It sounds like there is no signal to the monitor. The computer you have, does it work if you hook up another monitor? Have you taken this monitor to maybe a friends house or neighbor? See if it works. If it does; there may be a problem with your computer's video. If the monitor does not work; the issue is the monitor. It will then need to be replaced.

lead most likey or graphics card, you may have to exchange the monitor. If you can try another monitor with your pc just to prove where the fault lies

Try to wiggle the cable and see if it goes away. Seems like a loose connection somewhere. Try to factory reset the monitor from the menu.

Did you install the monitor driver? It sounds like you did not. 75Hz refresh is high, try reducing it to 60Hz at least long enough to get your settings fixed.

Hi there ,
It seems that you have a vertical section problem ,It might be possible some capacitor might have gone wrong

my moniter was automatic restarted, and osd lock not open,where is is osd open option?

You will need to change the display settings for the type of lcd monitor you have, it is a wide screen I am assuming, you can change this by right clicking on the desktop select properties then settings the screen resolution should be on the middle left side and change this until you get a screen that you like There is also an advanced setting then select monitor at the top tab and change to refresh rate to the lowest setting (60 hz) this should get the HCL monitor up then change the setting until they dont work the operating system will revert to the previous settings if you cant see anything after a change. you may also need to use the automated setup on the lcd monitor select auto from the menu (osd). Now if you can not do this on the HCL lcd you may need to use that other Samsung monitor and then set up on that at the lowest resolution so that the lcd can be changed with a working screen. Lastly you may need to uninstall the samsung monitor drivers if you installed those, and leave the generic drivers in for the monitor (plug and play monitor).
I am making some guesses here as you did not tell me if the 1st Samsung monitor was a lcd also , and if the second HCL monitor is a wide screen etc what type of operating system are you running is also important 98 is fussy and 2000 is much more simplified as is XP , vista would be garbage (if you could get it to run on a pIII),
As for reasons for resolution problems, way too many variables to discuss in a short answer forum like this, sufficed to say that the resolution is different because in the past there were lower resolution (less pixels) on monitors, the refresh rates were different by manufacturers and the way the lines were scanned could be different, so setup of the monitor with the video card was also very important interlacing etc was also handled differently until that industry decided on a common standard.
I hope this helps you to get the monitor up and running.
