Monochrome monitor/greyscale notebook display emulation

Emulation of old PCs, PC hardware, or PC peripherals.

Monochrome monitor/greyscale notebook display emulation

Postby BlueSkullKey » 2018-9-09 @ 04:39

Hello.
Please tell me if there are any standard ways in any emulators to emulate a monochrome monitor. :?: :sweatdrop:
I've mostly used DOSBox (will setting machine to hercules in .conf do it?) and briefly PCem, but am interested in this in any PC emulators, especially ones like later.

Also, as I see people trying to achieve CRT looks in emulation, I wonder if anyone tried to do something like that, which would imitate the old notebook computers display looks? Those greyscale TFT LCDs and DSTNs and such. They've had a very peculiar looks, I think, maybe because of backlight, I don't know. Like these

UniPCemu also supports monochrome monitors using MDA and VGA palettes. Simply set it to either device and set the black/white setting to either amber, green or white(in the video settings). Although the setting won't have any effect on CGA and SVGA modes(since they don't use any color palettes).

Although UniPCemu doesn't support any shaders or the like, like Dosbox does.

I tried to hack up a Compaq mono LCD shader for PCem once in 2017. It was just a rough color gradient blend + drop shadow shader. It hadn't looked right because PCem doesn't emulate many laptop video chips that do 640-wide text on VGA and etc, and I didn't hack in the shade reduction

Youtube is updating to HD so higher quality should be available soon.

It's awesome that it has those settings. Sadly I couldn't try them out yet, because I can't get the emulator to work for some reason.
First I couldn't quite figure out ROM filenames (is BIOSROM.BIN right?), it would be better if there was a table with them somewhere in your wiki, because I don't think filenames for video ROMs are mentioned anywhere there.
But then I just get a black screen with access to settings, if I set it to show CPU speed, the speed changes sometimes, but that's all. I've tried various ROMs, tried to use internal ROMs, tried changing different settings, all the same. It's 64-bit version on W10. Either I miss something obvious, or something goes wrong in a weird way on my system.

Nice. At least makes me think that it's possible. Too bad I don't know much about shaders yet.

It's close, but not exactly there. Maybe it's hard to judge the ghosting thing by video though, seems too little :lol: . There were also several types of those displays, and they've had it to a different extent. I mostly remember the mouse pointer having a trail, and it was Ok to play some DOS platformers on my notebook with greyscale screen, while on others picture in those could become seriously blurry. Well one of their main uses was something like MS Office 4 rather than games probably :) Notebooks like these

@BlueSkullKey: I've placed some information about the ROMs to place in the ROM subdirectory on the Settings menu page, https://bitbucket.org/superfury/unipcem ... ngs%20menu .

Under Advanced menu, for the option Boot with BIOS ROMS it lists the filename structure for normal BIOS ROMs(the machine's main BIOS ROM at the end of the memory).

I've added the video ROM information as a seperate section directly under that.

Now it lists all possible BIOS and Option ROMs that UniPCemu supports.

Funny enough, that is the exact laptop I had for college. :) I remember it well.

I think there's a way to increase the ghosting in the shader I made a video of by tweaking a few things. Unfortunately I'm not a shader expert, so it would be through trial and error.

a couple passes of shaders/misc/motionblur.glsl should do the trick.
