my 10 year old 75" TV cost me upwards of $70, probably $100, to move across town -- at the cost of the boxes and packing material and labor the movers provided.
When I move again in a few months I think I'll just throw it in the back of my SUV and hope it doesn't break.
I used to run a traveling pro sports league and we transported our own scoreboards.
A bunch of foam pool noodles, a blanket and plastic wrapping tape can very quickly and cheaply get you a padded container that is easy to add handles to.
We shipped boards all over the country in the back of semi trucks with this setup and it worked great.
I moved my large tv cross country twice. The movers build a wooden and cardboard crate for it. Very safe.
Wrap it in a blanket and it'll probably be fine.
In your own car, sure, in a moving van, probably not.
