> The power of consumer protection agencies is way too low
In the UK, if they advertise them as working with / connecting to a computer, there's no way you aren't getting your money back.
Consumer protections in this country are pretty solid for this sort of thing (thought sadly not the case for new expensive things like cars, new build homes, etc).
I had PC World try to screw me with the old display panel switcheroo on a first gen flat screen Samsung LCD in the 2000s, a £1000, 32" screen which was supposed to have a "new" chevron pattern to the sub-pixels. Store display and review models had it, and it was all over their advertising, mine were plain old squares.
Trading Standards / Citizen's Advice Bureau had them practically begging me to take a replacement mere hours after an outright refusal to replace a TV I'd been using for a year already.
