What are these options?! - Philips 43pus8309

Hey everyone,

I'm a little lost here. I just bought a budget Philips TV (name in the title). I know it's a cheap TV, but I am still quite confused about one rather important thing.

Why can't I adjust anything?

I found the options menu and wanted to start adjusting there settings, but there is very little I can adjust. Also, I can only access the options menu from the start screen, it won't open when I play a movie or game on the back. Changing anything also doesn't seem to affect anything. My options also change based on which hdmi port I use, I can't change this, at the same time when using my Xbox it randomly changes into game mode, but I can adjust any of the settings in game mode.

I am very confused, haven't had this problem with any TV I've ever owned.

My TV came with a 3rd party remote, maybe this is one of the reasons why I can't enter the settings outside of the main menu?
