Initial impressions.
Thank goodness that I read the cnet review first, hooked up the console and it had no video output at all, syncing issue with my 4k set. Very strange, it should have displayed regardless if resolution. Hooked it up to another TV and downloaded the two day one updates via wifi, brought the console back in my room and working fine. Initially 4k upscaling was disabled. You MUST enable HDR on your 4k display to enable upscaling.
I hear the new controller feels like cheap plastic crap and the d-pad feels worse, so used my old xbox one controller. I'll probably sell the new Bluetooth controller as new without taking it out of the baggie after I read more reviews and decide if it's worth keeping.
Once all was said and done threw in DOA5 and plugged in my joystick. I will say that the 4k scaling looks great, and graphics aside, I'd cringe looking at an unscaled 1080p PS4 game after playing on the One S. For this same reason I always bought multiplat titles on 360 over PS3 for the 1080p upscaling. I have an 8core Samsung JS9000, and frankly the internal scaling isn't that amazing. I'd say if you own a 4k display and there's at least some games you'd play that are available, I'll give my seal of approval on this console.
As for the UltraHD Blu-Ray player, I'll pick up a title later today to check it out. For gearheads, this may NOT be the UHD player for you. Why you ask? Apparently the One S doesn't support Dolby Atmos. I don't have an audio setup at all right now, so I don't care. There's also the possibility that support could be easily added in the future via firmware I believe.
That about wraps it up. It does exactly what I wanted it to do. It upscales games wonderfully, has a built in UHD player and also upscales your TV channels should you wish to hook up your cable or satellite box (why not?).
More info later, I'm going back to enjoy my new toy.
