As noted elsewhere, broadcast hardware has much higher manufacturing and performance requirements, so it's not an apples-to-apples price comparison.
I'm sure there's a market for $600 (or $1000) TVs that don't have all the "price-lowering" (I'm skeptical) features of $300 TVs.
I mean, maybe the prices of ad-TVs are so low as a loss-leader to get a new advertising vector into your house? Yes, of course TVs already have ads, but they don't have thisparticular pipeline, one that benefits the manufacturer/brand more than normal OTA ads.
How much is a less-annoying TV worth to people? I'm guessing more than is usually estimated, and at any rate probably pretty close to price+ad revenue of a "consumer display."
The last time I bought a TV, >10 years ago, a high end, but not top of the line quality dumb TV was ~$1000. I'd gladly pay that again, especially if I think it's going to last 12 years or so.
I think that's a different product/market? Aren't those displays targeting high end video/movie production that requires perfect color correction? I'd also guess they're marked up a lot given their customer (movie studios/enterprise). They're also small.
I think there's a middle ground 'good enough' panel that's still high end (think like LG E6) that doesn't have the extra crap and where someone has thought through the design elements (input box, remote, industrial design of case).
I'd expect that to be possible for around $5k - maybe that's just not feasible?
Are they really that expensive? I looked up the device that I probably would want, and that would be the 55 inch 4k TV. Searching for a place to buy it revealed this link, that gives a price: https://www.uk.insight.com/en-gb/productinfo/lcd-tvs-and-dis...
It seems pretty reasonable to me. Is there a catch with that device that makes it not appropriate to use as your main TV?
Unlike the broadcast OLED displays, those Bravias use normal LCD panels. They're closer to consumer TVs, but lack the TV tuner for legal reasons.
If you're just using it over HDMI, it would work fine as a main TV. The added brightness would may be appreciated.
The gotcha is that it already runs an outdated version of Android(9.0). Sony consumer TVs that released back then didn't have ads. It was only a later Google update that added ads to the UI.[1] No guarantees these signage displays will be safe if you updated them over the internet.
The included ads, large volumes, and low margins all drive down the cost of consumer displays. Your dream might also end up quite expensive. [1] https://pro.sony/ue_US/products/broadcastpromonitors
