Has anyone tried on of these on thier Amiga?

[desiv]

You see the banding? Perhaps you'd never notice it? I would.

I can see the difference, but I'm not sure it would bother me too much.
I remember using my Amiga with an A520 composite adapter...  ;-)

But for $34 you can use a different one which is 24-bit!

Yes, that would be MUCH better!!!  :-)

This is just an extreme representation.

You don't "loose" colours, they round to their nearest neighbouring colour. AGA only has 256 palette entries. It is unlikely that games will choose all 256 entries to be shades of red for example.

But if they did, subtle shades are lost through rounding errors and are displayed as their nearest neighbour.

Yes you do LOSE colors when displaying AGA on a 16-bit display.  In fact, over 99% of all the colors are LOST.  They are GONE.  Eradicated.   Looks like crap.  Utterly useless.

Well put ChaosLord. Remember folks for each bit lost, your down by half the colours. That's colo-U-rs dammit, f'ing spellchecker, I'm British..... sorry, getting a bit side tracked on a rant just for a mo...anyway, yes , half your colours, 8 times over, and as the man above says, you've lost most of them.

True to a point, but keep in mind that even if only (for example) 3 shades of red are used, the chances are that even the loss of one of them can look real bad. Try drawing a circle in a paint package with a set 4 colour palette, white, red and two in betweens. Now edit the palette so that the two in betweens are the same colour by altering one to make it match the other, you'll see what I mean. It's not nice and it's not just a loss of subtlety.

I have done various tests with this piece of s*it, and i wouldn't recommend it to anyone and i agree with alexh, better option with less money.

 Yes, you can use that, it does work with monitors, but the quality is even less than you get with A520 on old TV, i wrote an article at Amibay about it, some time ago, with screenshots. If you get it free or let's say for 5€ (max price for that and still it's a robbery and you are not picky about colors, then maybe.

But as I understand it, you loose 1 of those three shades, it won't disappear.  It will be replaced by a shade that is "close" in the 16-bit range...
Is that likely something that will be noticed a lot?
I think it depends on the viewer and what's happening.  With photographs, more so..
With games, probably not as much...

Now, 24-bit is better, but 16 is no slouch..  :-)

IMHO

Case in point:
http://en.wikipedia.org/wiki/Color_depth
They don't even have a 16-bit pic, the the 8-bit pic looks very similar to the 24-bit pic to me..
Now, when I look, I can see the difference, but at first glance, not so much..

On some games, true, you'll barely notice, on others...yuck! It all depends on how the colours got used in the first place. as a general rule, lots of strongly different colours will be OK, subtle graduation will not. Truth is, I can't tolerate any loss of tone, hue or saturation in any way shape or form. I've done a lot of digital remastering (mostly martial arts movies) and I notice these things. I'm the guy who cringes when someone watches TV in the wrong aspect ratio or, god forbid, doesn't even bother doing the set up with proper colour bars. I also calibrate my printer and scanner to my monitor ...
... maybe I'm a little anal about these things but hey, we all have our quirks.

... maybe I'm a little anal about these things but hey, we all have our quirks.

You're not alone, every TV & monitor I've ever owned whether bought brand new or second hand, I've always taken the back of it to physically adjust the rings on the tube to get the perfect picture and adjust all the pots to make everything spot on...

The trouble with old CRT's when manufactured is they were only set to be adjusted to an "acceptable" standard that most folk would be satisfied with, while fussy buggers like me had to risk electrocution and do it ourselves to get the very best out of them...

But these adapters i see that have the YpCbCr connection type for components, and the amiga has composite out, so, how can one take out composite signal from the Amiga?. Using the 23 pin rgb port?. The reason i'm asking, is because i have already one of the vga boxes for connecting consoles that lack vga out to a lcd monitor, like the wii, and knowing how to get the component from the miggy i could be plugging my a1200 desktop directly to the tft monitor i have.
Thanks in advance!!!

These boxes need you to pull RGB and sync from your 23pin video out...

Meaning what? Impossible? Difficult? Easy?

I had the cv643d scan doubler that was 16 bit on an A4000.  Never noticed that it was missing colors.

[desiv]

Depends on how good you are at soldering...
It's something I could do, so I'd classify it as easy, but not simple.  ;-)

I am NOT any good with a soldering iron, but I can attach wires to things.

In general, does the Gonbes MODEL GBS-8220 CGA/EGA/YUV TO VGA CONVERTER

Easy. Simple wired cable
