Thanks to all who posted on this thread on the screen replacement.

I had purchased my screen from http://www.Earthlcd.com and the screen that was sent to me was a UG24U01WGHT3A screen from Samsung (39.00 + 5.00 frt). Circuit board quality was much better than the original on my Pronto screen:

L303517-1 PCB576

The clarity is much sharper and seems brighter. The earlier threads on installation were a big help. Thanks again.
