I've just finished repairing a failed Acer AL1912 LCD monitor in which an electro in the main switcher output had pulled the system down. All the electros are 105C and measure higher ESR than I'd like, so they will all be replaced while I'm in there as routine.
There is no indication whether the existing ones were low ESR or standard. Is there any potential issue if I fit low ESR in place of standard, or vice versa?
Generally speaking low ESR capacitors are always the better choice for power supplies as they will run cooler.

Electros in switchers should always be low ESR types.

If they are in the output of a switcher, it is a reasonable bet that they are low ESR. Replace with low ESR anyway.
