I have a PC monitor with a 14v rating but it's original DC adapter is broken. Can I safely use a similar DC adapter from a similar monitor, but with 15v output instead? How likely is the 14v monitor to suffer a burnout?

The power adapter probably feeds into a number of voltage regulators or DC to DC voltage converters so the circuits will get the proper voltages ahead of the adapter. Equipment is designed so that it can handle a certain range of voltages to allow for voltage drift caused by aging components and/or other problems caused by open capacitors etc. I have never needed to change an adapter for a monitor but have replaced adapters that were not exactly the same voltage as the original for laptops and other equipment and have had no problems. If this were my equpment, I would try the adapter provided it was the same polarity. Reverse polarity will definitely damage the equipment but one volt higher probably won't make any difference.
