| == RGB Mod Information ==
| |
| RGB modification information for this specific model is limited. The AV-20D303 may share similarities with other JVC 20-inch models like the AV-20D202, which uses the same board as the JVC AV-27230. However, JVC sets often digitally disable unused RGB signals via the Jungle IC's RGB SEL register, making RGB modification complex and potentially requiring microprocessor intervention. Since this model already includes high-quality component video inputs, an RGB mod may not provide significant picture quality improvements.
