Summary

Mid-range 27" model from Sony's flat screen Wega line. Picture quality is very sharp, as the tube has a finer pitch than earlier curved Trinitrons of the same size and it includes component video inputs. However, due to the flat tube design these TVs often need adjustments to fix geometry and convergence problems that have developed over the years.

Notes

Composite 240p Performance

by Eli Krause

For composite decoding this set uses a Toshiba TC90A49P, a 3-line digital comb filter. Depending on the console/revision, dot artifacting ranges from slight to severe, and blending effects may be broken. If the set has a component YPbPr input on, then using a good external notch filter to decode composite instead (such as the one in a RetroTink) and sending that to the component input would blend all dithering patterns and remove nearly all dot artifacts (full guide here). A recommended no lag HDMI to component converter is available here.
