Frequently Asked Questions - ST122HD20S StarTech.com
What is the maximum resolution supported by the ST122HD20S?
The ST122HD20S supports resolutions up to 3840x2160 @ 60Hz (also known as 4K UHD) with 4:4:4 chroma subsampling, ensuring crisp text and vivid graphics.
Can I use this splitter to send the same image to two 4K monitors?
Yes, the splitter duplicates the single HDMI input to two identical outputs. Both monitors must support the same resolution; the splitter does not modify the signal and will output the native source resolution.
Does the splitter support HDCP 2.2?
Yes, it is fully compliant with HDCP 2.2, allowing you to stream protected content from services like Netflix or Amazon Prime without issues.
Do I need a power adapter?

Can the splitter downscale 4K to 1080p?
