Scart to HDMI Converter

Post by Sausageinabun » Mon Nov 13, 2017 8:35 am

I bought one of these at the end of last week and it arrived late Saturday. What with the recapping I didn't get around to plugging it in until late yesterday, and wow, call me impressed!!

This little box is excellent, especially given the price.

I was, up until now, using a scaler, (GBS-8220) to give me VGA output, but the quality on this little box is IMHO far superior.

I am so happy with it, that I've ordered a further two.

I have one of these. They look good when playing games but, and it's a big but, there are a lot of artefacts when you use the desktop.

The menu items pop and the edge colours lag the centre of the highlighted menu item. There's also a large lag, which can make mouse pointing (and game playing) a problem. You can test these issues by going to the desktop and select the 'File' menu and move the mouse rapidly up and down. You can also see some artefacts if you open the "About" dialog and wiggle the mouse along the bottom border.

I have tested two of these converters (along with a HDMI to VGA converter). One mentioned here is number 2:




I've more liked number one and this one I've kept, the other one I've sold. Number 1 doesn't do as much image sharpening, has option to set SVGA and XGA output resolution (not only 720p/1080p), and desktop colors more resembles what I remember from my CRT monitor (which wasn't Atari brand monitor). Number 1 green is apparently too light (and it was so on most of the RGB CRT monitors), there was some issue with video levels, so the green on number 2 is more close to what is was meant to be (but it wasn't on all but one variant of SC1224).

Thanks for the videos! Number 2 does indeed look rather nice from what I can see!

I thought that people here might be interested in a converter (not really cheap) but absolutely the bee-knees if you want to display a TT on a modern LCD TV... The Open Source Scan Convertor (OSSC).

I ordered one from here on Monday and it arrived today: https://www.videogameperfection.com/pro ... converter/

Well, after some tweaking all I can say is that I'm amazed at the quality and almost complete lack of lag.

Here's an example of TT-Medium mode (it looks better in real life):

The settings used for this:
Sampling opt>
Allow upsample2x: on
<640x480 Adv Timing>
H.samplerate: 1023
H.backporch: 126
V.backporch: 29

Output opt>
