Re: Custom TV
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! |

Re: Custom TV
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! |

Re: Custom TV
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! |

Re: Custom TV
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 |

Re: Custom TV
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. |

Re: Custom TV
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.

Re: Custom TV
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)

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

Re: Custom TV
Ah, I didn't even realise they still make non-widescreen monitors still, but it doesn't surprise me.
Thanks |
