Hey - an update for anyone else in my situation.
I ended up downloading the current Iris drivers as a ZIP file. I then went to System and Display Adaptors where I could see only the Standard VGA Adaptor Driver.
I went to properties, went to update drivers. Then I chose manual update.
There I clicked "choose from local file" (or something to that effect) and directed it to the unzipped folder of graphics drivers where it found a file it could read. Then from the selection, i chose INTEL HD GRAPHICS FAMILLY
Big risk I know, but it installed and the computer has reloaded with no issue, the graphics are vastly improved and i can run games, any resolution etc - display score went from 1.0 to 4.8
Hope this helps someone else. I'm very glad it finally worked for me
