Why is my 1440p monitor outputting 4K with consoles?

I don't understand what resolution im playing at with my PS4 pro. From what i've read the PS4 pro is 1080p or 4K and 1440p is not supported, but.. according to my Pro its outputting 3840x2160p HDC P2.2?

I can't enable super sampling because it thinks its higher than 2k. The image quality is great however if i switch to 1080p or use a older Hdmi cable to enable super sampling you can tell the image quality is worse.

Any ideas what's going on here?

Happened to me on the X, it accepts a 4K signal, so I'll assume upscaled 4K is occurring.

Your Pro probably autodetects it as a 4K screen. But it won't be 4K. Your monitor can't do higher than its supported resolution. If your Pro is sending a 4K signal, your monitor will sample down to 1440p - aka, you are doing super sampling. On the other hand, if the Pro is really rendering at a lower res and upscaling to 4K (as is almost always true), then the native res may in fact be roughly 1440p, scaled up, and then your monitor will scale it back down. No free lunch - it's 1440p no matter what you do, but the Pro may render at some other res

Hi...I know that PS4 pro doesn't support 1440p but i was wondering if anyone knows away i could get it to output 4k and downscale it to 1440p or upscale 1080p to 1440p. I looked into the Mcable and it doesn't support 1440p or doesn't say it does atleast.

Seems im one the lucky ones. From what i have read most people with 1440p monitors can only get 1080p. Other than that you will get a horrible upscale/downscale that makes things blurry looking. I actually had a Acer 4k monitor which would only output 1080p with the pro because they put old HDMI ports in it. You need high speed 2.0 HDMI for 4k etc, if you haven't got that your screwed.
