Update - my concerns about the graphics chip on the EB1503 were unwarranted. When I installed, I configured the OS to use the NVidia 'GeForce Series 400 and later' driver, which seems to work fine. For the monitor, I just selected the generic 'Flat panel 1920 x 1080' option. I installed the KDE version of PCLOS, and everything seems fine except no sound yet. I'll start a new thread for that issue.
