even without shady stuff. it's just common sense. disconnect the 'computer' from the 'display' so you don't need to replace both when the 'computer' becomes obsolete--and it will, usually, before the 'display' quits working. don't connect it. if you want 'smart tv' functionality, get a cheaper and easier-to-replace streaming device of your choice instead.
beware of models or brands you have to go online with just to 'set up'. more and more are 'requiring' internet access and/or an 'account' just to turn on and use as a 'dumb' display.
