It handles the upscaling itself, instead of the TV. Which should give it an advantage in certain areas such as display latency. It really depends on your TV how much an advantage it's going to be. Some tv's are rubbish at upscaling themselves so teh XBO S having it's own will be a good benefit, but other tv's are really good at upscaling themselves too.

Yep it depends on the tv. With Alan Wake I got better image quality on my projector by letting the projector upscale 720p to 1080p (setting the 360 to 720p output) instead of letting the 360 handle the full upscale. If you have a high end 4K tv you might get a more pleasing image just leaving it in 1080p.
It depends how the upscaler is going to work. If it's a simple quadrupling of pixels of the 1080p buffer to reduce lag and unnecessary switching of display modes than the tv can likely improve iq at the cost of added latency.

To be fair, the Xbox 360's scaler can't hold a candle to modern scalers that use more complex algorithms. But your point is valid.

I don't really understand this. 4K TVs already come with upscaling.

Is the slim going to do something the TV can't do?


1) It will help eliminate input lag by removing the processing burden on the TV.

2) Developers can use the scaler to do simple things like image sharpening, blurring etc'.

3) It's using more complex hardware with a more complex algorithm to produce a better scaled image.

At this point, if I were to buy one, it would be to have a cheap UHDBR player.

But I'm getting a PS4K, anyway, so I'm not sure I'll need it.

Actually thinking a bit more about it, this could be brilliant if handled right.
It can make snap mode much more desirable. Instead of shrinking the tv picture down to 480x272, on a 4K screen it would only need to go down to 960x544, retaining half of the 1080p tv stream instead of a quarter. The main game image then takes up 2880x1620. Maybe a future update can let you adjust the size of snap mode and get the option of 1440p next to 720p or even two full 1080p images. The best feature of my old 34" HD ready CRT tv was the ability to put ps2 and SD tv image next to each other with hardly any image quality loss on either.

1) And the scaler in the SoC works in zero time ????

3) How do you know? Do you really think a high-end scaler chip cannot be better than something crammed into a SoC ????

Glad I pre-ordered! Now I need a 4K tv

It seems like a very nice media and gaming box. Even more so than the original XB1.

1) Of course not, but it's running on a fixed function pipeline, not a shared processor in a TV that has to deal with other tasks.

3) Because I understand hardware. TV's especially low-end and mid-range TV's tend to make concessions. There are plenty of TV reviews around the web that back this up, if TV's were the best at scaling, consoles and PC's wouldn't need their own scalers would they? Exactly.

Hey you didn't give me your opinion on the gain this internal upscaler (because if PS4 Slim or Neo have one it'll probably be similar) against Sony XBR-65X855C

The Sony XBR-65X855C is trending towards higher part of the mid-range 4k TV market (As it's an 8xx model, still better than a ton of high-end 1080P panels though and a league ahead of cheap corner-cut low-end 4k panels.) 4k TV, Sony do typically have some of the best scalers in the TV business anyway.

The PS4 Slim and Neo will likely use an AMD scaler, which would still likely have the edge and should reduce input lag, either way, you will still have great upscaling results either way.

Um... You know my TV already upscales on its own right? That's just something TVs do these days. Saying "our console will support upscaling" is like saying "our console supports the use of electricity!"
