Thanks for looking it up for me (especially since I'm dumb with this stuff).
So just to be clear, all the 4k ports will output 1080p at 120hz? Or only on the ONE HDMI 2 + port, and the other ones are 60 hz?
Right now I have my PS4 hooked up to the best port (the HDMI 2.1 one or whatever). Then I have my Xbox One, my Wii U and my Apple TV on the other 4k @ 30 HZ ports (HDMI 1.1)
The Wii U and Xbox One are the only ones i care about. I know none of them output at 4k, and all of them upscale the 1080p to 4k (which looks amazing). Was just curious about the refresh rate and how that works for when it's 1080p output on them. Sorry for asking so many questions.
If the other ports don't do 120hz at 1080p, then maybe I should get like a HDMI switch to plug into that HDMI 2.1 port. If such a thing exists, and just have all the other ones run off that one. Either way, I can't stress how much I love this TV. I know Vizio isn't the best brand. And I know it has issues. But gah damn, 4k Upscale + this TVs picture in general is so mind blowingly beautiful. And I sit close to the TV in my room, so 50 inch is perfect.
Forza Horizon 2 on this is wow.
The best way to think about what ports do what, it is best to ignore the TV's final post processing hz number.
So for instance, look instead at what the source output is. For every device you have there, 1080p @ 60hz is going to be there highest output. So realistically, at this point, it makes no difference which port you use.
The only device that could potentially make any difference is a PC. Obviously it depends on the power of your PC's GPU, but theorhetically, if your PC was powerful enough you can output at 120hz (120fps) then you could;
You could play a game in 1080p@60hz (ie. 60fps) on any of the four HDMI 1.4 inputs, same as a console, bluray player etc
Or any game in 1080p@120hz (ie 120fps) but only on the HDMI 2 port. This is something usually only available on PC monitors
Or if you want 4k at 30fps the HDMI 1.4 ports will do
Or if you want 4k at 60fps you must use HDMI 2 port.
Is it worth using a splitter to send all information via HDMI port 2? No.
The through put of each device is limited by;
The output device (Xbox, PS4, Bluray player etc)
The HDMI cable
Or if you added, the HDMI splitter
It will never be higher than the lowest common denominator. If the output device tries to send a signal higher than the capabilities of the HDMI cable or what the splitter is able to send, it just wont send anything.
If the HDMI and splitter are capable of sending more than what the output device is cable of, they just wont be using their full capabilities as you will be limited to what the output device is sending. So there wont be any difference by the time it gets to the tv, it'll still be exactly what the output device sent with no improvements.
Not trying to confuse you but there is only one instance that would make any difference. The only variance to this is say, a HDMI splitter that also acted as an upscaler to 4k @ 60hz (this could be a HDMI upscaler / splitter like device or maybe a home theatre receiver that does the same thing). Otherwise if all it is doing is passing througn the signal with no post processing it doesnt matter. Either way we are talking about devices worth hundreds, not just a standard splitter that simply switches signal paths.
The TV's ability to output any source at 120hz is entirely inconsequential from the point of view of the output source and which port you use. The 120hz (its actually 240hz on this tv) is more to do with frame interpolation, strobing etc that is used to minimise judder in video output, its not actually related to how many frames the source device is outputting, therefor for the purpose of worrying about which HDMI port you use, you can entirely ignore that spec. So the simple answer to your question about port use and 120hz output from the TV side of things, you can always get 120hz from ANY port you use. Its being done in the TVs software / processor. It is only ever an issue from the output source.
Its confusing, I hope I cleared it up a little.
Just think, the HDMI ports and the signal speed (hz/fps) is only relevent when considering the output devices and what they output, not what the TV is outputting.
