I have a 22 inch samsung 2253BW and a ATI Radeon 4800 HD; Windows 7 x64. I have for both of them latest drivers instaled. The native resolution for the monitor is 1680x1050 but I can't set the resolution higher than 1280x1024. The monitor is connected to PC with a DVI cable.
I have reinstaled windows, reistaled the drivers, but nothing good happened.
any sugestions?

not sure if this will help but try goin to desktop, right clicking then go to screen resultion, then go to advanced settings, then list all models and try to find the resultion with 50 or 60 hz, this is the manual way to set resultions, if its not showing up then i would try to uninstall monitor drivers and set it to plug and play monitor and try the process again, if no luck then i dont know what to suggest,

hope this helps :)

thanks DEVILVSANGE for your reply, unfortunately it didn't help. I've been reading last days tens and tens of forums but didn't find any solution for my issue.

the recommended resolution by the system is 1024x768.. but that is nonsense. the highest one I am able to set is 1280x1024
but if you ask me what happens when I change resolution then everything goes as it should be, the screen gets black then it keeps working at the new resolution.

That's not really what I asked. Go into catalyst control and set up a custom resolution of 1680x1050, what happens when you do this?

What is the frequency set at the advanced settings of the resolution page ? If you set a higher resolution than can be supported by your monitor, then your resolution will be lowered automatically.

Ex: Your monitor can support 1680 by 1050 at 60 Hz, but it can only support 1280 by 1024 at 75 Hz. If your Hz value is set at 75, you can only go up 1280 by 1024.

In catalyst there are no higher resolutions to chose than 1280x1024. This is the highest available. There are only just resolutions between 800x600 to 1280x1024

I have the value set at 60 HZ by default. I've already tried to change frequency to 75 to 60 and i didn't have the option to chose any other resolutions higher than that.

Try at your own risk -
-First go to AMD catalyst and look under Information, then Software.
-Look for the 2D Driver Path. Make a note of the Path as you'll need it later.
-Go to start menu search for RegEdit
-Open Regedit as Administrator (You must open as admin otherwise regedit will not save changes).
-Open the folder as described in the 2D driver path.
-Look for a registry file in that folder called DALNonStandardModesBCD2 click Modify then add your chosen custom resolution to the list. (1680x1050 16 80 10 50 00 00 00 60 - the last two digits denote refresh rate)
-Exit Regedit
-Reboot
-Check Windows display and Catalyst Control to see your new resolution

Are you restarting Windows after the changes ? If you don't, the changes will not take effect.

EDIT: Looking at the picture above, you haven't made the reg change correctly. Pls do it again.

Samsung says it is very easy to change resolution of your monitor !!!

EDIT: I've looked all over Samsung support but could not locate drivers for your monitor. It is said that your monitor is plug and play and no driver provided. In the beginning of your post you said that you installed drivers for both our gfx card and monitor. Where did you find your monitor's drivers ?

EDIT2: Open CCC/Click Digital Flat Panels on the left pane/Click Properties (Digital Flat Panel) -> Post the screenshot of this page.

Click Scaling Options (Digital Flat Panel) -> Post a screenshot of this page.

Click HDTV Support -> Add your monitor resolution here.
