Magewell already offers a capture card that is capable of grabbing 4K resolution footage at 60 frames per second over an HDMI 2.0 input interface. However, its new Pro Capture HDMI 4K Plus LT ups the ante with a loop-through HDMI connection to allow source signals to be sent simultaneously to additional displays or equipment without needing an external HDMI splitter.

"The new loop-through capabilities deliver these benefits for any type of user but will be particularly popular with price-sensitive gamers, who can now record and livestream their 4K gaming sessions at 60 fps from the HDMI output of their game console without requiring a splitter to also connect their monitor," Magewell says.
