LED (and all LCD monitors) monitors have a preset refresh rate of about 60Hz. Some people are sensitive to that, like yourself. The constant mild flicker can cause those symptoms. LCD monitors have a latency that nullifies that flicker, but you might be able to still pick that up.
If other LCD monitors don't give you problems it might be that the color temperature of that LED is not agreeing with you.
In CRT monitors the refresh rate is adjustable (the lower the resolution, the higher the rate can be set).
Make sure the video card refresh rate is set at the same value as the monitor's native rate. Adjust the color temp to a lower value, if possible. You can play with these settings until you find one that is OK for you.
If that happens ONLY with that particular monitor, there may be an issue with the LED circuitry that introduces a flicker; since LEDs are very low latency, any variation in the current that feeds the LED will be reflected in the intensity of light emitted, and perceived as a flicker by your eyes.
