Hi @Anonymous User
I believe there is no manual option to select 4:3 aspect ratio because from the nowtv generation black box onwards where these devices assume that people are using a modern widescreen television,
The only nowtv product that offered the option in the menu to select 4:3 aspect ratio was the first generation white nowtv box.
What Type of TV are you using with the stick i,e. old CRT TV or Widscreen TV ?
What TV shows or Movies you think is not natively streamed properly in the correct aspect ratio on NowTV and looks wrong to you ?
Have you had a play around with the aspect ratio options on your TV ?
If you are trying to watch an old broadcasted TV show that was filmed in 4:3 ratio and have the black vertical bars on each side of a 16:9 windscreen TV then the only way to get rid of the black bars is to zoom in the picture on your television (not recommended where the picture will look stretched).
