<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I just went through this as we changed our breast PACS vendor which required a change in the computer tower that all the monitors were plugged into. I treated this situation
as a “new installation”, and did monitor testing before the radiologists started viewing images on them. It turned out to be pretty valuable, as some of the monitors weren’t properly set up by our IT team. It was all simple issues, like an issue with improper
Windows scaling (should be 100%), or Windows not correctly identifying certain monitors. So even though you’d be reloading the same software, if it’s a fresh OS install, I’d say it’s best practice to treat it as a new installation. You’ll also want to make
sure the QA Web (or whichever auto QA program is used for that monitor) was properly installed and the QA tests are all running on their schedule.
