No 4k120Hz. bummer. To be fair, 4k120hz is not a primary market pull.
It's for people to play on their living room TV. Most of those don't do 120 Hz.
I do 120 hz on my TV. With PS5 and Xbox I think market for it is bigger than you would think for 120 hz TVs among gamers who picked up new TVs when they got their new console.
It's been a long time since I looked at consoles, how many games will render at 120 fps? I thought developers would try to find a balance between fps and graphical fidelity. Do games have uncapped fps now?
Here's a list here. https://www.psu.com/news/all-ps5-games-that-support-120-fps-the-smoothest-games-on-playstation-5/
Right, like I said, 4k120hz is a very limited market. However, for those of us with living room OLEDs, 4k120hz would be very much appreciated. The couch gaming experience on a 77 inch 4k120hz oled is pretty wicked.
They’re becoming more common though. The Sony oled I just got does 4k120. I’m bummed it doesn’t have hdmi 2.1 though. VRR would have been nice but maybe the hardware is powerful enough it won’t need it.
It has DisplayPort 1.4 which supports 4K@120hz
Fair enough. The displayport has limited use though, given how there aren't many (any?) large 4k120hz televisions with displayport. And let me be clear, that's no dig against displayport (which is the better standard). As far as I know, certain shady license deals keep hdmi artificially ubiquitous on televisions.
That same shadiness is why AMD GPUs can't directly support HDMI 2.1 on Linux. But there are workarounds like DP to HDMI converters or using 4:2:0 which is tolerable for non-HDR gaming at least (not so much general PC use).
Yeh this will make it a tough choice for me. Have an OLED TV and playing something like Hades 2 in 4K120 would be really nice. Maybe a USBC hub/adapter could do the trick but that’s kinda weird and an extra cost. Definitely dampened my hype for it sadly.
I mean if you're playing older stuff it will output 4k 240. You can probably run Crysis at 4k 240 on that thing.
Eh, that's not really how it works. It all comes down to the HDMI standard. The HDMI 2.0 used by the steam box has a max officially supported output of 4k60hz. You need HDMI 2.1 to get 4k 120hz - regardless of the capability of your machine.
I'm fairly certain that there is an issue with AMD and HDMI licensing that is a barrier here
Ah, I was looking at the DP specs not the HDMI.
