Manual I am still looking for a users manual for the HP a4331d monitor. I neede to make adjustments that only a manual can tell me. Perhaps a similar model with the same number and layout of buttons will work. HELP!

Manufacturer's Website: Go to the manufacturer's website (visit the official Samsung website in this case). Click on the support section, search your monitor model by product name or model number, and download your monitor model for the user manual. User manuals usually list codes and other relevant information.
User Manuals Online: Many people post user manuals online for all types of electronic devices and peripherals. You can search for your monitor and look for the user manual at sites such as ManualsLib, ManualsOnline, or Retrevo. Most of these sites will catalog user manuals for a wide variety of devices posted online by users and are normally free to access.
Physical User Manual: If you still have the original box or packaging with your monitor, there might be a copy of the user's manual in that box or enclosed. It might be in an actual printed booklet or perhaps just some links to online resources. Check under a section entitled 'Remote Control Codes' or 'Setup Instructions'.
Contact Samsung Support: If no luck finding it to download or to help you, there is contact support available, they should know where that information is, and be able to send it to you or refer you.
With these, you should be able to find the user manual for your Samsung 32" curved screen display and enter those codes.

Perhaps this guide for a similar model will be of service.

Many blood pressures monitors operate is a very similar manner. So to find the missing manual I would suggest looking at the manual section of www.retrevo.com. If the particular manual from Siemens is not found, you could perhaps look at other manuals from other manufacturers on the same site, for clues, since in general there is a great similarity of design and operation.

Hello - I just did a search and could only find a user guide. ALL of the manuals listed were on sale with the watch.
Here's a link to the user guide as it looked very similar to other models which are current -- Ray http://www.heartratemonitor.co.uk/polar_f6f_heart_monitor.html

This page is for ACER products. Select the DISPLAY, the choose the correct model for your monitor. There select Guides and Manuals. When you get the PDF file open, look for ADJUSTING DISPLAY SETTINGS. (page 6)

This is what was one one product's manual. This is similar to what my HP monitor uses. Hope this helps.

This has to do with the settings.
Go to your user manual and look up the settings in the menu, if you don't have a manual, download one. Use google.com and input your camera and the model similar to this... " Olympus FE-170 user manual pdf ' This should get you to what you need, down load the manual and view it to see how to set the menus.
You can set all the menus to factory default or reset all, or some thing similar in the menus.

You need to know what frequency the computer is outputing. That monitor will take a wide variety of inputs. And, your application can change the output as well. You can check the two links I provided, and HP will have some recomendations, possibly pricey, but they'll work.

Some multisync monitors will display the input frequency is when it comes on. Try connecting the monitor when the application is running, and when it's just on but idle. If it has a menu screen (monitor), open that and some have the current frequency being used listed. With those two ranges, you should have a starting point.

Check the setting of the sound > volume.... Check if he volume is mute....
