Windows 7 – Fix AMD Catalyst Control Center Scaling Option Resetting

I ran into the same issue when first setting up my own Acer H244HQ display over HDMI on my AMD Radeon HD 6970 cards.

The image over an HDMI connection can look as good as a DVI connection, with the right settings. I don't think AMD's CCC defaults to the optimum for monitors over HDMI though.

Keep the underscan/overscan settings as you had before, so the image fills 100% of the display.

Then, try looking at the Pixel Format settings associated with your HDMI display (I forget the actual location in the program where it is but it should be there). You should see a few options for formats: YCbCr, Partial RGB, and Full RGB. YCbCr is probably currently selected as the default. This is a color format typically used for movies, which is fine on a TV, but not good for a computer monitor. Change the setting to Full RGB and click Apply. The image should look much less "washed out" and a lot nicer.

EDIT

Another thing to try, if this doesn't fix the problem, is to adjust your Cleartype settings. Click the Start orb and type "Cleartype" and hit enter, and then follow the instructions in the wizard. This should help make your text much clearer to read.

To use three monitors with AMD Eyefinity at least one of them has to use the display port (either mini or full). This table is in the wikipedia article for 5800 cards but it applies to all ATI chips:

Your notebook may not support the required disaply output (see AMD FAQ). Check with HP support but that may be the reason that it is not showing up.

Yes! AMD Eyefinity technology support is also built into many of our notebook GPUs, but it is up to the manufacturer of the notebook to equip their product with the necessary display outputs.

Notebooks that offer the outputs to activate AMD Eyefinity technology include the Alienware M17x and the HP ENVY 17. Please note that the default configurations for these notebooks may not include AMD Radeon™ graphics, so be sure to verify that you have selected an AMD solution before checkout.
