Hi there,
I bought me a new Samsung 23" P2370 to give my gf my old LG 19" screen. When I rund it at its native resolution of 1920 x 1080 i have to black bars on the left and the right of my screen, like 4cm wide and the image in the middle looks (logically) squished. When I go to 1680 x 1050 the image fills the screen perfectly but is slightly blured since it's the wrong ratio and not 16x9. In the right one of the black bars there are two slightly illuminated vertical lines like one pixel wide - they are not there in the smaller resolutions.
Setup:
I have an Acer Aspire 5739G Notebook with Windows7 and a GeForce GT240M and conncected the Screen with a VGA cable since the notebook does not offer DVI. The cable, the one that came with the screen, is actually only VGA at the side of the PC, the other side is DVI (with less Pins).
What I tried yet:
- All option the monitor can offer and auto adjust
- All Windows and nVidia options that affect resolution and refreshrate
- Installed the monitor driver
- tried to play with the FN + F5 screenswitching instead of the windows one
- googled like mad and found one guy with the same problem but no solution
Things like this drive me mad since I cannot just stop thinking about it... glad about all ideas or help!

on my ati underscan was enabled by default. Maybe geforce has something similar

Yeah try to see if you can adjust underscan/overscan in your NVIDIA control panel.

No such option here. Oh and I tried to reboot since that's so obvious that I usually forget about that, still the same problem

Update: when I lock the Computer so you see the login screen on the notebook the monitor turns black. If I hit autoadjust during that time, the small pixel line disapears and if I unlock the computer again there is only one black bar left on the left and the image is less squished. But if i Hit autoadjust again while the screen is not blank, i get my two black bars again...

if your laptop offers hdmi out you could use a hdmi to dvi cable

I plugged in another laptop and it worked. So I got it down to a nVidia thing. nVidia offers an option called nVidia scaling, which should solve the issue. But this only seems to be available if you use DVI or HDMI but I use VGA on my Laptop (has no DVI). Dunno if buying a HDMI Cable and an HDMI to DVI Adapter for the Monitor could solve anything?

Have you tried setting the new monitor as primary screen?
That will make your laptop screen turn off and the computer to only use the 23" monitor.
Simply right click on your desktop and work your way in to the resolution and monitor options (not the nvidia one) and change it there.

Just wanted to let you know that I "solved" it. There was no way to do it with settings since you cannot manipulate scaling while using a VGA cable. So I bought a HDMI to DVI Cable for 10 bucks and now everything works fine. It was an nVidia driver issue in combination with the vga port.
Thank you all for your ideas.

Hi guys, I thought this was an important place to bump my concern as I just upgraded to a new video card (GTX 580) and I am getting black bars both in windowed mode in 800 x 600 resolution and in fullscreen mode. How do you fix this?! QQ its so annoying!.

To get rid of black bars: Nvidia Control Panel > Adjust Desktop Size and Position > Select "Use NVIDIA Scaling"
