Yes it’s quite common, you need to adjust your TV settings to match your PC. Try putting the same photo up on each screen and get them as close as possible. A while back I bought a Vizio TV to replace my old one and no matter what I did I could not match the settings. I had to take it back and get a different TV.
I like the second shot of the Cadillac and nice work with the Camaro too!
My favourite has to be the last shot. However there is a few things that would be changed by me, which includes stuff like a higher exposure and contrast.
