Yes I found that getting a TV that had a good viewing angle was almost impossible.
I wanted one that I could watch at an angle. Like most RVs you can't watch it straight on. At any more than just slightly the screen will appear black or very distorted.
After 2 tries,one a JVC,the other an RCA,I found that they both were impossible to watch at an angle. So after some research I found one that has a 160 degree viewing angle. I found that the insignia brand had the best ones.
But before buying check it out at the store if possible.
