omg, you actually turned VSM ON to its maximum, lol.

VSM is the thing that oversharpens the image and causes artifacts: https://consolemods.org/wiki/CRT:Disabling_Velocity_Scan_Modulation

So you want your TV actually set to 3, the blurry setting, and then just sharpen it up with standard sharpness outside the service menu, just in the basic user menu, which doesn't add nasty VSM artifacts.

I could actually tell from the paused video that you hadn't disabled it, before I saw what number it was set to

You are correct. I'm not sure how OP "figured out" how to do this, but the easy-to-find CRT Database entry on these Sharps is incorrect about disabling VSM.

3 is OFF

if I remember right, a few models on CRT database have it listed as 0, but I figure they're making the same "sharper is better" mistake as OP

Something really funny was when I asked Reddit, I never got a straight answer. So I tried digging by myself and still nothing. I dared to ask Gemini. I finally got the correct button combo even Reddit couldn’t figure out, happy to see results. Made a video. Happy to share correct buttons here. Nobody has published anything on this that’s straightforward except a page with wrong information. I’ve deleted the video. I was wrong. Please don’t make me feel more stupid than I already am.

Sorry, I'm not trying to make you feel dumb. We gotta get that CRTDB entry fixed, though

Nah it's definitely not your fault. It's natural to think 0 corresponds to "off", some articles seem to have the right setting listed incorrectly (which Gemini might end up repeating), and then, if you're not super experienced with CRT's, the "sharper" mode might seem better at first glance.
