What the heck, my BIOS screen is 1080p now

Yesterday I built a new gaming PC inside a compact chassis and using one of Asus' latest tiny motherboards, the ROG Strix X870-I Gaming WiFi. To my surprise, this cutesy PC booted first time. To my even greater surprise, the BIOS erupted onto my screen with a gloriously crisp finish.

"Wow", I thought to myself as I glared at the sharp edges that replace the fuzzy 768p interface of decades gone, "they finally did it."

I then set about hurriedly finding out when this change happened.
