Sizes have grown since the small TVs of the 1940s which were only a few inches -- usually less than 10 inches in those days!
And CRT tubes never grew beyond about 40" by the 1990s.
In that context, direct-view TV size growth over 30 years from 1990s to 2020s was scorching fast compared to the 50 years between 1940s through 1990.
There is somewhat of a geometric cost growth at 85" and beyond, to the rareified stratospheres, but there are niche 100"+ size options that can be obtained by special order -- not via Amazon or Best Buy. They are by special appointment, like purchasing a yacht -- e.g.
Samsung WALL TV, which is a home MicroLED jumbotron, essentially.
Projectors give 100" for cheap
Going bigger is easier and cheaper to do with a projector. Why not get a $200 electric retractable screen and a $1000 4K projector, and live your 120" nirvana? I've got a few projectors here as well.
Higher End 240 Hz Gaming Projectors Capable of 100 Inches
There are also some low-lag gaming projector options (including
a great 240Hz Optoma projector for a bit of a cost premium). That's still cheaper than a 65" OLED television which cannot even do 240 Hz.
Budget Projectors
If you're tight on money, and don't mind a bit reduced LCD contrast over good DLP contract -- there are cheap chinese-brand native-1080p projectors capable of 100" sizes for between $200-$300. (e.g.
Vankyo V630 or
YABER Y21 projector (these are sometimes on sale for less than USD$200). These cheap native-1080p chinese projectors are a still a sufficiently wow experience because of the massive screen sizes achievable for really cheap -- only a few dollars per inch. Some are very laggy for gaming but gives you a 100 inch experience in a darkened room. You cannot buy a 100 inch direct view TV for this cheap elsewhere.
Cheap Electric Hideaway Projector Screens To Hang By Two Hooks From Ceiling
Being in Canada, I purchased
this basic CanadianView 120" projector screen which uses a remote control to retract itself automatically. There are similiar
Motorized Projector Screens on Amazon USA too. Can be mounted on the ceiling in front of your existing entertainment center, so you can reuse your same TV room. These are about $200-$300, perfect for houses with no walls to use a projector on.
So there you go. Your ticket to 100 inches and bigger.
