A while ago, I was looking to buy a "dumb tv". In the end I narrowed it down to professional display, computer monitors, and projectors. And sadly, the prices are usually higher than a TV of the same size.
Professional Displays are those you find in fast food with the menu, or in offices with info, doctors etc... One of the reasons they are expensive is because they are made to be on 24x7.
Projectors are cool, but they work better in darker rooms. The cheaper ones also need more space from the wall.
I ended up going with a computer monitor, LG ultragear 48 inches, it is great. And it was cheaper than anything else, and I was lucky there was a price drop from the MSRP because they were restocking to a newer model. Usually they are a bit more expensive than the equivalent LG C model TV.
With a monitor, you will have to plug anything that you want to watch, there is no wifi and apps. Another constrain is size, the largest I could find were 48 inches. Anything bigger would fall into the professional display category and get expensive fast.
Sadly, I just checked online and neither Amazon or Best Buy are offering those here in Canada https://www.bestbuy.ca/en-ca/product/lg-ultragear-48-uhd-138hz-0-1ms-gtg-oled-lcd-freesync-gaming-monitor-48gq900-b-black/16310839. LG was usually around 1k CAD, and BenQ was not that far off.
I hope it is just shortage rather than discontinuing those line of products.
