just one comment to that. It is no problem to fit PFD, ND and clocks on a 19 inch widescreen.
However, if you have a full scale setup a 19 inch widescreen will be too small. even a 20 inch widescreen is too small.
The 19 inch widescreen is exactly perfect for just the PFD and ND is you work true scale.
See the pictures below.
Its possible to use a bigger widescreen (23 inch ?) to display the clocks also, but problem here will be that they will be higher than the glareshield.
I will try to use a 5 inch or smaller (4 inch) tft for the clocks alone.
Below pictures of the Acer 19 inch widescreen TFT. My mip is exact scale (1:1) and it fits perfectly for PFD and ND.
