Notes

Like the other BA-6 chassis Trinitrons, this TV uses a one-chip design and cannot be modified to accept RGB. However, its component video quality is excellent when the TV is properly set up.

Unlike the larger models, 20" and 13" Wega TVs typically have excellent geometry and linearity, even on side-scrolling 2D games.

Disabling Velocity Modulation

Most of Sony's flat Trinitrons contain a velocity modulation circuit. VM enhances dark outlines on screen, which helps hide composite dot crawl and can make TV and movies look better. However, it ruins pixel art and significantly degrades the appearance of 2D games.

In this model, turning off VM in the user menu does not completely disable it. To address this problem, go to the service menu and set "VMOF" to zero.
