Thanks Brad, I'm afraid I don't use adPro or DiskMaster2 so can't test them on my setup, maybe someone else can.

Unless a program (whether an application or game etc) opens on a window in Workbench, automatically open in the same resolution as Workbench, or has its own prefs where you can choose the resolution, it will default back to using the native RBG output. It can't be forced to open via RTG. This is a limitation of the program, not of the video driver or PiStorm.

I've seen things on twitter etc about a video passthru from RGB into Pistorm which is in development, but I think this involves hardware too. I'm not sure.

Andy, I am using the ScanPlus AGA cards for my VGA. Like wise if I start an app that uses VGA, my screen goes black until
I switch my monitor back to VGA. My goto file manager is DiskMaster 2 and my go to Image manager is ADPro. Neither of
these will open in RTG. Even DOPus 4 freezes most times I open it up. They are working on making this video driver as
compatible as the WinUAE one, no  Any idea how to set these screens to except RTG mode?
Thanks for the support,
Brad Hansen

Great news that you have sorted the main RTG issue. The first time I saw my real A1200 output workbench in fullHD was a special moment. I'm impressed by how smooth the UI looks.

For your VGA / HDMI issue, do you mean you are using a scandoubler or something so the Amiga native video is connected to your monitor via VGA? If so I have a similar experience but my screen goes back to the SCART input on my TV.

Can you name a couple of Apps that take you back? Maybe they don't support RTG screen modes, or they open up their own window and the resolution needs to be set separately.

WinUAE is a bit different, and so even though you have Workbench set up with RTG, the different apps may be using different screen modes but the switch between them is so fast, and in the same emulated window as to be practically non existent so you don't see that the output has changed because it's still in the same window, it's just switched between screen modes.

Andy, Thomas, Success! Hi, I have succeeded in getting an RTG Devs/Monitor working. Andy, followed you link and understood that in Picasso96mode under "Attach Settings," it often showed me "Board0: VideoCore." So I went into Dev/Monitors and
for the RTG monitor I had chosen when I installed Picasso96, I changed that name to "VideoCore." Back to Picasso96Mode
created a new listing choosing "Board0: VideoCore" and I was then able to add RTG modes there. Restart and in Prefs/Screenmodes
I found the new RTG modes I setup. My monitor can switch back and forth from VGA to HDMI. So choosing the RTG mode and
switching to HDMI I was able to open and use those modes. Wonderful stuff, but I encountered a number of issues, a number of my
most used and favorite Programs can only use VGA modes to view them.? When I am running Amibian and running my Pi separately
I have no problem launching any of those programs in RTG mode using utagfx setup of Picasso96. First thanks for all your help,
really great. But any idea why that is?
