I did think about putting it behind a "bezel" or something, but making it push through would be much more preferred. I quite like the Push through design, and the screen to the left and the rest down the side. But then I do also like those 80s sets which had the screen central, and a loudspeaker each side.

That sounds like a good idea, It'd be interesting to see it done!

It would be good to mask it at 5:4, too.
Now that we have a 405-line 5:4 converter, the opportunities are limitless!

That could be pretty interesting, I've never seen the 5:4 ratio 'til now, I just looked it up.
It seems like a pretty interesting concept to do with these little TV sets, to customise them, they seem pretty versatile too, what with the extra technology with have which we can add to it!

The change from 5:4 to 4:3 happened allegedly* on the 3rd April 1950. I doubt the public even noticed

Much the same as when Radio 4 got stretched by 15 meters 38 years later.

*I mean did they really manage to adjust every camera and flying-spot scanner in the company on the same day?

Was 5:4 used on TV? I always thought TV was 4:3 then 16:9, apart from the squarer TVs, unless these are 5:4?

When I searched 5:4 it just came up with photography photo sizes, not much reference to TVs, but there were for computer monitors. Is this a 5:4 AR screen? (I have one and realised it might be)

Thanks

The original Marconi-EMI system was 5:4 ratio. The competing Baird system was 4:3, and relied a great deal on cinema technology.
The first BBC Baird system was 7:3, but including a 3% black synchronizing bar. The bar was widened (unofficially, according to Campbell) to 10% in order to improve synchronization, some time in late 1932 or early '33.

I think a lot of the monochrome CRTs were 5:4 well into the 1960s, and it was expected that a modest amount of horizontal overscan was applied.

That makes sense, I did always think that the CRTs did look different from late 60s and onwards CRTs, this explains why. I thought it was down to manufacturing techniques at the time and limitations. As you say, I didn't even notice this (not properly anyway)

Thanks

5:4 nowadays is the most popular non-widescreen format for computer monitors. 1280x1024 pixels, mostly 17" or 19" diagonally.

Ah, I didn't even realise they still make non-widescreen monitors still, but it doesn't surprise me.

Thanks
