Mac Mini :: HDTV Flicker With HDMI Connected?
Feb 4, 2012
Got 2011 Mac mini and connected via HDMI to 15 months old Samsung 46 inch LED TV using 1080p and 50Hz. From start (dec 2011) I have had the problem that occationally (>50% of the times) the TV starts to flicker heavily. It is "war of the ants = cannot see anything" on the TV for like 3 seconds and then I can see the desktop clearly for around 3 seconds an then it is back to the flicker.screen. It keeps on like that until I shut-down and restart the Mac mini. Sometime restart works an sometime it does not. Anyone with similar problems that know what to do?

Mac mini, Mac OS X (10.7.2)

I also took the time to search on this topic and couldnt find anything related
heres the sitch!
Computer = Mac Mini 1.42 model
TV = Samsung TXR3079WH HDTV
DVI to HDMI cable connected to a Samsung HDTV TXR3079WH
the tv doesnt come with dvi connectors so i opted out and purchased the dvi-hdmi cable. i hook it up to the samsung tv and then boot it up and nothing appears on the screen. it just freezes the television to the point that i cant even change to a different source input.
I tested it with different resolutions (i had an LCD next to me to interchange with) and neither resolutions worked. I then thought it might be the DVI-HDMI cable so i hooked it up to my Comcast HD Box and it worked perfectly fine. I then took the Mac Mini to a neighbors house and hooked it up to his 47" Panasonic HDTV and the Mac Mini fired right up and worked beautifully on the Panasonic HDTV using the same cable. Went into System Preferences and under diplays it actually said "Panasonic HDTV" so it recognized the tv. and the resolution automatically reset itself to 1900x1200. Then afer seeing that the Mac Mini was capable of this and all the settings must have been right, i walked back over to my house and the initial problem started again. No Picture on the Samsung HDTV. After all this i found out that the DVI port on the Mac Mini works, The DVI-HDMI cable and the HDMI port on the back of my Samsung TV works as well. So i think it might just be a samsung driver issue? dont know how to resolve this issue.

i just bought the macbook alu. w/ the mini displayport, i tried to plug it directly to my samsung 1080p hdtv with the Mdport to vga cable but the tv didnt display anything. so i searched the web to find other solutions (Mdport to dvi -> dvi to hdmi cable), but for me that means buying 2 other cables so i was wondering if i could use this route: mini displayport to vga -> vga/dvi-i adapter -> dvi-i/hdmi cable -> 1080p hdtv? with this example, i would have to buy only the dvi-i/hdmi cable since I already have the vga/dvi-i adapter (my old MSI 6600gt one) so hows that sound? thx for giving me the answer ASAP cause I need to make a surprise presentation for my boy!

With my dad's MacBook pro I was able to hook it up to our HDTV using a DVI to VGA adapter, but we were never able to hook up the audio. Have any of you connected your laptops to an HDTV? If there were a video plus audio solution, that would be ideal, but I'm guessing that is not the case. So is there a cheap video adapter I can buy? My TV has HDMI, VGA, and various component inputs.

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

I bought a new HDMI adaptor for my 17" Macbook Pro. I'm plugging into a full HD compatible TV, into an HDMI port.The result is a consistant switch between the actual correct display, and colored static. The rate of the switch is dependent on the frequency of the refresh rate, but there's no way to get it anywhere near comfortable to use. I have tried changing resolutions on both sides to no avail. Here is a video of the screen periodically flickering between display and static url...Also have tried other HDMI ports and cables, all of which are known to be in working condition. Tried restarting the tv and computer. Running out of ideas and hair.Troubled Mac User

I have just tried to link my imac (2007) to my HDTV via HDMI. As mini DVI port won't carry audio I've used a separate phono to RCA stereo cable as well. Mirroring is fine but still no audio.

I've got a recent MBP with Thunderbolt. I'm trying to connect it via a Mini DisplayPort-to-HDMI adapter to an HDTV with HDMI, but the MBP doesn't seem to acknowledge the addition of the new display. What it IS doing is flickering the built-in screen occasionally, the way it does when connecting to a projector or something, but it never shows any additional displays in the displays CP, and never seems to send any signal out to the HDTV.Â
Mac: MBP 2.3 GHz i7 with OS 10.7.4
Adapter: Belkin Mini DisplayPort to HDMI
TV: Sony 32" BraviaÂ

I just replaced my HDTV with a new Sony Bravia 32EX500 (Full HD, 1080p). My previous TV (HD Ready, 720p) was linked to my 2008 iMac with a VGA cable (with a mini-DVI to VGA adapter on the Mac end). It worked perfectly fine, but I can't get it to work with the new TV. Could you please tell me what resolution, frequency, and colours I should use to make it work?
Please not that I do not want a HDMI cable. I know it'd be better and easier, but my computer is quite far away from the TV and an HDMI cable of that length would be way too expensive. I'd rather find a way to make it work with the existing VGA cable. I just need to find the right settings for that VGA input. The TV doesn't recognize the signal right now.

