I didn't think it required one. Thought you might have made the effort to go learn the differences.

The "resolution settings" in that Xbox video is the settings that influence the external resolution, which is what the scaler will work to upscale or downscale the game to.

Just because you set that at a specific resolution does not mean that the games internal rendered resolution actually changes.

Never claimed the internal renderer would change the resolution. That's never what I was going for. I was going against your bold claim, that "the Xbox upscales and downscales to match your display." That is simply false, because the xbox doesn't know the display. If I would attach a 4k display on the xbox it won't upscale the image to 4k. The TV would do the work, because the max resolution output is 1080p on the x360. Thus your statement is simply wrong in that regard. 

Faux-K lol.

GT Sport is 1800p.

Wipeout Omega is Native 4k with motion blur turned off, with it turned on it's checkerboard.

This is what logical people expected all along, and is what MS lead us to believe. Their own games will strive for native 4k, third parties can do what they want. The only absolute is that it will hit native 4k more consistently than the Pro. And most importantly is a massive upgrade over the Xbone :)

Actually. The Xbox does detect your display and will set a resolution to match. It does actually have a degree of display discovery.
You are also allowed to change it independently from that however.

If you were to plug your Xbox into a 720P display, it will output at 720P. If a game is rendering at say... 1080P then the Xbox will downscale the game to match your display's 720P resolution.

If you were to plug your Xbox into a 480P display the Xbox will detect that display and try and match it. The games themselves will still render at whatever the developer has set. And there is a reason for that. It's called consistency. Everyone gets the same experience regardless of what you plug into the box.

On the Xbox One S/X it will upscale to 4k.
The Xbox 360 will not upscale to 4k because the Xbox 360 is simply archaic, the scaler was built before the 4k standard was ratified so it has no hardware support for that standard.
Not to mention it doesn't even have HDMI 1.4 or newer anyway.

I found it myself. This feature is called EDID.

That's the one!

So they lied about 'true' 4k. Why microsoft? Just be honest to your userbase!

Seriously, if you want 4K/60fps you should not be looking at consoles to begin with.
