Has anyone managed to get the board powered from the power provided by Amiga's DB23 video port?

I wouldn't try it as the Amiga port doesn't really supply enough current.

The +5volt from the Amiga video port is meant to be 100ma max, the GBS video converter needs about 400ma minimum.

the power figures from the amiga are probably fairly "safe" figures...

if you were to regulate the 12v @ 100ma, you'd probably be able to get 5volts @ 200ma ;)

combine that with the 5volts @ 100ma...

I still wouldn't do it though! lol

The output is OK....

if your only choice is the GBS, or composite, then the GBS is fantastic....

It'll never be as good as RBG/scart, it does weird things to the video.

I'll try to take some good pics later, comparing scart to the GBS, on the same monitor!

GBS set to 1024 x 786, which is this LCDs native resolution...

It will often create weird banding in solid colours, or patterns, whereas the scart displays it as a proper, solid colour...

Keep in mind this monitor is rubbish, and doesn't display any image properly centred :whack:

GBS


SCART


The GBS also creates these weird patterns around the mouse pointer... I didn't even bother photographing them.

There's also often a weird ghosting around text, as mentioned before, this screen isn't great, so the scart image looks a bit odd too :whack: you can also see in the following pic, that along the row of "D" in HD0, HD1, HD2, etc, its blurry.... the GBS doesn't do a very good job of upscaling... grey also seems to be displayed slightly blue, although you can probably adjust this ;)

GBS


SCART


SO! if you're needing a way to connect your Amiga to an LCD TV for playing games, then I'm sure you'll be more than happy with the GBS.

Yes, each second photo is scart.

I sent the workbench backdrop to a very fine checker board pattern... I think? :p

This is the GBS attempt...


VS the SCART.
