Mini Display- HDMI to a Samsung TV (mode not supported)

HI!
I have a weird problem connecting my 2010 Macbook Pro to a 2010 Samsung LCD TV using a minidisplay-hdmi adaptor. This used to work, and now it doesn't. The TV reports that the mode is not supported. I have tried every single resolution with no success, I have checked with alternate adaptors, alternate HDMI leads and alternate HDMI ports on the TV. All of this troubleshooting was unsuccessful.
From what I can see on the web there appear to be long running problems connecting to Samsung TVs, does anyone have a solution?
Thanks

Mac Pro to Samsung HDTV - "Mode not supported"???

Alright, so I have just received my new Mac Pro in the mail yesterday and wanted to hook it up to my television - a 1080p Samsung (Samsung LN-T4671F) HDTV. I am using a DVI-to-VGA cable. I feel I should probably explain the entire situation so that it's all clear.
The first time I started the computer after plugging it into the TV, the Apple logo with the Loading, spinning thing (not the multicolored wheel) showed in beautiful 1920x1080. After loading, the screen jumped to a lower resolution for a second and then went black, finally giving me a "Mode not supported" error. Thinking it was just a little hiccup, I restarted the computer and after the Apple logo screen, it showed me a screen on how to put batteries in my mouse (or something along those lines, I didn't really look), and then it had me set up my wireless keyboard. After this, it showed me the WELCOME video and allowed me to log on to my computer and start using it.
After about 15 minutes, I was going through the system prefs and came across display. Thinking maybe I should lower the resolution to better see text, I clicked on a lower resolution around 1600xsomething. The screen went black and gave me the "Mode not supported" error again. I thought I could just wait a few seconds and if I didn't confirm the resolution, it would go back...but it never did. After trying to restart my computer a number of times and receiving the error message each time, I booted in Safe Mode, which I am in right now.
I went into the sys prefs and made sure the resolution was set to 1920x1080, which it already was, and restarted the computer. Error again. I went into the settings of my TV and went to PC and had it auto correct the resolution to the input. Error again. I have been running in Safe Boot since - no sound is annoying - and enjoying the display in full 1920x1080 (1080p)...so the set obviously supports it (and the manual says it does too).
My video card is an NVIDIA GeForce 8800 GT. What's most annoying is that it's pretty obvious that the display supports this resolution and yet won't allow it to work outside of Safe Boot mode.
Please help

Had the same problem with an AOC 1080p TV, trying to connect to it using VGA cable.
Ivan's earlier post clued me in to solution:
- Plug in the TV, get the "Mode not supported" message on the TV
- Open the Display Preferences, you should see the display preferences for the laptop "Color LCD" monitor. Click the "Gather Displays" button - this should bring the display preferences for the TV behind the laptop preferences window. Switch to the TV's display preferences window.
- In the TV's display preferences window, switch refresh rate down to 59.9 Hertz (your TV may need different refresh rate, but on mine I only get options for 59.9 or 60).
That did it for me!

Mid 2010 Macbook Pro to a Samsung Tv. (Mode not supported)

Hi, I have a macbook pro mid 2010, when connected to an external tv, i get the mirroring option, however when i uncheck the mirroring option (cause i need 2 desktops screen instead of one), my external monitor shows " Mode not supported ". I have a samsung LCD TV. It works perfectly with mirroring option, but I don't want a mirroring option..... Can anyone help?

I have a MacBook Pro 15 inch early 2011.
The new features available in OS X Yosemite like Continuity, Handoff,etc are not supported in this model.
I did upgrade RAM to avoid any possible slowdown.
I found replacing the HD with SSD is too expensive for a 4 years old model.
Replacing the CPU/GPU is not for amateurs.
If you think that rebuilding a Mac part by part is a viable option, please go ahead and rebuild it.
Best.

When i connect my macbook using the mini hdmi to my HD samsung tv, the response is always "mode not supported". ideas?

I'm using the mini HDMI to connec to a Samsung HDTV. The response is always "Mode Not Supported." Anyone know what to do? Trying to watch TV shows from iTunes on the TV. Thanks, Hugh

Hi Jake,
It's impossible to know without troubleshooting, but it sure sounds like a bad adapter or cable.

MacBook Mini-DVI to VGA - Samsung 32" LCD - Mode Not Supported

I followed the instructions on Apple's site to use the MacBook with the lid closed and an external LCD. It worked perfectly the first time I tried it. (I believe in 1920 x 1024). It seemed a little hard to read so I changed the Display resolution, then encountered the "Mode Not Supported" on my LCD. I unhooked and used my MacBook to change the settings back, but the MacBook seems to revert to the "Mode Not Supported" resolution when I close the lid. Any suggestions? Can I reset the Display Preferences on my MacBook?

I think this procedure should work, but it requires an external USB keyboard.
- Shut down the Mac.
- Have all the following connected:
- MacBook power supply
- External display
- USB keyboard and mouse
- Open the lid on the MacBook and hit the power button.
- Immediately close the lid on the MacBook and start holding down the Shift key on the USB keyboard.
- Release the Shift key once you see the spinning gear on the gray screen on the external display.
The above procedure should cause the Mac to start in Safe mode and hopefully will finish booting into a useable screen. If that is the case, go into Displays preferences and select a known working resolution different from the one the Mac started up in under Safe mode. Now restart normally. Hopefully the newly selected resolution will persist through the normal restart and you will have a working external screen again.

