Sony no longer markets any CRT BVMs, masked or not. But among their latest (NAB 2010 introduction) HD monitors are the 5:3 (15:9) LMD1530W & LMD1751W; the 8:5 (14.4:9) LMD2030W, LMD2050W, LMD2451TD, & PVML3200; and the 4:3 LMD940W. Incidentally, the LMD2451TD offers a full 1920 pixels horizontally but 1200 lines vertically. And the resolution of their brand new, 16:9 PVM-740 is 960 x 540.

In fact, some professional 16:9 HDTV monitors (including some Sony BVMs) use 4:3 tubes covered with 16:9 bezels. You may consider Craig's plan to be the same. There is absolutely nothing lost on the sides.

I'm in complete agreement Bert.
Being a fan of Soccer, a game that can not be fully enjoyed if one
can not see the movement of player "off the ball', I find that
having a full 16:9 image available vastly improves my enjoyment of
the game; 4:3 simply doesn't do the trick!

I am surprised you also misunderstand how common sides works.

The HD version is identical to what you now see from 16:9 HD cameras.

The SD version has the additional throw away areas - top and bottom,
but the 4:3 HD image is resampled to SD resolution.

Think of what a 16:9 HD football broadcast would look like if
letterboxed on an NTSC TV.

Now fill the throw away areas of the NTSC display with what the 4:3
HD camera sees.

Remember that the cameraman is framing everything for the 16:9 safe
image area - i.e. exactly the same framing as would be used with
todays 16:9 HD cameras.

Craig

Of course somebody - definitely NOT Bert - will want the larger 4:3
HD image to be delivered to next generation 4:3 HDTV displays...
