DVDs look terrible on new 4K TV

[Emmett Brown]

Hey everyone,

I'm pretty new to this site. I just recently bought a new 4K TV. The UHD series 6 (6270) samsung TV 50". I've been using a PS3 to play my DVDs and Blu-Rays for years. Although since I got this TV a month ago my DVDs look terrible. I've constantly tried to adjust the settings. I've gone through the Pixar menu calibration setup and my Blu-Rays look exceptional.

Is there something that I can do? No youtube video explaining how to adjust the settings has worked. I know that the image is being stretched based on the size of the TV so that it will pixelate the image. Could it be my player? I have been thinking about getting an all region Blu-Ray player. Would this upscale the DVD transfer? Any model suggestions?

I still watch a lot of DVDs and I just can't accept that they will always look bad. There must be a way!

Thanks
