Amigas and Widescreen 16:9 monitors for Workbench & rendering?
« on: December 03, 2009, 01:50:25 AM »
I have a couple of questions...both of which are sort of related and deal with using Amigas with widescreen (16:9) displays.

Is there any way to get an Amiga to PROPERLY display at 16:9 ratio...I don't mean merely stretching the image, but rather creating a proper custom screenmode that is truely 16:9 rather than 4:3 so that Workbench actually has more real-estate on either side?

This leads into my other question.  I am learning to use Lightwave and Aladdin4d (rendering software) and want to produce small renders and animations that are truely 16:9 in ratio.  

Now...I know Aladdin4d will render to any Amiga screenmode you have installed....so if you had a true custom 16:9 screenmode, then you should be able to render true 16:9 animations for YouTube or DVD.

I want to avoid either stretching the image out from 4:3 to 16:9, or taking a 4:3 animation and cropping it to 16:9.  The latter would work, but it's a waste of rendering time and throws away valuable lines or horizontal resolution.

So...what are the solutions for 16:9 video on the classic Amiga?

I am sorry, this is not my really my area of expertise, but i can tell you i believe that there is an experimental driver for widescreens on the HighGFX package you can find in Aminet.

My 2 cents

Not sure about native screenmodes but with a graphics card you can create 16:9 resolutions.

Looking for Fusion Fourty PNG ROMs V3.4?

712x400, NTSC HiRes Laced. How's that for aspect?


Ed: hence also 356x200, LoRes non-laced.

Those seem pretty close to the regular 640x400 and 320x200....so would they really be true 16:9?

To the poster above: I do have a graphics card (RTG).  I guess that's what I assumed was understood in my original post, but I guess I didn't make that clear.  So yes, I'm talking about creating a widescreen screenmode that is not dependent on the ECS or AGA native modes.

I realise that the mathematics might look a little involved but, trust me, it's worth it.

16 / 9 = ?

Okay, point taken.  Didn't realise it was that simple.  Never made custom screenmodes before.

I'll have to give one of these screenmodes a try.

OK maths time

16 / 9 = 1.777777 OK

320 / 200 = 1.6

1920 / 1200 = 1.6

1680 / 1050 = 1.6

1.6 as a fraction = 8/5 doubled up to make similar as above ratio = 16 / 10

So all my 16/9 monitor are 16/10. I've been miss sold monitors time to get my money back :)

But those are not the target display, which was for 16:9 (both LoRes and HiRes suggestions use "square" pixels). What are their physical measurements, so that one might correct for the aspect ratios if one should care that much? ;)
