I'm surprised it doesn't mention "sharpness". It's tricky find the zero point: e.g. '0', '50', or '100' depending on whether it means 'add sharpening', 'smooth/sharp', or 'remove smoothing'.
Yeah, that’s often inconvenient. There are test images like http://www.lagom.nl/lcd-test/sharpness.php one can use for testing this. A USB stick with some test images can be useful.
This is a frustration shared with some monitors, too. Either the zero-point should be obvious or there should be a toggle that disables the setting altogether.
Agree with sharpness, I undo this on every TV I get a chance to touch at friends/family.
You really go around to people's homes and change their TV settings?
As in I randomly knock some doors, ask to come in, find their TV, then their remote, then change settings to my liking and leave?
Not all heroes wear capes.
I mean sure, if that's your style. Personally I carry a universal remote for when I'm doing this.
I only do it for TVs that are accessible to my universal remote that I can see from outside the windows, that way I don't need to disturb the families
"Excuse me sir, Do you have moment to talk about your TV settings"
I once fixed the remote at a brother-in-law's place. Came back a week later and changed channels using the remote. He shouted "You mean it's been working the whole week and I've been on my knees changing channels?!"
