Modern monitors are too big for that. You have to enclose a picture containing your wall too.

This request should be fairly easy to handle with a DOSBox build supporting shaders. All it really should take is a image of the desired monitor borders, and the overlaying of the DOSBox produced image inside of that texture. I won't be spending time to do so, as I don't find this to be useful, but it shouldn't be a hard request to accommodate.

Though I'm not clear that the way DOSBox handles shader resolutions won't interfere, since such may force the image generated by DOSBox to be downscaled. Such shouldn't be a big deal presuming you are running DOSBox in a resolution significantly higher than the game being run.

wouldn't it be nice if you were using that crt shader

with a picture of your old monitor and desk around that crt shader, displayed additively so the monitor blends in with the crt shader with little to none performance cost?

If you really, really want this, just write an HTML page with jDOSBox embedded with a picture of your monitor as the background. Don't want the browser window? Hit F+11.

Hehe, maybe something like the attached image <grin> 😀

Note that is NOT a "PhotoShop", but rather a compiled NeoBook Professional publication, with an "always-on-top" custom window with a transparent center... YES, that IS DOSBox running behind the window. Also note that was a really rushed $%itrig of a job, simply a proof of concept.

That being said, quite some time ago I created a similar thing for the BGB GameBoy emulator:

The inofficial dosbox port does something like that

Is there a way to do this without multipass shaders?

I have this wonderful kit of .cg shaders for Retroarch that produce an effect like this:

But it literally takes eight passes to make it look like a crap hand-me-down television from the 80s that we all used to play NES games on--it does wonders for them. Anyways, the border is what I'm really going for in Dosbox. I have some nice shaders + sweetfx setup and now all I need is a pretty monitor border to go around the edges.

Animating the image to fool people into thinking it is a real monitor is something of my dreams... but just having the image there, that'd be awesome alone.
