so, i have a question: what resolution does oem htc ext microusb mhl have?

How can I check that?

when you connect it to the tv the resolution must appear in the corner.
it can be 720p, 720i, 1080p, 1080i

Ah, OK. I won't know till it actually connects, then. All I get now is "no signal".

Will know by the end of the week, hopefully.

Well, I changed back to the original kernel, and still there's no signal when connecting to the TV. A friend of mine has an HTC One X, so I'll test it on her phone when we next meet up.

If that doesn't work either, then I'll have to get another MHL adapter, but as you can tell from my really slow follow-up-ing on this, I kinda lost interest by now. :S

Could someone with working HDMI output through the MHL adapter paste the contents of their build.prop file here, please?

I'll see what I can try about checking the MHL on another device.

As for the second advice, I've tried both chargers. They seem to send power fine, but MHL doesn't work.

And as for the 3rd, yeah, I guess I could try that.

Q: can I use CWM to backup the system, change the kernel, and eventually change back using the CWM if the stock kernel doesn't work either? Or would I have to go through the process of changing the kernel again?

Thanks for all the advice!

The setup is a simple "Plug n Play" solution using the HTC AC M500 12pin MHL HDMI Adaptor, with a standard Type-A HDMI cable. No power source was required.
Make sure the TV (I used a RCA 42"HDTV) is properly configured (i.e. Source > HDMI) to receive the signal.
In terms of the reception, the output was measured at HD 1080p with awesome HD Sound.
