Custom background image quality

Hi guys,

Anyone know why custom backgrounds appear to look horribly sharpened and compressed, even when set using the “keep original” setting? All the other options produce the same results so I’m assuming the WD is doing some processing on the image before saving it.

Is there an optimal image resolution and size that I should be adhering to?

i’m pretty sure “keep as original” pertains to the “aspect ratio” 

(ie keep original aspect … selecting fit to screen stretches the image to fit 1280x720)

for the gui interface it’s get’s scaled to 720p (1280x720) which would be the ‘optimal resolution’

videos of course will play at full hd 1080p (1920x1080)
