Thanks! I had seen some of these videos before but not all of them.

Do you know of a certified 8K DP to HDMI cable? I thought this one would do the job (says 8K) but it doesn't: https://www.amazon.com/dp/B0B5TLQYDG?psc=1&ref=ppx_yo2ov_dt_b_product_details

However the Maxonar brand you recommended does have DP 1.4 to HDMI 2.1, so I'll give that a shot: https://www.amazon.com/gp/product/B09MHB9LT1/ref=ox_sc_act_title_1?smid=A1WU736W1PHVH9&psc=1
