Hello there. I have a 4K TV. I am thinking about purchasing a Blu-Ray player that offers 4K upscaling. I have some questions, so I'm hoping someone can help! My questions are as follows: 1) Does 4K upscaling work? 2) Does 4K upscaling work on DVDs? I know they won't be upscaled to 4K standard, but I have hundreds of DVDs, and they look rubbish on my 4K TV, so I'm about to sell them or throw them out. However, if an upscaler will ensure they are at least Blu-Ray quality (is this possible?), I will keep them. Appreciate any advice or answers.
