Welcome to the forum.

Actually, tomorrow we're going to launch a webinar on how to adjust settings and how to help set your television up.

As well, there is an HDTV Picture Settings forum broken down by model. You can find it for the LN52A950 here:

If your television isn't listed, you can start a thread so that other owners can jump in and share their best settings.

If your television isn't experiencing any problems, I wouldn't necessarily suggest updating the firmware.

Hope that helps!
