The problem is presented in the video here;
(Please visit the site to view this video)
The monitor was operating normally and after I came back from the restroom it was like this, the video presented the picture when there is no video connection , only with power. When connecting through video connection(hdmi) the picture displays but keeps flashing and flickering.
I cannot use ocd settings, only the input source menu shows no matter which button I click. So I cannot reset it to factory settings.
Anyone knows how to resolve the issue ?
