You can check (1) for a swedish conpany selling reasonably cheap TV's without all the smart stuff (they don't even have TV-antenna receiver). They are more or less just monitors with HDMI etc. Perfect for connecting an old linux laptop or something and make it a smart TV on your own terms (btw I'm not affiliated to the company by any means)
