I found out something not so cool about my iMac, they hid the screen rotation function, I figured out how to get it back, but if you restart the computer you are screwed. The screen is one third the normal size and if you can log in, you can't get to the top or bottom of the screen where all the menus are, it took me 20 minutes to figure out how to fix it. You have to boot into safe mode, then you can restart the computer and it is back to landscape mode like normal. I guess if I rotate the screen, I need to rotate it back before a power down or a restart, then I don't have to go through the hassle of safe mode. At least now I know how to fix it, I was worried I may have to go back to the computer guys again, or reload the operating system, either one would have been a pain. The reason I want to be able to use the computer in landscape is for viewing spreadsheets and other longer documents. I have a 49" curved monitor on order, so that will be for my normal landscape mode, should make everything I do a lot easier once I get things figure out. The only sucky part is that the office walls are slanted (gambrel style roof) and I can't move the monitor over as far as I would like in landscape mode, this means that the big monitor will be hanging off the desk a bit. Once it arrives and I do some test fitting, I may just be able to swap the landscape monitor to the left side and use the ultrawide one on the right side, just not sure if that will work for me, who knows, it might even be better?
I have the new mounts setup and I am about to setup the old computer so I can pull data off it, then setup quickbooks and the printer, after that I am in business, I hope.
