original 3-star review:seems to work well in all respects apart from the touch function. yes, i removed the protective film and, yes, both 5v inputs are powered.i have email'd the mfg - resolution pends...UPDATE: Sun Jan 19 16:19:33 EST 2020OK... it works. my bad - connection issue. on receiving an email from the mfg/cust support, i was advised to "please connect to Pi3B+ as the attached manual".tl;dri'm using an R Pi 3B+ with OpenAuto running on Raspbian and i intend to mount it in an '04 ford ranger.the "quick start guide" is not terribly useful. less than useful, actually, and there is no other documentation.the display is bright, crisp and clear, and the touch function works quite well. read on for full disclosure.the unabridged version:as mentioned, the enclosed directions aren't all that great. under the 3 line paragraph marked "to use it as a touch screen for the R Pi, you may need:". here, it shows a picture of the enclosed FPC cable with the caption, "an fpc cable, to connect your R Pi to this touch screen". in their defense, there is another pic of a Pi (only) with 3 cables attached, with a caption, "to use it as a standard monitor..." wherein it indicates 3 cables are required including a note to connect the "5V+ Touch" to "your connected device".off to youtube. i found a review of the lebula display on the first search, but is was completely useless. quite by accident, i discovered another video (https://www.youtube.com/watch?v=_HUt6tRReEQ) for the UPerfect display but it appears to be exactly the same as this touch screen.in case the link is redacted, the video may be found at the standard youtube url with the id "v=_HUt6tRReEQ".unfortunately for most readers here, it's in german, but it is visually very clear and the german-impaired (myself included) may simply view a few spots in the video for the complete info: connection of rpi connections to display starts at 8:30 closeup of almost complete wiring at 9:30 complete wiring at 9:45its made by EddyD's SmartHome. Danke für das Video, EddyD.note that this video shows a connection scheme using an included cable (there are several) marked, "gift- 3pin power cable for the R Pi" and a very short micro-usb-to-usb-A cable. and, of course, the FPC cable. if you're not familiar with one or more of these, watch more of the video.eureka.size info - useful if you have a place in mind to mount it:actual screen dimensions (excluding mounting tabs): 4.2 x 6.5 inches, diagonally: 7.7overall dimension: 6.5 x 4.754 mounting tabs which extend the height by 0.375 each.thickness with R Pi attached: ~1.25"the indicated resolution is 1024 x 600 but the description on the amazon page says it supports 1280 x 1024. there is no mention of this in the quick start guide.it comes with a 5v 3a power brick (approx 2" x 1.6" x 1") which may be a switching PS as it does not get very warm, at least after approx 30 min use.under actual operation it uses approx 0.9a at 5.1v (approx 4 and a half watts). it did hit 1.2a very briefly during boot. my Pi displayed the "lightning bolt" using the above described connection arrangement - it may require it's own power supply.the warranty (as advertised on the QSG):30 day return60 day replacement12 mo warranty24 hr cust svc via emaillife-time after sale servicesummary and conclusions:i've had the display power'd up for only an hour or so, so i can't speak to reliability, but it behaves as advertised - bright, clear, responsive, apparently well built. there are several cables which are included eg., hdmi-hdmi, usb-micro-usb, FPC. there are adjustments for brightness, contrast, color temp, etc.i have no idea if the power brick will behave above 1 amp, but it behaved well for my purposes. i will be powering it using the DROK 90483 8A 100W DC Car Power Supply (amazon page https://smile.amazon.com/gp/product/B00C4QVTNU/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1).unless i have issues in the near future, i plan to purchase at least 2 more units.the pic is a capture from the vid - hope you don't mind EddyD. :-)
