We already tested many different monitors and HDMI to VGA adapters successful. Can you kindly share some images?
Can you borrow another monitor from a friend to test?

Thanks!

Hi Stephan,

I have a VGA switch, but everything else going thru it is fine (QL VGA & TI-99/4a VGA)

Will try and get a picture

I’ve managed to get a working image by passing the Qimsi Gold VGA output thru an OSSC to HDMI.

Thanks

Difficult to get an image due to the way it scrolls and flashes in and out

What is "QL VGA" as the QL has no VGA output?
With which device did you convert QIMSI to VGA?

By “QL VGA” I mean a QL to VGA device like Chr$/techy sell

The QIMSI gold has a simple MiniHDMI to VGA cable (also tried MiniHDMI to HDMI). The OSSC solves the issue which suggests my Sony doesn’t like the signal it gets for some reason

So, this means you have a working solution providing a good quality picture out of your Qimsi Gold?

Yes. I need to adjust the OSSC though as it seems the image goes off right hand side of screen slightly.

Many thanks

I don't know what they sell. Any info what it is? Which resolution does it generate at the output?

To what did you connect the MiniHDMI to HDMI cable?

Techy’s is as per this thread viewtopic.php?t=4543&hilit=Ql2vga

It shows as 1024x768/60

I connected the Qimsi MiniHDMI cable to an HDMI input on the TV (tried all 3 just in case)

It is a Sony KDL - 26V4000

Thanks

Thanks Tony, and also for the further infos provided by PM. In conclusion, I see a timing incompatibilty between QIMSI Gold and the rather old Sony TV.
Since the vast majority of monitors were successfully tested with QIMSI, and you have a workaround with the OSSC, we have decided not to risk experimental FPGA changes for this particular TV.
