I have a Kogi l4ax monitor that I am trying to
Are you able to boot in SAFE MODE? since your monitor works on one PC, but not another, it could be your screen resolution settings in the OS on the 7000 - safe mode loads only basic windows components - and you should be able to get to the desktop and reset the resolution down to a size that suits the monitor you are using. Alternately, if you are not comfortable with uninstall tools or don't want to waste a day going into safe mode all day long to fix something which may not need attention, if you have access to a spare monitor you can try it on the 7000 and see if you get the same message at normal startup - if you don't - you can lower the resolution a tad once you get to the desktop, shut down as usual, hook the I4ax back up, reboot and see if it works. Either of these suggestions will only cost you a bit of your time - zero money and should have no negative impact on your OS or any associated hardware. This is a simple DIY deal and worth a try at least.
