CRT:Disabling Velocity Scan Modulation

Velocity Scan Modulation (VSM) is a feature for various flatscreen CRT televisions across different brands. It attempts to make the image appear artificially sharper, but can cause the image to look worse, especially with pixel art and text. Generally, it's only present in 27" and larger sets.

Disabling VSM

Sony

Smaller sets (20" and smaller) and the S series do not have VSM. It appears that turning off the Color Killer feature (KOFF) also turns off VSM.

BA-5D chassis (e.g. KV-36FV310): Turn off "ClearEdge VM" in the user menu. Alternatively, you can change "KOFF" to 1 in the service menu, save it, and turn your set off and back on.
BA-4D chassis (e.g. KV-27V42, KV-27V66): Change "KOFF" to 1 in the service menu, save it, and turn your set off and back on. Alternatively, you can unplug the cable connected to CN942 on the neckboard.
BG-3S chassis: Change "VMC" to 0 in the service menu, save it, and turn your set off and back on.

Toshiba / JVC / Orion

20" and larger sets likely have VSM and must be disabled by unplugging the three-pin cable on the back of the neckboard. A video showing the correct cable can be found on CRT Autist's channel.
