Every time I attempt to input that refresh, the display seems to show only every other frame, or at 37.5 FPS. In the Blur Busters Test UFO tool I posted above, the 38 Hz and the 75 Hz UFO scrolls look identical.

They shouldn't look identical. If the display was only showing every other frame, there would be gaps between each square at 75 Hz, while 37.5/38 Hz would have no gaps. If either the frame rate or the refresh rate reported on the test doesn't match the actual refresh rate, then that's a performance issue with the test, not the monitor. If the frame rate and refresh rate both report 75 FPS/Hz but there are gaps between the squares, then that's the display skipping frames, but laptop screens usually don't skip frames.

I've replaced my 90 Hz slot with 75 Hz and it's now working properly and smoothly. So, it seems as if I currently have 4 working "detailed resolution" slots, but none of the "extension" slots work. Is there any way to get more "detailed resolution" slots, or fix the issue with the "extensions" so that they behave similarly?

I've never heard of this happening. There should be nothing different about the detailed resolutions in the extension block. If the added refresh rate is listed in the Windows display settings, then the resolution was added correctly. There's no way to add a resolution with the wrong frame rate. Maybe the refresh rate is not taking effect correctly after restarting the driver. Try rebooting instead of running restart.exe.
