Best results

You won't see as drastic a result when working with higher resolution sources (PS4 Pro, etc.), but if you are playing a sub 1080p game on your 4k tv, these cables can do wonders to clear the picture up!

The result is amazing!I set the TV resolution to 720p and use mCable to scale up to 1080p

Maybe you could get good results with certain pieces of great retro-focused AV equipment like the Framemeister or OSSC, but I don't have any of those to test.

For best results, go into your TV Mode settings and force the resolution one step down from what your display is

There's some setting involved but the result was great as well
