What's the pros of that signage TV versus any consumer TV? It's still a "smart TV" running Tizen OS from Samsung so high chances of similar software shittyness.
The point of a sign is that it shows what you want it to show. Whether that's an advantage depends on whether that's what you're looking for. But every feature of the display is going to be oriented towards that goal.
Notwithstanding the Amazon review that says "Yes it has wifi", you might find it noteworthy that this model does not have wifi connectivity. (As can be verified from its spec sheet, https://image-us.samsung.com/SamsungUS/samsungbusiness/pdf/s... , or from its page on CDW, https://www.cdw.com/product/samsung-qe43t-smart-signage-qet-... )
Your comments elsewhere in this very thread seem to indicate that this product is exactly what you want, a display that won't show ads and, in the general case, isn't connected to the internet. What exactly are you imagining will happen to someone who uses one?
Having gotten a 40" sibling that was sold as "desktop monitor" with otherwise identical panel (besides of course pixel pitch) spoiled me with it's "technically counts as HDR" native contrast from a burn-in resistant LCD, also suffering just barely perceptible loss of contrast with no significant color shift at all viewing angles that aren't already too extreme to comfortably read text due to distortion.
Sure, it's slow and thus not suited for competitive counter strike, code editing and SDR-mastered visual media look about as good as an LCD can. They do though seem to not consider factory/nominal color calibration for the panel with the signal processor and a regular operating system on an attached PC something they want to offer on these, which is annoying because with 8 bit and the nominal 5000:1 static contrast mild banding isn't even unexpected. So it'd be preferable to just drop an ICC profile onto the computer that's valid for when the screen is set to native gamma and native white balance (I.e. dumb panel mode) and get to make full use of the panel without the excess expense of individually calibrating devices to do digital proofs ahead of actual production/view the material during actively ongoing color grading work. A decent color managed (but not individually calibrated) screen will suffice happily for most tasks, to the point where further calibration won't be perceptible in a double blind test with the screen isolated from reference light sources for most untrained eyes.
