The tests that people often use have a resolution test pattern like this image

, and it scrolls across the screen horizontally at fixed speed.
When it starts moving, these lines will start to blur together.
On a display which has "300 lines of motion resolution" only the lines at the 300 mark are distinct and anything below that blurs together.
On a display which has "600 lines of motion resolution" much finer details still remain sharp in motion.
Motion resolution is basically the combination of panel motion blur and persistence-based motion blur.
Even though OLEDs have almost zero panel-based motion blur, they have maximum persistence-based motion blur since they are flicker-free displays.
At the speed these tests move, any flicker-free display can only resolve 300 lines of motion resolution at most without using interpolation.
If you have a really
bad LCD, maybe the response time drops that even further to something like 250.
If you have a plasma TV, it probably scores somewhere between 600 and 1080 lines of motion resolution.
If you have an LCD with a low-persistence backlight mode which strobes/scans the LEDs, even though the panel response time is slower than the OLED panel, the perceived motion blur is lower so your motion resolution can easily score 1080 on this test.
Personally I don't actually think it's a great test.
It may be good if you want to post actual numbers while being able to do the evaluation by eye, but even displays which score 1080 on this test often don't have great motion handling.
They have better motion handling than one which score less than 1080, but the test pattern moves at such a slow speed, it doesn't tell you anything about how the display handles fast motion.
The tests were basically tuned so that it would show plasma TVs as having top scores, while putting flicker-free LCDs in a bad light. (created before interpolation and backlight scanning/strobing was common)
I still remember some of the promotional material that Panasonic put out where their previous year's "1080 lines of motion resolution" displays were downgraded to something like 900, while their new models were now scoring 1080. It confirmed the suspicions I had about the test to begin with, as they had clearly just increased the speed enough so that the new model with its improved motion handling still scored top marks, while lowering the score of the older model.
