This sort of flickering is sometimes reduced by turning brightness up. You have already tried that. My guess this is a PWM led monitor and that characteristic is what is bothering you. There are monitors that do not have the PWM feature. You can safely assume they are more expensive.

check that all the cables are properly connected, if possible test the monitor on another computer.

if the problem persist when connected to another computer, the problem is in the display itself. You could try going into the menu, and resetting it to factory defaults.

if that doesn't help the problem is most likely inside the display, possibly some of the components on the powersupply are worn out. Capacitors typically, which might need to be replaced in order to get rid of the problem.

the problem can also be in the settings of the computer, but if noting has been changed recently then its unlikely.

you can also try another cable, since the display has more than one way to connect to the computer, you could try another type of cable that fits the display and your computer.

if the display is still covered by warranty, after you have checked that the problem is not being caused by the settings of the monitor or by your computer, then you might want to get in touch with your dealer to arrange service / warranty replacement.

Hope it helps.

LCD problems

Try turning the brightness all the way up to 100. That seemed to solve the problem for now. I believe neilneves is right that the power inverter is not supplying enough power, but in my case at least, by increasing the brightness the LCD is now receiving enough power to not flicker.
