Why are the 4K projectors so large?

Hi,
I was looking at the new Sony, JVC and Epson 4K and pseudo 4K projectors and was really taken back with their size. These things are huge, I have a microwave oven that is smaller.

What about 4K requires such a large box?

Thanks

Yeah, I had the same response going from an Optoma 1080p projector to an Optoma UHD60 4K projector, and then to the Sony VW695ES. It was like going from a lunch box size to a suitcase size! Not sure myself but I sure love the picture, so it’s worth it to me!

I can make them fit, but there has to be a physical reason. So you like the Sony? I've had Sony's for years, the JVCs are intriguing -- I'm going to wait to see what Cedia reveals then take the plunge.

I love my Sony! I am a fan of the JVC’s as well. I went with whichever one I could get the best deal on and have been very pleased with my decision.

The large size might be about cooling, and being quieter, while achieving that. Bigger and better multi-glass optics, also mean they need more substantial
chassis.

They are still compact and light weight compared to a 9" crt projector...

True that !!

None of the dealers I've talked to offer any answers. I haven't seen the 4K lasers.

Longer multiple light paths for three chipper pjs also add up.

My guess is that it has something to do with most true 4K projectors are higher end models that are typically bigger due to bigger and better optics, etc.

7.1.4 Theater Room (In Progress): JVC-RS46U, Silver Ticket AT 2.35:1 142”, Onkyo RZ830, Anthem PVA-7, Panasonic DBT-110, JBL Studio 270’s, 4 - 15" DIY Sealed Subs

3.1 Living Room: Samsung 64” F8500 Plasma, Anthem MRX 300, Dynaudio Audience 52’s, Dynaudio Audience 122C, NHT SubOne

They often have larger lenses with more elements to correct artifacts so true 4k resolution is attained, as well as more powerful lightsource for HDR which all translates to larger chassis needs.

There are smaller ones that are less sharp & bright in very compact chassis though like the entry level Optoma & BenQ projectors.

Often the better projectors have a much larger throw range, which requires a larger lens, which requires a larger housing.
