Question about Samsung SyncMaster 913V 19" Flat Panel LCD Monitor
When I am in a Windows application, the screen is bright as normal.
When I go to a 3270 emulation application and the screen is mostly blank, it becomes very dim. If the 3270 emulation screen is mostly full of characters, then the screen is bright.
I don't understand what setting I have that is making the brightness change from screen to screen.

I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.

make sure you have the latest video driver.
Some video drivers you can configure/enhance your desktop settings.. ie. brightness, gamma, contrast..
If you're using windows, right click on your desktop, click Properties, choose the tab Settings, then click on the Advanced button. Choose your video card tab, and continue accordingly.

This is common problem observed in many monitors compaq,HP,HCL,IBM this is happens mainly in rainy season due to moisture,by this moisture monitor button circuit get rust inside and button pad remain pressed. so it shows a strip at the middle of monitor like contrast or brightness. So this is minor problem just replace the monitor display control button sensor or circuit.Temporarily you can warm up the monitor by hanging a bulb of 60 watt nearer your monitor to takeoff the moisture.(Dont hang the bulb too near to the monitor). It definitely solves your problem.
Have a Nice Day

You probably have caps failing in the power supply.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
