I'm looking to run an elgato or some sort of gaming capture device, but I've heard they can cause input lag. I have a extremely low lag monitor and don't want to add any. I'm looking for a splitter to run my hdmi xbox output wire into, and then one hdmi will go into my monitor and one will go into the elgato. I've heard powered ones cause little to none, but have found no proof. Can anyone suggest one?
