Spectrum HDMI 2.1 48gb/s?!

Hi People Cosmic here,

New to the site, so I apologise if I’m asking a question that has already been answered!

Hopefully it should be a quick one, thanks for the support.

With the new Spectrum 4k 144hz monitor (and other models) in development my PS5 should run a delight! Although the monitor will be more for design/editing than anything, I’m excited to see it run!

I know the monitor has HDMI 2.1 and that would mean 48gb/s right? But it doesn’t say anything on the full specs list about this. It concerns me we may only get 40gb/s compared to the RoG ASUS confirmed 48gb/s that are in development. Could anyone update the full specs for the whole community and new buyers/contributors and let me know here If it’s 48gb/s or not?

TLDR: Is the Spectrum 4k 144hz Monitor HDMI 2.1 48gb/s or not?

I just wrote up a post about this topic and was about to publish before realising someone had asked the same question.

Can you provide the information where you are sourcing the HDMI 2.1 chipset from?

From my limited research it seems only Sony makes 48Gbps HDMI 2.1 chipsets. AVR’s, PS5 & possibly Xbox Series X seems to have sourced their HDMI 2.1 chipset from Panasonic Semiconductor Solutions (since acquired by Nuvoton Technology) which is capable of 40Gbps.

Vizio claimed their 2020 line of Oleds were capable of 48Gbps but it was discovered to only be 40Gbps months after release so I’m unsure where they sourced their chipset from.