I will be a hardcore PC guy gone mac soon. I am getting a MAC pro in a few days.
On my PC I run a dell 30'' and a sony XBR3 at 1080P on an 8800gt. It works well.
The one thing that could ruin my mac switching plans is my TV giving me problems.
I will have an ATI and nvidia card on hand for the MAC pro.

I've seen a few posts about this problem on Macrumors and through Google searches, but I haven't found a solution to the "Black Border" problem some of us are having when connecting Macs to HDTV's via HDMI cables. Nor am I certain what the cause of the problem is: Mac?, TV?, HDMI cable length?
For me, resetting PRAM by holding Command-Option-P-R at startup and waiting for two chimes removes the black border for up to several computer restarts, but eventually the border comes back until I reset PRAM, again.
I have a 55' long HDMI cable from Monoprice ("HDMI Tin-Plated Copper CL2 Rated (For In-Wall Installation) Cable (22AWG) - 35ft (Gold Plated)") running from a Mac Pro with an ATI Radeon video card to a 52" Mitsubishi 1080p HDTV.
To clarify, this is not just a black bar at the top and bottom like when watching certain DVD's, but a black border around all four sides that effectively reduces the size of your TV from, e.g. 52" to 46" whether watching movies, surfing the web, or otherwise using the Mac via an HDTV

I need to connect my 09' Mac Mini to my Yamaha RX-V2700 receiver which outputs to my Sony XBR HDTV. I know the mini has both mini-dvi to dvi and mini-dp to dvi or hdmi available via adapters. I was thinking to go with option 1 however I was wondering what is your opinions? Is mini-display port better over mini-dvi or are they the same? Audio will be carried over optical toslink.
Option 1:
Using mini-dvi adapter to dvi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
Option 2:
Using mini-dp adapter to dvi or hdmi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.

if i buy the mini display port to dvi adapter, could i use it with a dvi to hdmi cable for my monitor. This is because the dvi and vga ports are already taken up.

I recently received a late 2007 mac mini as a hand me down from my parents and I'm trying to hook it up to a Sony HDTV via HDMI to DVI cable. I bought the cables I needed and attempted to set it up, however when I turn on the system nothing appears on the display. I've been searching posts and various forums, but haven't really made any progress because most troubleshooting guides are focused upon display problems like pixels and refreshes.
Unfortunately I don't have a VGA monitor to use (which is what the mini was previously used on) to try and see if that works.

I have a 2010 Macbook pro and I just ordered a minidisplayport to HDMI cord. I was able to get it all set up to my Sylvania 22" HDTV HERE but I can't seem to get the resolution right. I've tried multiple resolutions both via the control panel and NVidia's control panel. Keep in mind I'm running Windows 7 via bootcamp. I'm able to get the resolution to look pretty clear, but by doing so it cuts off the edges of the screen, where as if I get it so it all shows up on the screen, it doesn't look as clear.

I have an iMac 27 and I want to connect it to a HDTV samsung 46 full HD. I have conected from displayport to HDMI and i get the screen. But at the same time I have connected a 3,5 minijack from the computer to the RCA audio in of the TV but I dont get sound. I have checked the config of the TV and I dont find any place to activate it. Then, talking about the screen. I have few questions.
How can I stop the screen on the iMac and work only with the HDTV?
How can I config that the windows on the tv have bigger letters while they keep on the same way on the i Mac's screen?
The tv is kind of far away and is difficult to see the letters.

I'm using a DVI->HDMI cable to connect my Powerbook to my Sony LCD TV. The Sony's native resolution is 1366x768. For some reason my Powerbook doesn't want to switch to this resolution. I can get 1280x720, but this leaves a black border around the images the whole time.
I've tried setting a custom resolution using the trial version of SwitchResX but to no avail. It won't do it.
Anybody have any similar experiences and possibly found a fix?

I have a 27" iMac and an LG 47" 1080p HDTV. I just bought the Griffin Video Display Converter, which is certified by Apple to pass both video and audio from the mini display port on the late 2009 iMacs. Whenever somebody turns on the HDTV the iMac's screen flickers the color blue on and off, sometimes staying that way permanently. Permanently the color blue that is. The only way to get out of it is to turn the iMac off and then back on (restarting it).I have the ?Mirror Displays? checkbox checked in the ?Display Preferences?. When I uncheck that box it treats the connected HDTV as an extension to the iMac display, whether the HDTV is on or off, which makes my cursor disappear off one side of the screen. This is why I leave mirroring on.

I have a cheap hdtv. when i connect my macbook to it it doesn't get a signal (via mini dvi to hdmi) until i click "detect displays" on my laptop, then "gather windows," then when i set the display to the proper resolution (720) the image appears on my tv without a problem.
I just got a mac mini, and since i don't have two monitors I cannot use this trick. I get no image on my tv.

I currently use an LCD TV to play movies from my Macbook Pro via the MiniDVI - HDMI cable. At the moment I just connect everything up and then use the Mirror Display in the arrangement settings. So my laptop screen is the same as my LCD TV screen. What I want to be able to do though is watch the movie on the LCD TV and also use the laptop to go on the internet, is this possible?
