Is my device compatible with 4K60Hz through the Viper?

These are the following Apple devices that support dual 4K60Hz with the Viper:

• MacBook Pro (15-inch, 2017 and later)
• MacBook Pro (16-inch, 2019 and later)
• iMac (Retina 5K, 27-inch, 2017 and later)
• iMac (Retina 4K, 21.5-inch, 2017 and later)
• iMac Pro (2018)

These are the following Apple devices that support 4K60Hz through either of the HDMI ports (individually)

• iPad Pro 11-inch
• iPad Pro 12.9-inch (3rd & 4th Generation)

For Windows devices or devices that use Chrome OS or Linux, you would need to check if your computer is DisplayPort 1.4 compatible through the USB-C port. Otherwise, you could only use the direct USB-C to HDMI line on the Viper to get 4K60Hz.
