Users experiencing issues with certain videos not playing on Dell or HP laptops running recent CPUs might not realize that both companies have recently disabled H.265 video encoding and decoding. The decision, likely aimed at reducing licensing costs, could complicate video streaming, editing, and other related tasks.
Users on various forums have been troubleshooting video playback errors on newer Dell and HP laptops over the past few weeks. While the specific issues vary, recent software decisions by both OEMs appear to be the root cause in all cases.
Complaints have come from users of models including the Dell Pro 16 Plus, Dell Pro 14, Latitude 7350, HP ProBook 460 G11, ProBook 465 G11, EliteBook 665 G11, and other similar business laptops. The affected devices generally feature Intel Core Ultra 100V and 200V CPUs.
