I think that the question is, can you use a display near the magnet, inside the RF shielded room?
The short answer is, No, unless it's specifically marked MR-safe and/or included in equipment that's specificaly designed to be near the magnet, such as an injector.
The problem with using, for example, a monitor from Best Buy is that it will probably emit RF energy that will corrupt the very weak MRI signal recieved from the patient's body. Of course, there is also the question of anchoring the monitor to prevent it from being attracted into the magnet.
In general, an off the shelf monitor will not be affected by the magnet.
You can buy special RF shielded monitors, or enclosures.
If you were thinking about adding a patient DVD viewing capability, there are several other concerns to keep in mind. The signal feeding the monitor must be filtered where it enters the RF shield.
