I revised my PNG setup icons for ArcaOS.  Added a few more icons.

Thanks for the suggestions.
I am using Virtual Box 6.1.18 under Windows 10 64 bit (and also Ubuntu, but I checked your suggestions under Windows)
I left monitor unselected, as I had seen Martin's page with no monitor, but wide screen working
I am using VBoxVGA and I increased video memory to 32 MB
I had been trying 1920 x 1080 x 32, but then I saw your suggestion, and I changed to the native 1920 x 1200. Both Windows and ArcaOS are fine with 1920 x 1200 x 32. Unfortunately, this change did not get VirtualBox to cooperate.

My OS2Addtions are dated 8-15-20. These do not have VBXGRADD.DLL

1) what version of Virtualbox are you using ? I am using 6.1.16 on a Win64 host. I cannot use 6.1.18 for a completely different reason: it breaks DHCP support in the guest in conjunction with E1000 as MAC driver selection (which I have already reported and which will be fixed in the next VBox release). I am asking, because there is always a chance of some regression sneaking into versions. It would be helpful to start from a common base ...

2) the monitor I picked in the OS/2 guest is "Vesa 17 inch, VESA standard". I doubt that it would make a difference considering that "Vesa 17 inch" is a config/standard that is about 25 years old.

3) what "display type" have you selected in the VBox configuration ? Should be "VBoxVGA" which is the default. The documentation explicitely says to not change that.

4) 1920*1080 * 4 = about 8 MB should be enough for screen aperture (my resolution as an example). I set it to 16 MB.

5) I am not sure in how far VBox has to use real mode BIOS or emulate real mode BIOS services to support custom screen resolutions. As with Panorama, this might cause limitations in what can be offered as a custom resolution. Do you have a native installation of OS/2 on that very same machine and can test with Panorama what it would support ? Is your desired screen resolution supported in the host as well (in my case, I picked the max resolution that Win64 can do on this computer) ?


EDIT: I can confirm for 2) that selection of monitor is completely irrelevant.

I am using Ubuntu Linux, but I also have a Windows 10 host. I am quite unfamiliar with Windows 10 and Ubuntu, but I thought Virtual Box might be helpful to develop. I've tried to follow your instructions, and those at Arca Noae, but nothing seems to set that resolution.

Your helpful Wiki helps me see that monitor definitions are not the answer. But I'm still unsuccessful at adding any wide screen video.

But so far no joy with getting a wide screen resolution.

Hi Neil

I have some VirtualBox notes here: https://www.os2world.com/wiki/index.php/ArcaOS_5.0.x_as_a_VirtualBox_6.x_Guest#Video

Which is your VirtualBox host?  In Windows 10 I had tried this command to get a higher resolution on the ArcaOS guest and worked.
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "ArcaOS 5.0.3 (Name of the VM)" "CustomVideoMode1" "1920x1080x32"

Regards

I tried VBoxManage and I am using the same GRADD.DLL as Martin. But so far no joy with getting a wide screen resolution. The screen applet suggests that I select a monitor to enable higher resolution, but offers me a list of monitors from 1996. Did anyone using a wide screen select a monitor? What did you choose?

For what it is worth, I do see a slight flicker to the cursor at 1280 x 1024. It's not crippling, but I think original poster is right that it is a little slow.

There's always the option of running at 64K colours. Even on real hardware, Arca Noae recommends 64K colours for maximum performance. Less memory per pixel and doesn't look much different. Of course depends on your usage.

So I did a fresh install and still see it.  If I run the VM in fullscreen mode, it acts better but is still slightly laggy.

If I build the VM under Parallels instead using Panorama, it works fine.  So it must be some weird macOS + VBox + OS/2 GA issue.

Sorry for the noise!
