No auto adjust for HDMI on AOC I2757Fh monitor?

Hi guys.

So I just bought myself an AOC I2757FH monitor which I originally connected via a VGA cable. However as Ubuntu has some issues with the DVI -> VGA converter I'm using for my Radeon HD 7800 I bought a DVI -> HDMI converter.

However now the auto adjust feature is disabled on the monitor, which means that the picture is completely unfocused and small in size.

Is there any solution for this issue, or do I actually need to return it to get myself a monitor with a DVI input?

Thank you.

It depends on the driver you use, but I think even the linux driver has the over-/underscan parameter that needs to be changed to get the full screen picture.

This is actually for Windows 7 64-bit. I haven't even tried running this in Linux yet, I just know from previous experience that my older 21" HP monitor had problems with the DVI -> VGA converter.

And I'm using the newest Windows Update driver, and it has recognized the monitor by name in the device manager.

Open the AMD control center, goto my digital screens and change the /over-/underscan slider. That's it. And non of your screens has problems with the dvi-to-vga converter, because there is no such converter. It's simple an adapter for the DVI-I port, that carries the analog vga signal anyway. The problem was almost sure an unsupported combination of resolution and refresh rate.

I actually thought that the DVI output did carry some digital communication to the monitor for exactly smart features. You're positive it's just a matter of analog/digital signals, and that there is no difference in the amount of data transfered?

Anyway it worked with the driver. Thank you very much for that. Any clue to why the DVI -> VGA has the option while the DVI -> HDMI does not?
