the only sense kernel that im aware of that supports hdmiwin is ChopSuey v.9.2.7-hdmiwin-universal and its only in a testing phase

here is the link to it

I couldnt get chop suey to mirror with my sense roms and it made my roms really laggy and choppy. I will wait until they do some more work to it before flashing again.

 

So just because you get a black screen doesn't mean it doesn't work..Hdmwin is a pretty glitchy program. I found a sequence that I HAVE to use to get it mirroring properly, it has NEVER worked the first time.

Check out this thread... post #30 has the sequence I found to make it work. Haven't tried it on a sense 3.0 rom yet because my wife got tired of having to redo all her stuff when I switch roms, and since we have our netflix mirroring working she told me to stop messing around with her phone.

Still, give it a shot and let me know if it ends up working for you.

 

After much aggravation trying to get mirroring to work, I finally figured out it was the tv. First I flashed the updated aggressive freedom kernal v0.9, hooked it up to the L.R. tv, nada. Then I tried downloading HDMwIn and running that with the updated kernel, nada. Tried B.R. tv with and without HDMwIn, different cables, wiping cache anything I thought would help, nada. Fast forward a couple weeks, I decide to get a tv for the kitchen. Set it up plug the EVO in and boom mirroring. No HDMwIn, no wiping just hook it up and go.

edit: Also make sure HDMI cable is securely plugged in

So for anyone interested:
Vizio mod# E220MV(from Sam's)
MikG v2.52
Aggressive Freedom v.09

 

I use HDMwIn which is amazing and is very good for the not-so-advanced users. It is very simple to use and the language is very simple and easy to understand and the best part is that it is free! I believe there is a donate version too if you'd like to contribute.

I know of at least one other but I used it while it was in beta and didn't like it too much. Search for "HDMI" on the Market and see what results you get. They will be pretty self-explanatory and they should work for yours considering that the Evo is about the only phone available at the moment that has HDMI capabilities.

 

did you try any of the suggestions that redheadtarn made? check out his post: http://androidforums.com/3120560-post30.html. i could never really get hdmi out working very well myself that i gave up. no real need for me.
