(S)VGA itself (analogue RGB with separate H/V sync) has no concrete theoretical upper limit, AFAIU. 2048x1536 is likely a common limit imposed by the RAMDACs that are (were?) available either as discrete components or integrated into VGA controllers (or GPUs). I have no idea if CRT monitors …

How is the HDfury X4? It’s listed at 225 MHz but only has an HDMI port. That has a scaler rather than just having a DAC going from digital to analog. I also could be wrong, but I believe VGA will top out at 2048x1536. Honestly, the cheap DP to VGA adapters offices use to get new computers working …

Thanks for including what you are actually trying to do. DxWnd intercepts the CD calls and has its own CD player which was created to allow the proxying of audio files in place of actual CD playback. This allows the playback to happen in its own process and thus volume can be controlled separately. …

Are you using Windows 10/11? If so any reason you can't use the volume mixer? Right-click the systray speaker and choose open volume mixer. It should list all applications and you should be able to adjust Coolsoft's volume. Another option is just pressing windows+G which will open the game bar. One …

Do you just want DisplayPort to VGA? The Sunix DPU3000 you mentioned was a triple display device that had DP, HDMI, and VGA output. Pretty much any DP to VGA adapter on the market handles up to 1080p 60hz. Maybe go with a $12-15 adapter versus the $7-8 if you are worried about the quality. But do …

The biggest issue which was already mentioned is the single PCI slot. Even if the board has drivers 3D performance is generally not great. So you are stuck with getting a PCI video card and then sticking with the onboard audio. If you already have the hardware, give it a spin. Worse case it's too …

I don't have a readily available Win3.11 install, but going off the ol' memory in the control panel there should be either a MIDI option, or it's limited under multimedia. One of the options should be the MIDI mapper which lets you choose the MIDI Output port to use. Do you see anything like that?

Does the audio light on the CM 300 blink at all? If there is MIDI activity should flash or at least be lit. Have you connected headphones or speakers directly to the CM 300 and see if there is audio coming out of it to rule out an issue with audio mixing on the AWE64?

Thank you everyone for your help. May try bridging the connections in time and hopefully this will correct the issue. Bridging won't help if that's really the problem. If the switch is stuck then the connection is already bridged and you need to break that link. The repair will require replacing …

Unfortunately, it looks like you can only do 1.5x,2x,2.5x and 3.0x according to the manual. The P55C 233 MMX is wired so 1.5x = 3.5x internally. From the manual, but it could vary based on board revision. But there are six switches. The first four switches control the bus speed, you'd want this set …

There's also the USB4VC which you can DYI or you could buy assembled. https://github.com/dekuNukem/USB4VC/ It's set up for a full Raspberry Pi, though I believe an old original will work, so you don't need an in short supply 3/4s. It gives you PS2/AT/XT keyboard, PS2/Serial mouse, and DB15 Joystick. …

There are inexpensive VGA->HDMI some people have luck with. But I haven't gotten them to work. I bit the bullet and got an OSSC which works great. However; the OSSC wouldn't be outputting 1440p. With a 240p signal you can get a 3x scale to 720p, but higher resolutions will max out at 2x. There is an …

Ya, it's likely a limitation of that BIOS, you aren't able to partition and format the card in the laptop with Win95 media?

Try partitioning and formatting the card on a modern PC and get DOS booting on it. Just the system files so you can boot, you don't need a full installation. Then copy the Win95 installation files to a directory on the CF card. You can boot off the CF into DOS and then launch the Win95 installer. …
