Display size / Quality question

[illusive_21]

Ok I run at 1400x1050 resolution, not sure if thats odd or abnormal selection. It's the default option for my monitor and works well for me. I'm very new to streaming, so i'm looking for just some general help on how to improve quality of my streams. Below is link to my VoD tibits, trying to setup good resolution. I have tried both 16:9 and 4:3 , nothing really giving me near quality I feel I can push. I have very good PC with Nvidia 260GTX card. Anything anyone can advise to adjust in using Livestream Procaster program to help my quality of my stream?

Current settings are:
Encoder: H.264
Output: 640 X 360
Aspect Ratio: 16:9 (Lock Ratio)
Target Framerate: 22 FPS
Target Bitrate: 500 Kbps
Keyframe Intervals: 2
