OK, here's the early results on my VT-521 adapter I got. While not a flicker fixer, it does allow me to run my Amiga 500 (NTSC) on my VGA monitor.
Currently, I'm using composite output from my A520 adapter, and it's acceptable.
I assume with the s-video mod I'm thinking of doing to the A520, it would be even sharper, but I think it already looks a bit clearer than it did on my LCD TV I was using. (Probably do to scaling or ??)
First that that caught me off guard, it came with an adapter with a 220V plug. I found an adapter that was close enough, but wasn't comfortable with that. So I opened up the wallwart plug (just 2 screws, not glue!!) and hooked up a regular plug to it, so now I am using the correct plug. (For some stupid reason, I didn't unravel the wire until after I did this and realized the plug was actually pretty short, maybe 2'. I could have used a much longer wire on my plug wire I added (probably will go back and do that still) and I should have checked first, but it works..)
I took a picture, but I have to find a place to upload it to. We are moving and my webspace is closed on my old provider and not up on my new one..
Basically, it has 3 inputs. VGA, composite, and s-video.
The device comes with a VGA cable, composite cable, and an s-video cable. It also has an RCA to BNC adapter for using if your composite video source is BNC. (Not an adapter I ever had, so kual, although I doubt I will ever need it..)
Basically, I plugged it in and it worked. There is a button for source, and it toggles between the 3 inputs.
You also have full control of brightness, contrast, saturation, and hue (and a reset to default). Brightness was pretty low by default, so I upped it...
It also has a "Freeze" function that I haven't tried..
As I mentioned, I could get PAL to work, but my I had to toggle off and back to the composite input to get it to recognize that it had flipped to PAL (I used a game that let me left-click to choose PAL on the bootloader and the picture kept rolling until I reselcted the input) and my PAL is monochrome. No color.. Not sure if that's the device or the NTSC Amiga doing PAL or the A520 trying to do PAL....
Oh, almost forgot (OK, I did and I'm editing this in)
It also lets you select your output resolution.
Resolution: 800*600(60Hz), 1024*768(60Hz) and 1280*1024(60Hz)
I didn't notice much difference on my CRT (I did see some scrolling sparklies on 1280, but that could be the included cheaper vga cable or ??). I assume it would be useful if you were using an LCD and trying to match the LCDs resolution...
So far, it's an intriguing little device, and if it lasts should be useful for hooking my old computers/games to my VGA monitors...
