Here are some settings that I created for my older 428XG for the Astro B.yond Box.

These settings are quite bright and can be used for all the HD channels. However, for the sports channels some might prefer a slightly brighter image. When I get the time I will create one for that. These settings were created using a pattern generator at 1080i. Since Astro does not broadcast any test signals, we have to hope that they adhere to the HD standards. The PACE STB uses Broadcom chipset that shd handle SD to HD colour space conversion correctly. However, YMMV with the various programming since they source the channels from various countries.

I have not tested the accuracy of them with Astro b.yond per se as my Astro is currently hooked up to my other set but they shd be pretty good.

Notes to keep in mind.

I will not be responsible if any problems arise with anyone using these settings. Use them if u want, else don't use them. They do not sustitute a proper calibration as each set is unique. My set has already 2500hrs on it so its pretty much broken in. The settings give a bright image (~40ftL) that shd be more than bright enuf. I doubt they can be used for the 508XG but it does not hurt trying. Also, if your set is less than 200hrs I woud suggest toning down the contrast to below 30. This reduces the chances of burn in from the bright Astro logos.  If I use the ISF modes, the greyscale is flatter, but I can only do it on site.

Anyway enjoy. I also attach the calibration reports for these settings based on my set. BTW, I always fill the screen when I watch Astro, so under Options I use Auto Wide Zoom.
