Having tree stands with toys all over has worked pretty well for us. We have big tree stands in corners and one smaller one on an end table, and they'd rather sit with us than over there so it works. We also have a sound bar over the TV that they don't seem to like.
Blinds and my monitor are a bigger problem since my girl tiel Nuggs is in the office with me most work days, and the boy Smokey is sometimes. For that I got a little 3d printed perch stand with a platform. I wouldn't do it if it's a big TV that gets warm, but for my smaller monitors it works well and catches the poop. For the blinds I use periodic bribes to keep them on the tree stand next to my desk
