Someone asked a question about 120FPS, and next gen consoles.  But we know how that goes.  Not making sure your output monitor can display 120FPS, leads the ill-informed to think "the human eye can't tell the difference."  I feel like having a totally different output connection reserved for refreshrates above 60 would help eliminate misunderstandings.

Most TVs already don't support 120 FPS.  But I don't think there are any monitors out there with display port, that don't support 120 FPS.  If a TV has display port, then maybe it supports 120 FPS.  I'd imagine that if a TV has display port, it also can support 120 FPS.

Or, maybe the console itself can detect rather or not the TV supports the refreshrate, so having display port wouldn't be outright required anyway?

This 120 won't be the standard. maybe one or other game which focus on VR will have this. Plus remaster of old games could reach that.

What does 120fps being standardized or not have to do with public per perception of 120FPS, for the games that potentially will support it, and not be VR?  A VR game running 120 fps requires more console resources than a regular game running 120fps, so that doesn't make sense.

Don't expect such games to have top tier visual levels, focus will be VR gimmicks, not AAA visual experience.

You know that most TVs in the next years will come with HDMI2.1 ports, don't you?

I'll be happy if next gen consoles have locked 60 fps. I don't expect anything beyond that.

The consoles already can detect that!

I can already choose between 1440p at 120 Hz and 4K at 60 Hz on my Xbox One X, since it detects support for both modes of my TV. It also already supports variable refresh rates (VRR) and low latency modes:

good luck finding an 8k tv that supports 120hz

You are joking, right? There are thousands of 60-Hz-monitors out there with a display port.

F.E.: here are over 800 of them currently available on the market:

A 120hz output refresh rate helps reducing lag even in 30 fps games and 60 fps games.

The refresh rate of a monitor has an impact on input lag. A 60Hz display, for example, will never have a visible input lag below 16.67ms, because that’s the amount of time which passes from one refresh to the next. A 120Hz display halves that time to 8.33ms... and you don't have to render 120 fps to benefit from that smaller lag.

With VRR there is even less input lag, since the rendered frames are sent instantly to the display when they are finished, not 16 or 8 ms later. If done properly, games with unlocked framerate can stay smooth if they stay above ~40 fps.
