Yes, if you can find one and if your images are correctly tagged. The monitor should naturally be properly calibrated.
Adobe RGB and sRGB are pretty close, even if Adobe RGB primaries stretch farther in the blue greens. You can probably get away with showing Adobe RGB on an sRGB system even without correctly handling profiles. Prophoto RGB is another matter, it will be obviously bad.
That is actually an advantage with Prophoto RGB, it's obvious when wrong!
My 2 cents:
- If you have an Adobe RGB capable monitor use Adobe RGB
- If colors fall into sRGB than choice of RGB will not matter, but it may be that you get better tonal separation in sRGB
- Use ProphotoRGB as working space, this way you will not throw away colors that would be outside sRGB or Adobe RGB
- Export to sRGB if you are not absolutely sure that the recipient knows what he/she is doing
So it has nothing to do with the monitor but the application?
Meaning, for example, if I am showing a "slide" show on my monitor using an application that understands what color space the image is in (like Photoshop does), then the result should be ok?
