1) update firmware
The first thing you should do after you unboxed your Samsung PS50A550, is update the firmware! This will fix several key issues with this set. Including fixes for focus / blur issues, judder at 1080p24. The latest firmware also reduces issues with false contouring on human flesh(but doesn’t complete fix it). You can download the latest firmware at the samsung website , and an easy to follow manual.
2) connecting the PS50A550 / PN50A550
Connecting the set is quite easy. Just a few reminders
only scart1 is RGB. If you’re still using Scart cables, buy a fully wired one, and connect it to scart1.
when using a DVI=>hdmi cable you must use HDMI2
3) how to enter the PS50A550 service menu :
When off, press info, menu, mute and power.
To get out again you’ll have to turn the tv off and then on.
ALL SETTINGS WILL BE LOST WHEN YOU ENTER THE SERVICE MENU

What is the native resolution for your TV from the VGA in (i.e. if you plug a pc/laptop in, do you get 1920 x 1080 – using the VGA connector specifically)?

I’m using aX360 on the VGA connector. It feeds the TV 1920 x 1080 and the tv has no problems accepting the 1920×1080 signal.
