Topic: Can't get any interlaced resolutions to work.
I've been using CRT Emudriver for many years on various systems now but this one has me stumped. First of all I will describe my setup.
I have a PC running Windows 10 in Test Mode.
It has a discrete low profile AMD Radeon R9 M360 that has two DisplayPort outputs only (card looks like this: https://i.imgur.com/t5bcGuu.jpg)
I am using a DisplayPort x VGA adapter which connects to an input on my Extron RGB 203
The Extron RGB 203 runs out to my Olympus OEV203 via 4 x BNC RGBS
So what I'm trying to do is get 480i and 576i resolutions working on my monitor.
I can install the modelines without any issue and they report to me fine in arcade_osd.exe, however, when I try to switch to them I have a blank screen with 'NO SYNC' on my monitor - and the Extron doesn't even report the vertical and horizontal scan rates like it does if I use a progressive scan resolution. It just says 'NO SIGNAL'.
The modelines I'm trying are:
720 x 576 @ 50.000000 aux
720 x 480 @ 60.000000 aux
but I've also tried these (in vain):
720 x 576 @ 25.000000 aux
720 x 480 @ 29.000000 aux
I'm thinking that the issue might be with the DisplayPort to VGA adapter. It's one I got from Jaycar here in Australia. I'd provide the link to what it looks like but am limited to one link per post it seems.
Happy to provide any further info on request. Thanks!
