Hi BGPhilbin: Thank you very much for contacting the Intel® Graphics communities. We will do our best in order to try to fix this problem.
At this point you tried almost all the troubleshoot steps that we recommend to try to fix this issue. You mentioned you already re-install the latest graphics driver, just to make sure, on the link below you will find the version 4849, after the installation of it, please verify the resolutions available to choose the proper one:
If the problem persists after that, since you are using an HP computer, we actually recommend to install the drivers provided by the manufacturer of it and try the steps above once again:
Additionally, even though this is also a very basic suggestion, most of the monitors have an option or setting to increase or decrease the size of the display, sometimes the size of the screen gets bigger that it should, we had some cases where the issue was related to that feature.
Any further questions, please let me know.
