Hello,
New to the site.
Is it true that if you watch a Stadard (4:3)show or movie on a WideScreen (16:9). The left & right side block can cause a problem for the Projection Lens?? Meaning you should only watch WideScreen Films, show, etc. on a WideScreen Projection TV ??NO IDEA ?? HELP
Thanks in advance !!!
It also depends upon the specific projector. Some are equipped to handle the differential scanning that the John described by using a gray bar system instead of black to keep the phosphor burn relatively even. By the way, it isn't just needing to watch widescreen since some widescreen will cover only certain parts of the screen after all (e.g., 1.78:1 covers all of a widescreen but 2:35:1 doesn't for the standard widescreen 16:9 set). For a 4:3 screen, you need to vary the type of widescreen format as well just to be on the safe side (probably will happen naturally if you view a wide variety of movies).
The crucial bit for the projector lens is in the first 100 or so hours of break in. I was not careful myself and used 4:3 too much resulting in a couple of brighter strips either side in widescreen mode. Since then I've projected as much as possible in 16:9 even if the original is 4:3. It results in some chopped off heads and diminution of brightness, particularly in NTSC laserdiscs, but is generally bearable. The bright strips are slowly diminishing their relative brightness.So, you can use the projector for all formats, but the initial break in period is quite critical.
Peace at AA
John
