I can say that i have been mirroring for.months on various kernels with the ability to to do so. I have a 57" HDTV and there always has been some pixelation. Colors vary between screens also, go to Walmart and look at their TV's in electronics, they're all playing the same thing but they all have their own warmth as far as colors go. It could also depend on your video source. When I use HBO Go there is some distortion but.only during really fast action packed scenes, MLB At Bat (go Yankees!) Has some terrible looking pixelation most of the time when mirroring. I know teamwin intended on doing something about it, which I think all they were trying to do is allow the user to adjust the aspect ratio to allow for clearing viewing although in a smaller viewing area like the app they had for Froyo but they never really finished that after the kernel source code for their HDMI mirror went around to all the other kernels. It could have a lot to do with the hardware capacity of your device and even how much you got running in the devices background. Ca1ne this is an awesome kernel, you did a great job, all works well for me here!
You will never get 1080p mirroring from most devices, I think even the newer dual and quad core phones with a gig of RAM only mirror 720 and that's built in.......
Try playing with the aspect of your screen and see if you could get some better results from it
