If it's the same 21" Sun that I had back in the days the native resolution is indeed 1600x1200. Sony Triniton tube, those screen were fantastic.

Mine could even do 800x600 at 160Hz, my first experience with high refresh rates. Felt like I could grab the windows and pull them out of the screen.

Given that it's a CRT wouldn't it be max resolution instead of native? The 800x600@160Hz would also be driven natively I assume.
