High-DPI install results in a pixelated image

Just have a look at the image attached. We are using InstallAwareX3. Our product's artwork looks fine when screen-zoom is at 100% but it becomes pixelated when screen-zoom is set to 150%. Installaware appears to be stretching the original image to have it cover the entire dialog but the results are less than ideal. Is there anything we can do about this? I take it that it wouldn't make much sense to use higher-resolution artwork because that would mean that such artwork would get scaled down when screen-zooming is set to 100% and thus we would still have problems with certain screen-zooming-values (in this case with screen-zooming 100% instead of 150%). Feel free to correct me if I'm wrong about this.
Thanks in advance.

Dear Dominick,
this depends on the image resolution and not on InstallAware. As you see all the controls gets scaled correctly.
When screen-zoom is set to 150% not only the controls get scaled and consequently any artwork eventually present gets scaled as well ... otherwise it'll not fit the new canvas size.

First of all, thank you for the prompt response. Now as far as this issue is concerned, if we use an image with a higher-resolution it will be shown without pixelation when screen-zoom is 150% but won't it also look pixelated back at 100% screen-zoom? (given the fact that it will have to be downsized / down-sampled) In winforms the typical approach to resolve this issue is to have different sizes of an image for different screen-zoom values. But how can one apply this technique here? I can't see any options hinting towards this direction in the dialog-designer provided by IA. Is this pixelation effect something that we will have to live with? This is the core-question.

Dear Dominick,
the pixelation effect should not be so evident when the image gets down-sampled.
unfortunately there isn't a different approach that can be used.
The only suggestion is to use an image resolution that looks acceptable with the different scale factors