"Mode not supported" freezes AppleTV Gen3 on Samsung 61in DLP. AppleTV is ok when moved to another TV... Help me get it back online with the Samsung?

I just hooked up the AppleTV Gen3, and it worked great on my 61in Samsung DLP TV that should do 1080i. When I looked at the resolution settings in the AppleTV menu, it said 720i. I tried to change the resolution in the settings menu, and it came back with a message "mode not supported..." I was able to initially get back to the menu and choose what I thought was a supported resolution (1080i), and it again displayed the same message, this time freezing the AppleTV. I could no longer communicate with the AppleTV device although the remote was working fine.
I tried most solutions that I read on the support forums. So far nothing has worked ie changing HDMI inputs, removing power, etc. I moved the AppleTV to another Samsung TV, and it worked fine - and I was able to adjust the resolution. When I returned to the orignal Samsung it again displayed the "mode not supported" menu and it remains frozen. Any solution? Will a reset back to factory settings help - or am I stuck? Frustrated. Help?

Same thing happened to me with my peruvian credit card in the peruvian app store, I want to buy an app, but it says that my credit card is "not supported in the Peruvian app store"

Apple TV - Nothing displaying "Mode not supported"

Hi,
My Apple TV arrived today. I connected it all up using a HDMI-HDMI cable. I selected the HDMI channel on my TV (Samsung LE32R74BDX) but all i am getting is "No Signal"/"Mode Not Supported". I've tried the Menu and + to change the video settings but nothing comes up. Also tried restoring to factory settings with no luck.
Does anyone have any suggestions on what i can try?
Thanks
MacBook Pro Mac OS X (10.4.9)

I had the same problem initially, different TV
though. I was about to send it back when I realized
that the message was "Mode not supported" rather than
"No signal". While the TV manual was completely
unhelpful I assumed that the TV was getting a signal,
just not one it supported.
I don't have the Apple TV manual with me but in the
troubleshooting section it give a remote combination
(I think it was menu and play) that causes the Apple
TV to cycle through all the modes it has for TV
resolution.
When I did this I did finally hit on a resolution
(720p, which obviously was not the default) that
displayed the setup screen. I was using composite
not HDMI, but this may help since it wasn't obvious
in the manual.
It's worth a try.
The key combination is 'Menu' and '+' at the same time for 5-6 seconds.
The Apple TV will then cycle through the resolutions, when you get a picture you are happy with press 'OK'

Monitor says VIDEO MODE NOT SUPPORTED after changing display settings

HELP! I am about to have a nervous breakdown with my mac mini! I hooked up the mac to my Philips LCD via DVI. No problem at all. But because the screen is only 15" I wanted to play around with the display settings a bit. So I changed the resolution from it's original 1204x768 to the one higher (not sure of numbers) and to my HORROR, I now can't get any picture at all - it says "VIDEO MODE NOT SUPPORTED". I have tried everything I can think of. I have rest the P-RAM, I have unplugged all cables, plugged the back in again, I bought the mac into work and hooked it up to my monitor and changed the resolution back to 1024x768 which is what it was on originally and that STILL didn't work. I can see the Apple logo and then it goes black and comes up with the error message. HELP! What am I doing wrong - I can't believe one click of a mouse button has rendered my display useless!!!

Welcome to Apple Discussions!
Try booting the mini without the display connected, and then, once the system is running, connect the display. This will often force the system to default to a low resolution, and then correctly detect the display when it is connected.
If that doesn't help, with the display connected, boot into safe mode (hold the shift key down when starting up) and once the system is running, change the resolution to 1024x768, and ensure the correct refresh rate is selected. Rebooting normally ought then to give you a good display.
If all else fails, boot into safe mode with the display connected, and then in the Finder's file menu, use the 'find' option to search for 'windowserver' (no quotes). You should get 2 or 3 results, including one with a string of alphanumeric characters. Move all of them to the trash and restart normally.

G5 with samsung 52" tv Mode not supported

Does anyone know how I can make my Powermac G5(single 1.8 ATI Radeon 9800pro) work with my Samsung 52 inch TV at HD resolution
I am attempting to convert my old Powermac G5 into a media computer. At some point I may want to add a blu-ray drive.
When I use the DVI on the G5 with a DVI to VGA adapter and connect to the TV via its VGA input. There is no picture and the TV says "mode not supported".
When I connect a second monitor to the ADC (via ADC to DVI) I can get the G5 to show up on the TV in mirror or extended mode (if I set the resolution to 1024 x 768 or less).
I have tried hocking up a monitor via VGA, setting the resolution to 1024x768, then shut done, restart with TV attached and still "mode not supported"
I have also tried making the TV as the main desktop in extended mode then restarting without the second monitor and still "mode not supported"
I tried a DVI to HDMI adapter but I got nothing "searching for signal" I would assume this should work so it might have been bad so I am going to exchange it and get a new one and try that.
?

