For Photo Frame (displaying pictures/videos on screen) you actually would like to have something bigger, I am thinking about 11.1 or even 13.3 IPS glossy displays (I think i read somewhere that glossy are better then the matt?!
Battery is not an must, as this should be placed in Living room, would preffer to put edge-v inside that frame and don’t have much cabling arround the display.
Budged well 100/150 USD, I think that i saw some without touch for even less. Is the question does touch and portable monitor works at all with edge-v as it should…
Hmm, let me search some for you and tell you, I was in the market for one as well but then dropped my plans due to some reasons, but I still remember some, Try searching for a few large Rasberry pi HDMI display, i think waveshare has a 11 inch screen, but check if the display is a compatible resolution
there are plenty and aliexpress and other CN onlineshops have them listed. I am trying to find someone here who is using it with Edge-V and have some informations from first hand.
@Vladimir.v.v as I wrote before, I wrote this post to see if someone is already using such kind of portable monitor/displays, where to find them is already known.
What ?!? I live in India, so close to China but still I don’t get free Shipping ? this I cannot compute
of course Russia is also close to China so yeah, Why?
Seems like noone is using such big Portable Monitors? I was thinking for sometling like these, with touch screen, hope that touch would work with Khadas Edge-V nut sure how to drive it, as it have only hdmi inputs?
Sorry, I do not yet have experience with this on the Edges. I had plans to convert an old(Acer-C760) Chromebook’s display for this. Kits are available to facilitate this, an example. It has no touch, but not necessary for my project. Covid induced shipping delays put a temporary hold on that for the moment.
I would think if the display accepts HDMI and supports a resolution that the Edge supports, the display would be fine. However, on the touch, if it is USB and works like a standard USB HID, it might work, or it may have a driver requirement that is not available in firmwares.
I have looked at several of these portable touch monitors, many will need 12v power, and offer two USB C ports, one for touch and one for powering an external device at 5vdc.
HDMI cable is the only way I can see to connect to the Edge-V. However, very short HDMI cables can be found, if one could be found with a right-angle(90°), it may not be too obtrusive, but the USB cables will also be hanging out of the side.
Hope you find a solution for your project.
I had hoped Khadas would offer a larger display(8"-10"), but I don’t think that is planned.
I am in pursuit of the same thing. Compatibility should not be a problem. The khadas screen uses MIPI-DSI, others use eDP. Either should work. But we need the appropriate device tree entries for them.
First those interfaces should be defined and enabled.
Then, the display needs a definition. Backlight, timings, front porch, back porch, etc. All is doable with just the tech specs for the display and the edge.
See this one here for the 5" screen.
Most panels should use the simple panel device driver but that is not entirely clear to me.
There are, however, differences between dts with kernel 4.x and 5.x. I haven’t learned device trees well enough yet to make it work. I have tried, and will continue to learn dts until I do.
BTW, dtc is the device tree (de) /compiler. So it is possible see the dts from a running system “/proc/device-tree” or from a dtb in /boot/arch/dtbs/…
And of course compile new ones.
As you probably know, the Edge-V has other display output options. “Edge can support dual independent display over USB-C, HDMI, eDP or MIPI” Finding a larger display, appropriate cable(s) and touchscreen that would work on those, would require a lot of homework. USB-C DP may be easier, as I have seen some displays that use a single USB-C cable for display and touch. However, those probably require drivers that may or may not be available in firmware for Linux or Android.
Several users have the Edge-V with the Khadas 5" display/touchscreen, reading those threads should give you an idea about using those ports(DSI, Touch, and E-DP). May want to disregard comments related to display’s size and look more for user experience-related comments.
I would be interested to learn when you find a solution, please keep us posted.
Ok seems touch can be problem, then I need to move touch as not so important part, bigger screen and nice IPS panel ist more important, can always connect to edge-v some dongle for keyboard/mouse if needed…
it’s hard for me to say why so mate
