Question about Samsung 226BW Monitor

Problem with Samsung SyncMaster 226BW

When the picture is dark, the screen slowly fades a bit out in contrast and the screen stars buzzing very low buzzing, but I'm able to hear it. Sounds like a coil that is not 100% fastened. When the image lights up again, the summing dissapears and the contrast is back to normal. I suspect the powersupply is starting to kick of, nd I would like to hear if anyone else has had this problem. (I have tried another display... No problem)

Click the top button on the side of the monitor to open the monitor's settings. In the "Picture" Settings, scroll down to "MagicBright" and open those settings. Chances are you have it set to "Dynamic Contrast". Switch that up to any of the other settings and then it won't try to adjust the gamma based on what is on the screen.

Hope this helps, I struggled with the same problem for quite a while until I found this setting.

I have a samsung moniter itts about 2 years old lately the picture keeps going grey like a lack of contrast,I have checked monitor leads i dont lose picture. I am a novice coulde it be my pcs graphics card...


If you mean by lack of contrast, that the screen illumination is low, then you probably have a faulty backlight, i.e. one or more of the cold cathode flourescent tubes is not working. Although this may be repairable, it may be more economical to buy a new monitor. Get a quote from a TV repair shop.

I rebooted my PC and now screen is darker and my colors are off


Check the contrast (darkness/lightness) on your Samsung LCD. There's a menu button on the monitor, press that and select contrast setting from the Menu.

Brightness automatically going low when the brightness is at 100


hello, please make sure the magicbrite option is not set to "dynamic contrast" as this will change the contrast levels by itself, change the settings by pressing the down arrow touch key on the monitor, change it to any other setting, game mode is blinding on my one (when the monitor works, but thats another story!!!) good luck with samsung customer care centre 0870SAMSUNG (uk)

Syncmaster 226bw goes black


If you can still faintly see data on your screen, it will be a faulty backlight in the panel most likely.

LCD panels have fluorescent tubes in them that provide the light needed to see the data. If one of these goes faulty, the circuit that drives it will turn off ALL the backlights, giving you a black screen.
Note: a faulty circuit that drives the backlights will often give the same apparent fault.
You will need to take the monitor in for repair.

Out of focus monitor - 955DF


Edge-focus is notoriously tricky on flat-screen picture tubes. I have not found anything on adjusting the focus for this model. it seems to be a common problem, though it seems to be more of a sample-defect problem rather than a poor design; a replacement should be OK.
