Source is 1080P at 60hz from a HTPC.
Some initial findings/quirks:
1. I am getting green sparkles/noise in the picture over a ~75 foot run. However, that run is currently terminated in a patch panel in the basement and a keystone jack in the wall. (i.e., patch cable from HDMI splitter to patch panel, in-wall cat6 cable from patch panel to keystone jack in the room, patch cable from the keystone jack to the extender unit). The picture is 99% intact and watchable, but there is some clear corruption. I plan to crimp rj45 ends directly to the cable that's run in the wall (so there are no terminations other than the beginning and end points) and retest this weekend. I tested four drops in the room (this is our office, so I went a bit overboard with wiring) so I am confident it is not an issue with the particular cable.
2. I was unable to get one monitor to work when I had the receiving unit hooked up directly to the monitor via an HDMI-->DVI cable (this particular monitor supports DHCP, but does not have an HDMI port, only DVI). For some reason, when I put a monoprice 1x2 powered splitter in between the receiving unit's output and the input to the monitor (using only one output from the 1x2 powered splitter), I get a picture. This is an extremely short run for testing (~10 ft), so it is not a distance problem. This monitor works fine when the hdmi->dvi cable is connected directly to my source.
3. I previously used an HDMI detective on the output of my HTPC. I could not get a picture on any of my devices with the HDMI detective connected between the source and the HDMI splitter.
4. The picture looks perfect on two short runs, one to a 55" Samsung LED TV and the other to a 25" Asus LCD Monitor.
I plan to experiment more this weekend and will report back. It looks like I should be able to get it open fairly easily, so I'll also try to crack it open and post some pictures.
Unfortunately, I don't have a good way to test audio formats, so my testing will be limited to the 1080p video signal only.
