Dear Team,
 
We've discovered that using large resolution PNG images (above 1024x768) pixels results in the image being scaled, manifesting as aliased pixels (jaggies) on the image.
However, when we use images less or equal to 1024x768 images are crisp and sharp.
 
Is there a maximum resolution limit on the DMP 4310 (firmware 5.2.2) before the device starts scaling the image?
 
Attached are screenshots of the same image taken from DMP 4310 versus a DMP 4400 as comparison. Notice the text in the 4310 is a lot more blurry.

Hi David,

We found out that JPG format images will be blurry on a 4310 when exceeding 1024x768 due to DMP decoding errors for JPG. However, images in PNG format are sharp without resolution limit. We have confirmed this in our Flash files. Do note however that PNG's will have more performance hit on the DMP due to extra alpha color channels and larger file size compared to a similar JPEG.

Here's a sample link to an application running on our DMP4310 using PNG's instead of JPG. You can test this URL on your 4310 to confirm.
