If money's not a factor? Maybe a Linux Panel PC.

I've tried a few Lenovos and they seem ok - inc. the Lenovo Thinksmart discussed on the HA forum

All tablets have a quirk somewhere, but FullyKiosk does a good job - if the tablet is any good - so I recommend it. A colleague used something else.. I'll try to find out what it was.

Whatever you do get, if it has a battery, ensure you monitor it's battery and keep it somewhere between ~20% & ~80% with a smart power socket / USB relay

Based on your statement that you've only had this for a few months, my suggestion is to assume you'll want to change it in 1~2 years, so try cheap, named brand, 2nd hand ones from ebay until you get size and rotation right for how you use it.

My dashboard on the kitchen tablet is landscape, but portrait in the lounge (on the ThinkSmart on a coffee table) - both seemed too big initially, now they feel too small.
