Hello, i have a laptop of 6 years ago that can't be connected with the hdmi to my new 4k oled tv; i have read that cromecast ultra can do it but i have a lot of devices connected via wifi on various frequencies and i'd like to know from someone who has it if the ultra version who has the ehternet cable can do the mirroring of the desktop via cable instead of the wifi; and if it can't how much lag it has via wifi?
