DAEWOO monitor driver needed  

Do you actually need a driver for it?

I mean, does it work even without?

Most, if not all computer monitors come with a disk or software package when purchased. Even though they are included, they are unneeded since they are just menial settings that can be done via Nvidia Control Panel or ATI Catalyst, if you don't have either of these two, then maybe you will needed drivers. Color settings in windows can be found in Control Panel > Display > Calibrate Color, or Control Panel > Appearance and Customization > Display > Calibrate Color.

First, do you use an Nvidia or ATI graphics card?
If no to the above, do you know the model number of your monitor?

It works ... but to get best out of a monitor you should have the correct driver

Frankly, I can tell you it is untrue. Only a few of the monitors I have seen had a driver disk (most are worthless utilities that do the same as the Win 7's own control panels do as said by PwnFrnzy), and none needed it to function perfectly.

A monitor is self-contained and has its own firmware and buttons to adjust whatever can be adjusted without the need for any driver, the cables you use to connect the screen does not allow the screen to interact with the computer more than telling maker, model and native resolution anyway.

All other settings fall down to graphic card settings in the appropriate control panels as it's the graphic card that can do that.
The only relatively reliable list of drivers for Daewoo screens I found is on a third party site, here, and there is no trace of a driver for your screen.
