Hey all,

I have a blueray drive that I patched a long while ago and I cannot remember if it will read 4k discs or not after I've patched it. Is there any way I can find out? This is what the drive shows up as in MakeMKV below. I don't have any 4k discs to try and was going to buy one but didn't want to buy it if this drive wouldn't work. Thank you!
