Why all new things from 8.1. doesn't work at my WP 8X?

[Windows Central Question]

I have a HTC 8X phone and install a new 8.1. version. One of news of this version:
Tile background on Start screen- Tiles fit together like puzzle pieces to display the full image.
I have read a manual, but it doesn't helps. I can make all what is writting, but at the end - black screeen
Background photo on lock screen I cant change too.

Could u show some screenshots?
Its usually as simple as going start+theme and clicking choose photo.

It is indeed "easy" but please see also below link.

And be aware that if you have an "empty" space on the start screen you also will not see the picture and if the app till is not transparent you also will not see the picture.

Yes,
There are a screenshots.
I choose photo, but I dont know where can I see it.

 

[Harrie-S]

Okay I already see the " problem"
In Settings > ease of access > you enabled "high contrast".
If you disable it you will see the background picture
.

 

[Athull]

Yep, that looks exactly like when high contrast is on.
Maybe it was enabled accidently or u did it on purpose and forgot about it.

I never do that without your help.
Now I see all!!!
