CRTs used to really suck. Especially early color NTSC units. It’s probably not doing so hot after 40+ years. But even 80s color TVs were bad. Add only supporting RF and not even composite/RGB and they looked like butts. Then pile on all the conversions needed to get from HDMI to RF and yeah…

We mostly just remember the end of the line CRTs when they’d largely perfected them.
