After replacing a Fusion Drive with an SSD, it must have damaged my display. Now, there is a column of grey on the left-hand side. I double-checked the cables, and they are snug. Probably damaged beyond repair.

Is there any way to modify the Menu Bar at the top to move it right, past the grey bar, so that all the menu items are visible?

The iMac is still usable, I just use the other 2/3rd of the screen and use a lot of keyboard shortcuts. But I often can't see the menu and need to select from it.

Yes. Unfortunately, you damaged the display.

If seen this exact problem (different size and location of the bar) and it was due to a “hit” to the display along the edge of the glass.

These LCD panels are few and far between now in terms of availability. You may be able to source it used via eBay or find an iMac “for parts” that hopefully has a good LCD. Your other option would be to get a new(er) model And sell that as parts to help fund the replacement

Can you modify the display? Unfortunately no. The screen is still reporting that it’s 2560 pixels wide (EDID data). It’s hard coded into the firmware so you can’t override it to trick macOS that it’s smaller and render the display output so it “bypasses” the defective part.

  • I was checking on eBay for these panels last night. $600 + S&H. You can get a newer iMac for that amount.
