Question about Samsung SyncMaster 940MW 19" LCD Monitor

1 Answer

940mw - Compatibility

Hi, Fore warning...this post is fairly long so that I can give as much detail as I can Just bought a Samsung SM940MW and it works great with my xbox and dvd player, however the main reason I bought this was as a second monitor...and I can't get it to work! Upon first connection to my computer (via analog), Windows XP showed no indication that I had connected the monitor. However I installed the supplied drivers for the Samsung anyway. Still nothing. The screen on the Samsung is black with a white box floating around around the screen which reads..."Check Signal cable.PC" I tried another cable and still no luck. My computer is a Sony Vaio FS285M (laptop) running a nVIDIA Geforce Go6200 with Driver version 70.86. Sony have not released any further updates since this but I did manage to get 81.95 working, but this had no effect on the moitor so I reverted to 70.86. I have created a new profile for the Samsung using my nVIDIA settings giving it a 1440x900 res, and refresh rate of 60. Although it is 24 bit, i have tried 16 and 32....still nothing. When I first bought this monitor, I returned it for another one thinking the monitor was at fault. However, I have the same results from the replacement. I would still assume that the monitor is at fault, however, my friend tried it on his Sony Vaio (different model to mine and running an ATi card), and the Samsung worked straight away. I therefore assumed I definately have a hardware problem with my port...BUT i tried 2 different TFT displays and a CRT display in dual monitor mode and both work fine with my laptop! I am therefore at a total loss as to what to try next...I have seen the samsung working, and have seen my laptop working, just not with each other! Any suggestions before I pull all my hair out? :( Thanks

    I have the same problem. I think it is caused by incompatible voltage levels on ananog input of the monitor. When I connected the monitor to my laptop via VGA repeater it worked fine.

First thing i would check is your settings. See if windows is reconizing two monitors. If not then you will need to tell it to find it. Hook up your second monitor goto add new hardware and see if windows finds it. If it doesnt find it then i would go to manufactures site for your laptop and see if there are advanced drivers for that particular model of monitor.Also I would look at the manufacures site for advanced settings or technical information. This should solve your problem.

Need the adapter for the non standard cable connector on the back of 940mw


Your Samsung SM940MW supports multiple TV and video signal formats including NTSC, PAL, and SECAM making it multi-system.

The aerial/cable input follows the European standards. What you described as "screw on connector that has a female center" is better known as a "PAL" connector whereas the US uses the "FP". What you need then is a female FP-5 to male PAL adapter.

This page would list most of the common adapters for such a purpose. Perhaps you can print it out and show to the salesperson when you go looking for one.

Hope this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

Computer not working with Samsung LCD TV

Your PC isn't working, the "CMOS Checksum Error" is a BIOS error. It has nothing to do with the monitor.
You have to let the PC load the default settings and try to boot up, if the defaults doesn't work, you have to reconfigure the options in the SETUP program. To enter Setup press "Del" or "F2" in the POST screen.

Invalid Imaging Unit and Toners

Sorry about my last post. I didn't realize that it would be placed unter solutions. BUT I did get a resolution from Samsung. They passed me to the advanced team and they suggested I use a special code they gave me to reset all the machine. As I said before the machine was giving me an error that all the toners and the imaging unit were invalid. Samsung said to try this and if it didn't work they would send me a new (refurb) unit. They said to press in sequence <menu><#><1><9><3><start (b&w)> then when the unit cycles it will ask to imput the country, in my case I entered the US. The machine will then reset itself and all the cartridges and imaging unit should be reset to work. IT WORKED!! The machine said to wait while it re-installs the toners. When it did the red warning light turned off and the printer is working great. Hope this helps.
