Some get upset that content is cut off when zoomed so let's skip all that and find out who to ask.
Here I'd go with Sony first. Hit Sony.com and in your country will be a phone number. Call and ask this.
Same for samsung.com.
The makers have for me answered pre-sales questions like this. Stores should too and if they don't, go ahead and make a scene. They can't be allowed to be a seller of boxes only.
I am trying to find a blu-ray player that will allow me to zoom the picture from wide screen to full screen.
Do they make them any more and if so where can I find one
