Adding widescreen resolutions in Windows Virtual PC

[Zero3K]

Is it possible to do that? I want to be able to have it be at 1920x1080 (with width and height subtracted for the menu bar, etc. that are a part of Windows Virtual PC). I am using the driver available at https://u.teknik.io/WiUU8.zip (It doesn't have graphical issues, etc. like the drivers that come with Microsoft Virtual PC 2007 and Windows Virtual PC).

Check, maybe the registry trick will work or files from update for VPC 2007:

In WinXP and newer try edit DefaultSettings.XResolution and DefaultSettings.YResolution in regedit key:

Code: Select all

HKEY_LOCAL_MACHINE\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Control\VIDEO\{video card guid}\0000

Edit system file in regedit WinPE with Load Hive option.

1. The driver from VPC 2007 does work but it causes graphical glitches to occur (which is why I want to use the driver that I linked to).

2. Changing the mentioned registry entry didn't work. I changed all the keys in the VIDEO folder with no luck.

What host operating system and what guest?

Host is Windows 7 SP1 (64-bit) and I am using multiple disk images as VMs (one has Windows 7 SP1 (32-bit), another has Windows Server 2003 (32-bit) and the last is ReactOS (32-bit)).

I'm suspecting that you want to do the same thing what I wanted before and asked on BA before, though I was using VBEMP9x. You seem to be using non-VPC driver for Windows NT 4.0, so I'm guessing that's your guest OS.
Though, Beta12 already mentioned my thread, but it's not an actual solution:

I'm guessing the graphical glitches are ones where you can see leftovers while dragging stuff around or whatever kind of glitch that doesn't occur on non-VPC drivers.
As far I've tried, I couldn't do much to make it widescreen with non-VPC drivers. I'm not sure if messing with Video BIOS would work either.

Unless there is a custom driver that supports widescreen on VPC, there is nothing much else that can be done.

There is VBEMP driver for NT, but unless specifications mention support for widescree on VPC or S3, I doubt that it will work: http://www.navozhdeniye.narod.ru/vbemp.htm

I tried the VBEMPNT drivers. They resulted in BSODs.

Didn't a VPC Rollup add these "widescreen" resolutions? https://www.betaarchive.com/forum/viewt ... 87#p369687

Note that MS has shutdown the download links, but you can still access the files through the WebArchive WayBack Machine

Edit: Just realized it's Windows Virtual PC and not Microsoft Virtual PC. This solution works for MSVPC though, so you could theoretically plug the hard disk of a WinVPC machine into a MSVPC machine and boot, and it could probably work (because both programs share their codebase to some degree)

VPC Rollup does indeed provide support for higher resolutions. I was able to run Windows 98 VM on VPC 2007 with Full HD before (though VPC on my new PC works with strange stuttering, most likely incompatible with my PC configuration, which ended up with me using VMware Workstation instead).

However, those are available only when VPC Additions drivers are installed in guest VM, non-VPC graphics drivers will not provide widescreen resolutions.

Take note what was mentioned:

1. The driver from VPC 2007 does work but it causes graphical glitches to occur (which is why I want to use the driver that I linked to).

VPC graphics driver will provide higher resolutions (including widescreen support), but this still won't work with graphics driver that are not part of VPC additions.

As a tough workaround, I'll have to suggest using VMware Workstation instead (with 6.5-7.x configuration most likely) with Windows NT 4.0 as it might not have same graphical glitches like on VPC.

Also, Zero3K, can you show any examples of graphical glitches on your VPC? I want to see if it's exactly the same issue like mine or something else.

VBEMP is used in ReactOS by default (I think). In ReactOS, the default driver doesn't let me choose a resolution that makes it almost the size of my monitor's max resolution.
