Hi guys.
I have some questions about MHL to HDMI bridge.
Lets me to explain what is my problem. I made custom electronic to convert HDMI to LVDS and drive LCD display which have native resolution 1024x600 pixels. I want to put image from my Samsung Galaxy SII phone to display . When I connect electronics to the PC, windows detect my display via EDID and put the image on screen. Everything works perfectly. But when I do the same thing with MHL to HDMI converter and phone I get black screen.
I read that MHL to HDMI converter support 720p to 1080p resolution. Is there a possibility to drive LCDs with smaler resolution than 720p trough this bridge.
nope, you need a scaler function somewhere in between.
Long time viewer, first time posting.
I'm a science teacher and I use a galaxy note 10.1 (original) to do my lectures and I project the image on the screen with allshare cast. The problem is, our school has old projectors with no HDMI and only XGA resolution. Up until now, I have been using an HDMI --> DVI cable which displays the image clearly. The problem of course is that there is no sound. I don't need sound most of the time, so I've been getting by without it.
However, after reading a few threads on here I found that people had success using allshare with the Cable Matters active HDMI --> VGA with audio cable on amazon. So I picked up one of those. I connected the cable and sound, made sure to power it with the usb cable, and it shows up with just a black screen. No matter what configuration it is in, it just shows a black screen. When I pull the HDMI cable out of allshare and put it into a laptop (acer chromebook), the image displays on the screen fine. So the VGA cable and adapter both work.
Allshare works on the projector with DVI, but not VGA, whereas a laptop works with both on the same projector. Any help?
Does that HDMI-VGA adapter support HDCP? I'm pretty sure there's been a change to the ASCD to require HDCP support on the "display" end.

I did see that, though I'm still on the old LJ02 firmware and furthermore the others I've heard with hdcp issues received a message saying that the device was not hdcp compatible. In my case I cant even see the allshare cast instruction screen (it's black) but I CAN see the dongle on my device and connect.
Hi Everybody,
When connecting my LG Optimus G (CM 11) to my Asus 1440×900 screen through 1) an MHL adapter 2) an HDMI cable and 3) an HDMI->DVI converter, I keep getting a 640px x 480px output regardless of the resolution set. I've already tried three of the resolution changer programs available on google play. When setting different resolutions, changes take effect on the screen of my mobile, but the image of the secondary screen is always fitted into a 640×480 "frame". Then this is stretched on the monitor.
When I connect my mobile to an HDMI-capable monitor through the MHL adapter and an HDMI cable, the phone can recognise the resolution of the monitor, and no such problems occur.
When I connect my computer to my Asus monitor through the setup described above (MHL adapter, HDMI cable, HDMI/DVI converter), resolution is fine.
Do you think this problem is software-related? Can I somehow force the MHL output to the resolution of my monitor?
Thank you for your help in advance.

Hey everyone.
I need some help with an HDMI- DVI problem on my MK808B Plus
Goal:
Connect my Android Mini-TV (MK808B Plus) to a specific PC monitor.
Problem:
Monitor has a resolution of 1440x900 and no HDMI.
Story:
I have an old monitor as described above that i want to use for a small project. This project involves an android device. I chose to go with the MK808B Plus. Knowing the connections available on the monitor, i also bought a Mini HDMI to DVI-D adapter cable. I hooked it all up and the monitor detected the input but wouldn't display an image. Just random lines sometimes and then black like it was attempting to connect.
I then hooked it up to another monitor via HDMI and it worked just fine. I then plugged it into the same monitor's DVI port using the adapter and the monitor seemed to see it, and try to display it, but to no avail.
I would like any and all help i can get with this problem. If need be i can even swap the android stick for another model as i have just purchased it.
Thanks
It is needed to use Android smarthone (Mate 8) for checking HDMI inputs and outputs (check for working in/out)
I know that is the possible to use MHL adapter as HDMI output.
There is something else solutions to check that HDMI IN and HDMI OUT are working ? For use Mate 8 as portable HDMI monitor and/or signal AV HDMI source ?
