How do I adjust the resolution on the secondary monitor?

Question

Video

The essence of the problem:
In the mode of operation of only an additional monitor, a black frame appears or the resolution becomes not 1920, but 1600.
Details: A monitor is connected to an Acer Aspire
laptop on Windows 7 x64 with a Radeon HD 6740G2 video card (drivers, that is, catalyst from the acer website) via HDMI. Envision H2776MHAL . In the "Duplicate screens" mode on the external monitor, everything is fine, there is no frame, the resolution is 1920. In the "Display only on monitor 2" mode, either a frame of 2 centimeters or a resolution of 1600, and in the catalyst parameters, the parameters for setting the resolution for the additional monitor become not available. AMD VGA driver: 8.836.1.0000 dated 2011/06/22. I can’t install a new catalyst - at the choice of my model, it displays
AMD Mobility Radeon™ Driver Verification Tool , which doesn't help. Auto detect and install from there also fails to load the "suitable driver".
If someone faced similar, prompt, please, how to win.

Answer 1

When you connect a monitor\tel via HDMI to the Radeons, the frame appears because of the settings in the catalyst.
I don't have a catalyst handy right now, and I don't remember exactly what the setting is called, but there is a monique and a slider with a default value of 15%. put 0% there.

Answer 2

I'm afraid to upset you, but you won't do anything. You had to initially select equipment according to working permits.

Answer 3

Try the latest beta driver: http://support.amd.com/us/kbarticles/Pages/AMDCatalyst1211betadriver.aspx

Answer 4

Catalyst I'll try, but something is hard to believe, thanks for the links.

Answer 5

I found this setting myself, then I went to the mail, I saw your comment :) That's right, in the Russian version it is, respectively, “My digital panels - Scaling settings”, the parameter is 0.
When connected via VGA, everything worked immediately without additional. settings.
