its so massive.
With the 77'' OLED, I do find myself preferring gaming on that though because video games benefit hugely from contrast and the colour black... But I've sadly never had in my room a top tier projector like the NX5 or NX7 which would have black levels and a contrast which could shine.
I much preferred watching the Sopranos on the projector. Felt lovely. You can appreciate little details so much better than on a small, cramped screen.
I remember the Lion King 4K HDR on the Epson was incredible because I could see the individual hairs on Simba in the starting sequence. On a TV, everything just looks sharper, but on a projection due to the incredible size, you don't think 'wow this is sharp', you think 'wow I can see this specific detail'.
Another very incredible part of the Epson was 3D. Wow.
I've heard DLPs are better for 3D so I have been edging towards trying to find a cheap, very bright 3D DLP projector to tide me over.
Also, if you're only going to use a projector for special occasions, I think it will be hard to justify dedicating a big portion of your budget to a projector and screen if the TV gets more use.
