Any retro system and LCD/Plasma TV's don't mix too well. Even when setting the pictures to 4:3 aspect you can still see that the picture isn't perfect. I have an old Sony CRT that is awesome for playing the old systems, including Amiga, on and the picture is perfect.

I've been using proper monitors/LCDs for so long now that when I see te Amiga output on a proper 15" CRT I think it looks fuzzy... Even though it does look "better"...

How about this?

http://www.ebay.co.uk/itm/Toshiba-42WH46-42-CRT-Television-/120839607036?pt=UK_AudioTVElectronics_Video_Televisions&hash=item1c229a12fc

Would that be the biggest and optimum crt display?

I think i would prefer Samsung/Sony to Toshiba...I haven't got enough room for a tv this size until i buy a new house :)

Is anybody using a 32 inch or larger lcd tv with a video scart lead without pixelation?

Edit: And i don't think using 20 inch monitors/lcd tv is the way forwards...I want a decent sized tv with surround sound for my 1200!
Maybe i still have an Xbox 360 display screen mindset and am asking too much from the old technology of the 1200??

Heck, even on my old 1084 back in the day, things looked strangely sharp compared to my friends who were generally running their amiga off a TV. The ones with 500s and 600s anyways.

Ok thanks bloodline, so what's the point of buying these scart video leads (optimised for new tv) if they give a more pixelated picture? Maybe it gives more detail but unlike hd, this detail is worse.
 
Its not clear to me why ppl buy these scart video leads and then rave about them

It depends on the upscaler in the tv. With a composite cable you're dropping detail and then the upscaler will generate new detail. With RGB you're just generating new detail.
 
Some TV's can achieve a similar effect to 2xsai on the right

Others just double the pixels and it looks like the picture on the left.
 
You could sit further away.

That would mean moving my sofa :)

I think you've hit the nail on the head there psxphill, my samsung led tv looks like the image on the left :rolleyes:

Maybe a combination of the tv being slightly big and me sitting fairly close (2m) away from it :) so i see the pixels and it reminds me of a commodore 64.

How do we achieve the picture on the right which the amiga is properly capable of, does the tv have to have a built in upscaler or is that something to buy separately? I've heard about indivisions but i thought that was to modify frequency settings of tv..

In the meantime i am using 4:3 scaling on my tv and it looks like something has swiped 15% of my screen at either side and replaced with black bars :(

As part of my professional degree I did some research on the suitability of using CRT's for the purpose of displaying eye sight test charts.  This was before LCD's.  One of the things I learned is that each pixel on a CRT does not have a square wave luminance distribution.  In other words the pixel was brightest in the centre and gradually dimmed out towards the periphery.  It mean that light from one pixel blended over the top of the light from an adjacent pixel.  This is what made graphic seems smoother on CRT's and less pixellated(but also made CRT's of the time unsuitable for eye sight test charts!)
