What are typical shutter speeds to use when filming a scene with a computer screen?

Whenever I shoot a scene with a computer screen, I always have to play around with shutter speed to find the right one so I dont get a scrolling bar. That said, there are probably common shutter speeds which get rid of that, speeds I could try first without having to resort to trial and error. What might those be?

Yes, ideally you'd need a camera that has a "clearscan" mode... which is really nothing magical, rather it's just a way of very precisely controlling the exact shutter speed.

It may differ a little bit depending on where you are (and certainly will differ with where you are in the world), but here in North America most of our AC electricity runs at 60.1 Hz... therefore, you need a shutter speed of 1/60.1. That's what we typically use when shooting screens.

If your camera doesn't have a clearscan mode, you'll just have to play around with shutter speeds until you find one that works. I'd first try slightly lower speeds, and if you can't get a workable one then go a little faster.

In a real pinch, if you can't get computer screen to shoot clearly, you can leave the camera as it is and adjust the refresh rate of the monitor itself (control panel > display > settings > advanced > montior). You might be able to find a setting that looks better on camera.

Can you find one that has an LCD monitor?