I had to do the same, that is, accept a lower resolution for my LCD TV.
Using a Geforce 6800 GT, I have an interesting mix of "i" and "p" resolutions, but, as with the 9800 Pro, no 1920x1080p.
Just as well, though, as I couldn't read the text at highest resolution.
I'm pretty sure that this is simply a case of the high resolution 16:9 ratios not being supported in these older cards.
The resolutions that are available in the firmware of the cards are predominately for 16:10 ratio screens.
Remember, HDTV is a lot newer than most all AGP graphics cards.
I guess, when I have time, I'll have to play with DisplayConfigX and see if there is hope.

Mode not supported error on my mac mini help!!!

I have an 18 month old mac mini with a proview monitor.
The problem is that for the past month whenever I have restarted my mac i intermittently get a black monitor screen after the apple loading one and a monitor error message box saying 'mode not supported'. I thought it was a monitor problem, tried the auto reset button ect on it and tried ever display setting on my mac to no avail. Detecting displays in the sys prefs would also cause this problem and under my warrenty with PC world they are sending me another monitor.
If i reboot the mac by the power button on the back eventually after anything between 10 - 30 times it will all be ok. (not good for my mac or my sanity!) and only ok till i need to restart, sleep or turn off the mac.
Tonight I tried to boot from the install disk, monitor working ok this way and ran disk utility, a few permissions repaired but no other probs.
Ive firewired it to my old imac to try and see if i can change any settings but cant and the monitor is showing the firewire flashing about no probs.
So it seems its my mac thats the problem, short of a full install does anyone have any ideas?
Im just stabbing in the dark so far so could use some help
many thanks

bit of a shame as this cable/convertor was recommended on these boards by another user and was definately not cheap
I may have recommended this based on my own experience with it and the fact that it is designed for AppleTV specifically and is actually sold by Apple.
Have you contacted Kanex support to query what the issue might be?
Might be worth trying to cycle display resolutions with the remote, see black screen recovery:
http://support.apple.com/kb/ht3176
I have not used mine for a few months as I got a new HDMI equipped projector - it is not impossible that Apple have scuppered functionality with a software update though.
If you cannot get it to work can you return it to the vendor? I would not have recommended this device if Apple weren't selling it for this very purpose - even if a software update prevented protected content playback it should not stop you using Airplay of non-protected material.
My suspicion would be some kind of incompatibility when the device is working out what resolutions the projector supports. It could even be a faulty Kanex adapter.

"Mode not supported" when connecting MacBook Pro to HDTV

When I connect my MacBook Pro to the SAMSUNG widescreen HDTV and hit "Detect Displays", it does detect it as VGA Display and it gives me a bunch of options for resolutions and refresh rates, but there was no "Options" tab where I could check or uncheck "Overscan" and even keeping the refresh rate at 60 Hz, and even trying mirrored and non-mirrored screens, nothing worked. It still said "Mode not supported". I used a dual-link DVI to YPbPr cable which I just bought and my friend can connect his MacBook Pro to his HDTV with the same cable, but it doesn't seem to work for me. What's wrong?

Try using an app like to get the stranince resolution:

HT201310 what do you do when apple tv says mode not supported

My apple tv stopped working and the tv says either no signal or mode not supported. I have restarted, unplugged the HDMI cables and restarted again. I have not updated any software. This Apple tv is new since December 14. The TV I have is older Samsung HD.
Can anyone assist?
Thanks

sounds like you raised the resolution to fullhd 1080p and the samsung can't cope
To select a video mode:
Press and hold both Menu and Menu up/scroll on the Apple Remote for about 6 seconds. Apple TV will cycle through different display resolutions.
When Apple TV reaches an acceptable display resolution and "If you can see the Apple logo, select OK" appears on your TV screen, press the Play button on the Remote.

Mode Not Supported message on Sony BDPS3100 Bluray Player

Hi,
I bought a Sony - Smart Wi-Fi Built-In Blu-ray Player Model: BDPS3100 last weekend. When I play any DVDs on this player, I get a message saying 'Mode Not Supported. Please change the resolution of the external device'. I have connected this to a Samsung 1080p LED TV through HDMI cable. I get Netflix and other apps displayed properly on the TV and it works great with Wi-Fi connectivity. The only issue is that it is not playing any DVDs. I tried playing the same DVD on my laptop and it worked. So no issues with the DVD. I tried connecting the HDMI to both HDMI1 and HDMI2 ports on the TV but still no luck. I also tried chaning the Output settings in the player to reduce the resolution to 780p and 480p as well, still no luck in playing the DVD. I have not tried a Bluray disk yet. Any pointers on how to get this fixed? Oh yeah, I've tried switching off the player and turning it on but with no luck. Read somewhere that holding the STOP button for 10 secs will make the player reset the settings and play the disk but that too didn't work. So am lost at this point on how to play DVDs on this player. Any help would be appreciated.
Thanks

Do you have a laptop that has an HDMI in? Probably not, but just checking.
It may be a bad laser. Try a blu ray and see if that works
