Sorry, there hasn't been much progress, just a little re-design in the PCB, but still not finished.

Ok guys, ordered PCBs and parts for another 10 pieces. Some minor tweaks and a power LED has been added.

I will post the updates after the parts arrived.

Have you tested with NEC Multisync LCD 1990 FXp? I have Tenox adapter picture is not very stable with it. If this one makes stable picture (no horizontal flickering) I am also interested to take one.

Sorry, i'm not even have my own atari TT --- no way I could get one of said monitor.
However during development, one TT from the 2 was available for me in HighRez mode had quite bad horizontal sync (fuzzy lines, unreadable screen) and after some time it cleaned up (maybe weak power supply?)

My adapter does almost the same as the Tenox, but can be turned off/on and only need common mini USB-B as power connector. Also has case too.

Does your adapter make something with the H and V sync signals, or it just passes them through?

If switched to Hi-Res mode, the H signal get delayed a bit, otherwise the picture would be too much in the right side.
In normal VGA mode both H and V transmitted uninterrupted.

6 units are still available!

A bit extra info:
-it has a bit better connection-- totally separated input power (no ground-loop issues) -- older one may have issue if the connector shielding is connected to GND
-has power indicator LED "hidden" inside the case, if better visuals needed, you can drill a hole for it..
-consumes only 70mA in idle/VGA mode and ~85mA in High-Resolution/ECL mode
-switch is smaller, only the handle hags out from the case

It has arrived and it works great! Thank you, CodeKiller! :D

There's a moiré pattern but I just played with it quickly to adjust the image, might be able to clean it spending some more time adjusting it. Also the LCD monitor is a chinese low quality one I have around (17" Haier branded).

Yup. this adapter only translates the signal type but not scales the image. It has to be adjusted in your monitor.
It looks like your monitor scales vertically -- the TT's image width is pretty standard 1280px, but the height is the not so common 960px -- maybe it tries to stretch out to 1024.

All the monitors I've tried will scale vertically and cannot reduce size. There will always be some moiré at high res. Best way is either all white or all black background. On the other hand I think it's for the best since old CRT monitors were 4:3 ratio and newer non wide LCD are 5:4, which means the pixel will be square. You can confirm this in the pic I took, the icons and text are well proportioned.
