I have an ASUS Transformer and a ShowWX Classic Laser Projector. The laser projector comes with a VGA dock that allows you to connect it to a VGA device. I purchased an ASUS branded adapter/converter for HDMI and VGA (specifically, mini HDMI to VGA). It connects to the device fine, and the projector seems to recognize that something is there...but it says unsupported video.
This may be because the resolutions are wrong. The projector supports WVGA (848x480) resolution. I think the transformer's resolution has to be set to this, and force it out of HDMI somehow. My device is rooted.
Any advice? Thanks.

In troubleshooting this, here's the next step I'd take:
1) Instead of connecting the projector, connect to a VGA monitor. Usually, VGA monitors have a bit more range in supported resolutions. If you can get a picture on the monitor, you are on the right track. You can fiddle with the resolution to get something compatible.
One thing that's important to remember is that converting HDMI to VGA is a signal-conversion process. HDMI is digital and VGA is analog. Converting from one to the other is not a simple physical thing like using a gender-changer, coupler, or y-adapter. The signal needs to be processed and converted. There is no such thing as a passive (i.e. unpowered) signal converter. Just because you can get a physical adapter that allows you to connect one to the other is most often NOT sufficient. Some laptops that have only HDMI also put out an analog signal on some of the HDMI pins. This is to be used in conjunction with a passive HDMI -> VGA adapter. Remember that this only works because the device has been built to support a passive adapter. To my knowledge, the Prime does not fall into this category.
I have a SGS2 But my large display's resolution is only 1366*768.. but my phone output's 1920*1080 resolution through this MHL adapter. can I use this adapter+cable to my low resolution large display?
My large display - LG monitor, 1366*768, VGA and DVi port(on monitor)
tools - MHL adapter, HDMI to VGA cable
Can I do this? I hope your support.. thanks
I just purchased the official Samsung Galaxy S3 11-pin MHL to HDTV adapter from Samsung.com as a replacement for the Allshare cast dongle, because the Allshare dongle only supports 720p output.
However, when I hooked the wired MHL dongle up to my GS3 and Vizio VW42L LCD TV, it was still outputting at 720p.
So, I called Samsung mobile support and bounced around from department to department for an hour. During the call, I was told:
-It's my TV that isn't compatible. (Although my Xbox360 and cable box both output at 1080p)
-It will only display 1080p when playing back 1080p media. (I test-recorded a 1920x1080 video on the phone and playback was still at 720p)
And finally, when my request was "escalated" to their higher support level:
-The GS3 will only output 1080p video to Samsung TVs.
Um...WTF? Is that the truth?
Samsung's own site says both "HDTV Universal Adapter" and "1080p" in the specs for the 11-pin dongle. Go to Samsung's support page and search for part number EPL-3FHUBEGSTA to see for yourself.
Has anyone else been able to output 1080p video with the OEM 11-pin dongle to a non-Samsung TV?
If the "compatibility" issue for non-Samsung TVs is accurate, doesn't their page for the S3 11-pin dongle constitute false (or at the very least, misleading) advertising?
Uhm. Isn't the Vizio VW42L a 720p tv? IIRC, its resolution is 1366x768.

Nope. Like I said, I have other HDMI inputs (Xbox 360, HD cable box, and a desktop computer set at 1920x1080 resolution) that all display correctly at 1080p.
I get 1080I on my 55" sony lcd and my 24" dell monitor, but no 1080P I rather have 720P than 1080I, but i cannot change it :crying:
I wanted to connect my samsung s3 to an old viewsonic 19'' lcd monitor (VX922) which has vga and dvi-d inputs. To do this i bought following :
1. MHL adapter (which works fine i connect my S3 to my sony tv with hdmi in)
2. HDMI to VGA convertor
3. HDMI to DVI-D convertor
I have tested each individual components and they work fine. However, when connected to this monitor i do not get any display neither in the vga mode or the dvi-d mode either. Monitor too works fine otherwise but would not work with this setup for some reason. In vga mode with the mhl/vga convertor in place it simply shows a green screen but no pictures. I checked the cable with the same monitor using my laptop and that works fine. Then i tried the mhl / dvi-d convertor option but in this case my s3 continuously shows hdmi connected / hdmi disconnected and does not work either.
I have been working on finding the issue and it seems like to me that the max resolution currently supported by the monitor is the issue. Max resolution it supports is SXGA (1280x1024) and it seems that is not compatible with S3. I wanted to know if there was to lower the resolution which is coming out of the mobile? Has anyone else tried something similar outputting video to a vga or dvi port in the past?

same thing with me! I want ti connect my note 3 with my oldschool EIZO monitor via mhl-hdmi-dvi and the monitor stays on but with no picture. How can I control thr output from the pfone? Any suggestions anyone?
+1 . This one would be good to know.
Anyone happen to know if my Galaxy S2 can use MHL with a 720p screen?
My main TV reports that the signal from the MHL adapter is 1080p, but can that be changed or does the adapter auto-select a resolution? (I mean the Galaxy S2 is 480p)
I'm thinking of buying a smaller TV for my bedroom but I cant find 1080p ones (so please don't suggest me to look for 1080p one).
You can resize the screen on the tv. the MHL is up to 1080p, so it can also get lower.
I have 20" syncmaster t2000hd (16:10, 1680x1050p)
Should work good on it i guess.
