Q: No Signal on HDMI TV After Lion Upgrade
-
Aug 27, 2011 12:35 AMby moorsel,Actually it is in this thread.
You could connect your mac to standard monitor over dvi ( perhaps the shop could help you out with doing this). Start terminal (explained in this thread also). Perform the mentioned commands from the prompt. Shutdown the mac and connect it to the tv and start the mac again. This worked for me.

Aug 27, 2011 6:15 AMby converting1,I have a brand new MacMini and a Insignia LCD19 Inch. I have updated to 10.7.1. I still have the same error scenario when I hook it up via HDMI cable. I get a screen with an outer space picture that looks like a shot of the milkie way. There is also an iTunes window on the side. Anyway it seems like a static shot. After about 30 seconds the screen scrambles.
I'm back to VGA.
I see many posts for Phillips. Does anyone know if those commands referenced here work for other than Phillips?
It sure seems HDMI is still an issue to me. Thanks much.

Aug 27, 2011 8:39 AMby tsotinbabai,It seems that there are still a lot of users still has problem with the new Mini and Lion AND is not fully resolved yet. There is obviously a fault in the machine(or in the Lion) and what I am surpised is that this is within the vacinity of the Apple website and the company seems not to be bothered at all about our dis-satisfaction even though we are making noises right outside their doorstep. I am a new MAC user so I might be wrong but I suspect Apple are sitting back and drinking tea and let us resolve the problem for them. This is madness to me.

Aug 27, 2011 9:19 PMby Brad Hyman,I have a Mac Mini 2010, which I have used, as media centerfor some time. I never had a problem until the Lion 10.7.1 update occurred.After this time, any time I changed resolutions, I would loose the signal to myHDTV. After the update, my Mac Mini would always boot up to 1080P and ifchanged to anything else, the signal would be lost. I also recently got a new3D TV and have verified the same problem occurs with both a Samsung and LG PlasmaTV.
I was so frustrated by this problem that I did a freshvirgin install of Lion in an attempt to fix it. I had no problems changing resolutionsat all with Lion 10.7. After updating to 10.7.1, the problem came backidentical to before.
Thing I will go back to Snow Leopard until Apple acknowledgesand fixing the problem.

Aug 27, 2011 10:02 PMby scarycall,ok... to help troubleshoot problems... please download switchresx or similar utility on a windows computer connected via hdmi to your tv and export the EDID.
I used the EDID to use this custom resolution for my Sony because the tv overscans the picture:
PowerStrip timing parameters:
1824x1018=1824,136,44,196,1018,44,5,58,148500,1
Generic timing details for 1824x1018:
HFP=136 HSW=44 HBP=196 kHz=67 VFP=44 VSW=5 VBP=58 Hz=60
VESA detailed timing details:
PClk=148500.00 H.Active=1824 H.Blank=376 H.Offset=120 HSW=44 V.Active=1018 V.Blank=107 V.Offset=44 VSW=5

My EDID is as follows... which is a Sony TV connected through a Sony Amp:

Aug 29, 2011 4:44 AMby DJRumpy,Just an FYI, the console commands are unecessary. You can enable screen sharing in Preferences. This is for those that don't like using terminal.
Open Preferences
--> Internet and Wireless
--> Sharing
Click on Screen Sharing. Add the user accounts you want to allow remote screen sharing for.
After that, as already mentioned, you can use Finder to connect to the PC, or just use it's VNC address from the finder GO menu: GO --> Connect to Server --> VNC://computername.local
Note: If you don't want to be bothered with being prompted to choose a login under lion or to bump another account off, you can just specify your credentials in the VNC command like so:
vnc://username:password@computername.local/
So in the above example if my username was widget and my password was dohickey and my Mac was call home1 then it would look like this:
vnc://widget:dohickey@home1.local/
One last thing. If you experience bugs like this you should report them to Apple. They are actually very responsive about addressing these. You'll have to create a developer ID but it's free and only takes a few seconds.
Cheers

Aug 29, 2011 11:45 AMby alexcord,Not a solution for you guys but after I was unable to re-install my Mac Mini back to Snow Leopard (due to misplacing the DVD), I bought a new TV and all is happy. I have another issue ongoing with Apple at the moment with a flickering Apple Cinema Display after my 2 year old Macbook was replaced with the latest Thunderbolt model. This has been ongoing for sometime now with no resolution (even though they manufacture both computer and display) so wouldnt hold out too much hope that this gets resolved any time soon!
Good luck though!

Aug 31, 2011 4:50 AMby joostvandersluis,I have the same problem:
New Mac Mini 2011 / OSX Lion. No picture using HDMI on Philips TV. Just the white 'start up' screen at the beginning. After that everything goes black. It does work on my JVC TV and another monitor.
One quick question;
does the problem also occur with the mini display (thunderbolt) port or is that going to work?
I'm thinking of:
Mini Display Port -> DVI -> HDMI
thanks
