100" Hisense L5 Series 4K Android Smart HDR Projector Laser TV Expired

No offense but most of this information is wrong.
The TV labeling has nothing to do with it having an OS baked in. It is just Hisense's marketing of their lineup of ultra short throw projector and screen bundles. I have yet to see a high end ultra short throw laser projector that did not have an OS (primarily Android) baked in. It is not a unique feature to this or have any impact on its designation as a "laser TV".
What "upper tier models" are you referring to that include TV tuners? What year is this? This is not even close to a feature that premium models would have.
This is not, "just a short throw projector". It is classified as a specific type of projector called an "ultra short throw laser projector". The difference is that a "short throw" projector requires several feet+ of distance from the screen to throw a large image where a traditional projector would need a lot more throw distance to produce the same size image. An ultra short throw projector is a different category of projector because it can be very close to the surface it is projecting on (sometimes less than a foot), thus the "ultra" differentiation. It is specified as a "laser" projector because of its light source being from a laser generator and not a traditional projector bulb. There are still ultra short throw projectors that use traditional bulbs but have quickly become obsolete with the implementation of laser technology which is why we are seeing a boom in product offerings for ultra short throw laser projectors right now.
All of the light comes directly from the projector itself. There is zero "back-light". The picture is generated entirely from below the screen.
The screen is what is called an ALR screen which means Ambient Light Rejecting. The material has small ridges in it that catch light from below that is being thrown by the projector and rejects the ambient light from other sources. That is how it can look like a 100" TV even in a room with lights on or windows open.

I guess you could say that. I am a woodworker and have always enjoyed home theater. When I convinced my wife to make the switch to a home theater setup, I wanted it to look right and make her happy. We have more of a rustic theme so I built the frame and wrapped it with the projector screen material from Carl's Place. Then I framed in the entire thing with strips of reclaimed wood flooring that I recovered from an old cotton mill that was torn down. The dark of the wood provides a perfect contrast and my wife loved that it matched our home. There is a great amount of support material out there on how to custom build screens to fit your space rather than trying to pick standard sizes. I like to think that I took it a step further by framing it out like I did which is really why I called it custom. Custom size for our space and custom build materials for the look we wanted.

This deal comes up every other week. This is essentially the going price now.
