Pegatron Chagall uses a Hannstar similar to one used in ASUS TF201 but unfortunately it is not compatible with existing simple panel setup (blurry image if used). My assumption is that chagall as different revision of this panel like HSD101PWW3-B00 or HSD101PWW1-A00 which is more likely or panel is highly modified which is unlikely. I propose to use "hannstar,hsd101pww1" which is more wide spread.
