Summary

One of Sony's last series of curved Trinitrons, sold from 1997-1998. It is very similar to the KV27S40 and uses the same tube and chassis design. The V series TVs were sold as premium models, and include features like side mounted speakers, extra A/V inputs, A/V monitor output, and velocity modulation.

Notes

A higher priced version of this TV, the KV-27V65, was also produced. This model featured higher wattage speakers and a Picture-in-Picture feature.

This TV, along with other higher end Trinitron models, includes a Velocity Modulation feature. While this can help improve picture quality and reduce composite artifacts with video content, it fares poorly with pixel art and can have a detrimental effect on game graphics. It can also be disabled by disconnecting a connector on the neck board. This is a 4-pin connector with a short cable that runs to a coil on the neck of the tube.

Composite 240p Performance

by Eli Krause

For composite decoding this set uses the Sony CXD2073S, a 2-line digital comb filter used in many models from their 1997-1999 lines. As with all 2-line comb filters, the amount of dot artifacting added to 240p content is severe. If the set has an AA-2D chassis, then the set's own internal notch filter can be enabled in the service menu - NOTC 1, which will avoid the horizontal dot artifacts caused by the comb. If the set has a BA-4D chassis then there is no service menu option to enable the notch. But if the set has an s-video input (or if it has been modded for component input, or if one does not want to toggle a value in the service menu when switching to and from using composite), then using a good external notch filter to decode composite instead, and sending that to the set would properly blend all dithering patterns and avoid nearly all dot artifacts.
