Summary

Standard 20" shadowmask PC monitor rebadged by ViewSonic. Was considered a low-end model at the time by Tom's Hardware due to the low scan range and:

Like the Cornerstone c1035, the ViewSonic G810 uses a Shadow Mask tube. So, this is a low-range 21" monitor with a screen that curves a bit at the edges. The actual diagonal is 20 inches, the pitch 0.25mm over the entire surface and the bandwidth 200 MHz. The maximum horizontal refresh rate is 97 kHz, giving a resolution of 1600 x 1200 at 77 Hz. This is a very low rate - there are good 17" monitors with equal performance at the same resolution. So the G810 is not designed for use in 1600 x 1200, rather, in 1280 x 1024, a resolution where it can reach 85 Hz. The tests showed this was just right for a monitor of this size. In practice, we observed a maximum rate of 77.5 Hz in 1600 x 1200, and 92 Hz in 1280 x 1024.

200Mhz signal bandwidth.

This particular example was made by Panasonic, but we have found several other manufacturers ViewSonic was using for the G810 including Amtran and CTX. You can tell which one it is by the chassis model on the rear sticker.
