They list it as working well to allow Amiga's to work well with modern flat panel televisions.

I'm looking to buy one of they work well.

If I had money for every time someone posted about them I'd be rich.
They are shite. They are only 16-bit which means you loose colours in AGA. They promote PAL screens to 60Hz which means that you loose smooth scrolling.
There are better, cheaper alternatives out there.

Gotta agree with that, if you want a decent convertor your gonna have to pay through the nose for one. Worth the money though if it's something you use all the time and value the best picture quality... :)
I always buy such things from Keene Electronics, quality made and built to last for years but you're looking at around £100 minimum for their basic stuff... :)

All true, but there are a few levels to the question..
Are they great devices?
As answered above, no. You will lose some colors and you loose something in the PAL transition..
The other side of that question is how well do they work other than that?
Yes, you lose color, but how badly?
Yes, you lose smooth scrolling in PAL conversion, but you can use PAL games then?
They might still be worth it depending on what someone is looking for..
Personally, at that price tho, I doubt it..
With those short-comings, I'd still be very tempted at $50 or so... Just to have them..
I went with an Amigamaniac SVIDEO adapter, and then an SVIDEO to VGA adapter.
Unfortunatly, the model of SVIDEO to VGA adapter I bought was bad, but there are good ones out there, and the results are pretty good I think. Still not Indivision, but.. nothing is at that price..
And for all of that, I then got a few 1084S monitors, which I'm very happy with.
Go figure.. ;-)

More MOD Shananigans! :roflmao: Yeah, like Pyromania with his over 1100 posts doesn't know that! Even Franko fell for it! :hammer:

But for just setting up a system until you get RTG up and running, I'm sure they are fine.
I'd rather have one than the rarely used 1084 on my desk.

Hey don't be badmouthin' the 1084. I rather like it.

I used this one and it works relatively good

Is this becaus US tvs doesn't have scart connectors???
I've use my samsung TV ages now through scart, picture quality is really good

I had one of those until it died during an apartment move.
Upsides:
Its cheaper than an indivision (and you can actually buy it)
You can use a cheap off-the-shelf monitor
Its pretty decent. Certainly fine for gaming.
Downsides:
A bit of ghosting appears. In games you probably won't notice, but on workbench, it can be annoying.
I thought scrolling was fine, but occasionally it can be a tiny bit glitchy.
These are not very noticeable though.
It does NOT play nice with interlace modes at all. About half the time I try it, the picture is garbled, and half the time it looks great.
General info:
They produce a nicer picture on a CRT than on an LCD
In the end, while there might be better options, this is certainly usable and I used one daily for a year or so, without any fuss. The loss of image quality is not really that bad.
edit: and yes, no SCART in the US.
1084's are cool but they are also getting old. Considering the cost of shipping the blighters, Im not sure if its worth it.

24-bit and known to work well with classic computers.

Yes, you lose color, but how badly?
Look at the 2 images below. The first one is 24-bit, the second 16-bit. You see the banding? Perhaps you'd never notice it? I would.

Sure but they look rubbish.

But for $34 you can use a different one which is 24-bit!
-
WOW! Looks like hell in 16.
-

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... ;-)

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.

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.
-
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
