My Awful Experience with Philips Smart Television

I'm not happy with my Philips Smart TV at all. It's so slow that I've never seen a TV like it before. It has Smart TV features, like being able to watch YouTube.com, but it's very slow. But I can't add any more apps, and when I press a button, it takes between 5 and 10 seconds to respond. I haven't watched TV for the past 4–5 years because it has been so disappointing. Now, I want to project my computer screen onto the TV, but I'm not sure if that's possible because basic functions don't seem to work. I don't understand why Philips would sell something like that. I'm writing this review to warn other people who might want to buy Philips Smart TV to stay away from it.
