Talk about thread resurrection! Just thought I'd update 3yrs after getting the set and offering a few tips: working perfectly and now working even better. I'm using the 60PZ550 as a presentation monitor from my PC via HDMI (on both Windoze 7P and Kubuntu Linux, using an Nvidia GTX660 video card with dual DVI+HDMI+DP). I had an issue with overscan (where the picture stretches a bit to where I had trouble accessing top line menus). After researching a bit, I found that this set has Just Scan
(ironically, from my other Plasma - Samsung). This effectively disables the overscan and sets things just right. I did not notice any difference during normal U-Verse HD watching; however, for a PC - awesome!
So - if using a PC and you're having a menu access issue or cut-offs: (On your remote) - Hit the Ratio button-->Enter-->(select) Just Scan. --OR-- Home-->Picture-->Aspect Ratio-->(select) Just scan. -- OR if using THX -- Home-->Picture-->Picture Mode-->THX -or- THX Bright Room
(this automatically sets the AR to Just Scan).
From LG documentation: "Just Scan: Normally the edges of video signals are cropped 1-2%. Just Scan turns off this cropping and shows the complete video. Notes: If there is noise on the edges of the original signal, it will be visible when Just Scan is activated. Just Scan operates only in DTV/Cable DTV/Component / HDMI - DTV/ DVI - DTV (720p/1080i/1080p) input source."
I don't see me upgrading to 4K anytime soon with zero providers (except Netflix) in my area offer 4K content. Maybe I'll come back in another 3yrs.
