So, my results - on three different size of screens - 60", 50" and 48" LCDs from higher end Sony consumer sets and lower end Seiki set is that all of them are cropped VERY slightly. None show the full 100% raster but ALL show a good deal of the 95%.
93% on ALL of the sets was easily viewable.
Basically, I made a 1920x1080 file in Photoshop. Then made four different colored boxes. 100% of raster was colored red, 95% of raster was blue, 93% of raster was green, 90% was yellow and 80% was cyan.
As I mentioned, I could see a red border (100% to 95%) on all of the sets, fed as HDMI straight from a video card.
Using anything tighter than 90% on these screens would look silly I think. Using 80% as title safe on HD would seem like the designer had screwed up. 90% looks about right for title safe on all of them. I would be completely comfortable with 93% for safe title. I'm shocked at myself for never trying to test this before. I have always used 80% as safe title. Indeed, the Photoshop template for HD is 80% safe title. My eyes have been opened.
This is JUST a test with the four HD consumer sets that I have in my office. All were bought last December. I'd love to see whether others have the same results. Maybe burn a test to bluray and play it at home.
