I'm not so sure TV's have routinely been ahead of computer displays. They progressed from regional Standard def analog systems with a maximum broadcast quality of 720x480 or 720x576 interlaced, and in practice often much less, VHS quality could be half or a quarter of that, 350x240ish... TV's weren't showing even 480p until digital/DVD. Small niches for analog HD TV in Japan and Laserdisc nerds could do better, but virtually no one had that. The first five figure plasmas were 480p widescreen affairs (850x480), and the first gen of HDTV was only 1280x720. 1080P sets only really hit in the late 2000's... I'd had at least a 1024x768 or better display since the mid-90's, and 2560x1440p/2560x1600p for over a decade. My computer displays didn't fall behind TV tech until 4K became popular...
