AA Chipset and Widescreen Displays

[ACE]

Has anyone ever tried getting widescreen workbench using AGA?

I ask because I have a little project in the pipeline to make a CD32 laptop from an old PC Laptop.  Unfortuanetly getting the LCD display to work seems very unlikely (see previous posts!).  So I've been looking at 'cheapish' LCD diplays that could be used via RGB/Composite connection.  The best choices so far are a PSOne 5inch LCD display (which I think may be a bit small, but only £100 or so even cheaper on ebay!) a 7inch widescreen displays for £140 (which isn't a lot larger but would look pretty cool I think).  I know that I could buy a cheap 15 inch LCD display for £150-170, so don't nobody tell me the obvious.

Anyway anyone had a go with W/S Workbench?

OK, seems good.  The problem being I'm trying to use a LCD display, so I would like to run at native resolution WITHOUT stretching, ie get a clear as possible picture, important when you only have 7'' to play with  ;-) ...

The cheap one has a 480 by 234 resolution (now I know why it's cheap (still approx. 2800 dpi at my calc)).  So now the question is can I run a dispaly like that.  Seems a bit too high for standard overscan.  What about "MonEd"?  I have never used that could that produce a 15.6kHz output with 480 pixels wide, or am I starting to break the laws of physics?  Basically how much of these screens could I fill, or should I just stay with the cheaper and smaller 5 incher standerd PSone display!!!
