1 - You and your friend need to make appointments with an eye doctor, stat.
2 - A PS4 Pro cannot upgrade 1080p source material and make it look as good as native 4K content. That is just lunacy. That is like saying a PS3 can make DVDs look as good as Bluray, or a Plasma TV can make PS3 games look better than PC. (Arguments clowns have made on this board before and paid the price)
3 - Your source is beyond stupid
I can’t believe what I’m reading here...
What the hell is going on? I am a PC gamer and like my PS4, but sometimes people make themselves look stupid. I have a 4K TV and the blu-rays do not look near as good on the PS4 as a UHD does on my 4K UHD Samsumg. lol
Again how is this beyond stupid? I NEVER said that the PS4 Pro's blu-ray upscale ability was better or the same as a regular 4K blu-ray, but it is very close. There are countless videos online that do comparisons- I suggest that you watch them. The PS4 Pro's upscale ability is fantastic... I have done side by side comparisons myself and it looks very close. The average user is not going to be able to tell the difference.
