HDMI switch 1440p 144Hz

Those claims supporting "up to 4K@60Hz" are not "true" HDMI 2.0 switches.

4K@60Hz requires merely 12.54 Gbit/s which will not saturate the full bandwidth of HDMI 2.0 at 14.4 Gbit/s. 1440p@144Hz, however, requires a bandwidth of 14.08 Gbit/s, which is nearly the full capacity.

The root cause is the IC within the switches. They usually use the cheap and mass-available Texas Instrument HD3SS215 series (and its derivatives). They only partially supports HDMI 2.0 standard, since they are designed to handle 60 Hz signal at max, not 144 Hz.

A proper high-end HDMI 2.0 switch is needed for 1440p@144Hz switching. I remember seeing one at a website with a hefty price tag of near a thousand USD.

Alternatively you can try getting a validated DisplayPort 1.2 switch and use an adapter for HDMI output. Level1Tech has one that is capable of handling 1440p@144Hz.

Hello guys. Do you guys know if there is an HDMI switch that is capable of handling 1440p 144Hz? 

 

Thanks for the answers already :)

Full 1440p@144Hz support is possible over HDMI 2.0(b).

Any HDMI switch supporting HDMI 2.0 and above should do the trick.

Someone I know got a HDMI 2.0 switch but that one does not work for some weird reason, can you maybe explain why. The switch supports 4k 60Hz, so you would assume that I would also support 1440p 144Hz. He got this one: https://www.amazon.com/EZCOO-HDMI-2-0-Matrix-60Hz/dp/B078YS79HZ

I just ordered the Amazon - ATEN VS82H 2 Port True 4K HDMI Splitter from another website for under $75... hoping it works as I have been struggling to find a way to have 2k (1440P) on my monitor and stream to my elgato HD60 S+ (limited to 1080P). Right now I have to either stream to 4k on my monitor that makes text unreadable or stream 1080P which produces a tiny screen inside my screen. If this works I will be a little upset that I spent more for the HD60 S+ over the HD60 S in order to have the extra output, but a small price to finally be done messing with this setup.
