The built-in LCD on the 16702A / 16702B is 800x600. Without the extra memory of Opt 003 installed, the maximum supported resolution on an external monitor is 1280x1024. With Opt 003 installed, the maximum supported resolution on an external monitor is 1600x1200, but at 75Hz, which isn't supported by all monitors. With a 1600x1200 or 1920x1200 monitor which supports 60Hz but not 75Hz, it is possible to use a video scaler to convert between the 16700-series 1600x1200 at 75Hz output to 1600x1200 or 1920x1200 at 60Hz. I tried this today with an Extron DVS 304 DVI video scaler and got decent results with 16700-series 1600x1200 output on a 1920x1200 at 60Hz monitor. I've had mixed results between different Extron video scalers. I couldn't figure out how to configure an Extron DVS 510 to give the same results in this scenario as the DVS 304 DVI.
