No, a tv isn't that much different from a large monitor. In the past when we had CRTs and poor EMF shielding TV detector vans claimed to use "van eck phreaking" https://en.wikipedia.org/wiki/Van_Eck_phreaking https://en.wikipedia.org/wiki/Van_Eck_phreaking. They had a couple of actual working vans, but these were purely for technical demonstrations. The rest of the vans were labelled up and they'd drive around to places that didn't have a licence (For a while TV Licencing had the largest civilian database in the UK) and knock on doors. Some of the "inspectors" used, and still use, pretty unpleasant techniques. I'm generally in favour of the licence. I don't need one right now, and I've found it easy to get the letters to stop (I fill out an online form), but some friends get letters almost fortnightly. They have mental ill-health, and they find the letters distressing. It's annoying to me that TVL / Capita aren't better at supressing those letters.
