Problems with HDMI signal

I used to connect my macbook pro 13" 10.7.3 to my LCD TV by minidisplay port to HDMI, it worked since december 2011 until yesterday. Now it does not work, my TV does not recognize the signal. How can I solve it?

If I were a betting man it probably is one of the cable components. You can try it on another TV and determine from the results if it is the cable or your TV. This of course assumes you have not made any changes in the setup when this situation occurred.
Ciao.

Problems with HDMI switching

I am having problems getting HDMI signals to come through on the receiver and TV. If the home theater system has been off for several hours, I am finding that when I use the Harmony 700 remote and select the watch TV option, the TV is displaying 'Weak or No Signal' and the receiver is displaying 'no signal.' I have to turn everything off and back on again up to six times before I can finally watch TV. I have to do the same thing if I want to watch a blu-ray movie.
When I previously had an all HDMI connection (as I do now after the Geek Squad tech changed the setup), I had this problem. I contacted my Cable company and a tech came out and informed me that beacuse of software updates on the boxes, I had to run the HDMI cable from the box direclty to the TV and then had to use red/white RCA cables for the audio. According to the cable tech, this is a standard setup among all cable companies.
I don't know what the problem is with the HDMI signal not getting to the receiver or TV from the blu-ray player, but I used to not have this issue until after the Geek Squad tech changed everything,
I'd like to identify if it's the TV or the receiver that is having problems with the HDMI switching.

The cable tech is wrong.
What kind of reciever is it? There are several recievers that have had issues with their HDMI boards that would cause this. Geek squad may just be a coincidence.

Z77-GD65, problems with video signal

Got some problem: with external graphics card (ASUS GTX660-DC2TG-2GD5) the signal disappears after a while (about 1-3 minutes) - display goes off and has floating table "No signal".
Without external card, through the integrated video - all works fine.
Has anybode had this problem?
I had a BIOS like 10.0 and then updated it to the latest version ( 10.8 ) via M-FLASH, but nothing has changed.
My system:
. MSI Z77A-GD65 (RTL) LGA1155 < Z77> 3xPCI-E+Dsub+DVI+HDMI+GbLAN+1394 SATA RAID ATX 4DDR-III
. CPU Intel Core i7-3770 BOX 3.4 ГГц / 4core / SVGA HD Graphics 4000 / 1+8Mb / 77 Wt / 5 / LGA1155
. Corsair Vengeance < CMZ8GX3M2A2133C11R> DDR-III DIMM 8Gb KIT 2*4Gb < PC3-17000>
. ASUS GTX660-DC2TG-2GD5
. Corsair TX750 < CP-9020042-EU> 750W ATX (24+2x4+4x6 / 8pin)

Yes, the forum's USB method is the safest there is. That and the reflash will ensure the ME firmware has been updated properly. Yes, you do have a safety net with the B BIOS chip.
As a side note, you shouldn't have any graphics problems when W7 is installed like some have with W8.
Edit: Problem is you need an OS installed with the forum method.
2nd edit: Recommend then to run on the onboard ports to the monitor with the discrete card removed to get the OS, drivers, reflash, etc. taken care of. Then the matter of the graphics card not working right can be addressed.
3rd edit: Has the graphics card been tested in another machine to verify it is not possibly faulty?
4th edit: Sorry about all the edits, but as I think about it, more things come to mind. Have you been connecting the discrete card with HDMI or DVI? Some compatibility issue can be a possibility with a non compliant v1.4 HDMI cable or a monitor conflict. Some Apple monitors have been known to be problematic from time to time.

Toshiba 22L1334G problems with HDMI

First of all, thanks everyone for trying to help me :)
Now let's get to the problem: i bought this Tv-Monitor yesterday and i've immediatly connected it to my PC (Video Card AMD R9 270X) with HDMI cable (The cable is rev. 1.4 and less then 1.5m).
The overall definition is very good, but i actually have 2 problems:
first, the colors are really saturated and i can't get them natural even setting the Video Card Values.
Second, the text with little font if it isn't black is very blurred and pixeled, very difficoult to read.
Searching o Google i found similiar problems for lot's of people, but they resolved the problems simply setting the HDMI as PC input.
Unfortunately they were using Samsung's or LG's displays and in my Toshiba one there isn't the setting to set the HDMI as PC signal.
What can i do to use this TV as monitor in a good way?

Hi
First of all I have to say that this Toshiba 22L1334G device isnt an PC monitor but its an TV which can be connected to the computer using the available RGB (VGA) port.
So in case you want to connect an computer to this TV and want to use it as an external monitor, you should use the available VGA port
I have to say that I had the same problems in the past with the blurred fonts using the HDMI port.
I connected had an monitor/TV combo device and connected my notebook to an external monitors HDMI port.
The blurred fonts were really a pain using office applications But I found a solution; my device supported an additional DVI port and I could connect my notebook to monitor using HDMI-to-DVI cable.
My other monitor supports from another manufacturer supports additional settings to change the font sharpness so I can use the HDMI port.

Problem with PWM signal, Please Help!

Hi all,
I am designing a PWM signal where its output is going to connect 4 optocouplers to drive a H-bridge MOSFETs. However, I am now having a problem of getting an output signal strong enough to drive the optocoupler.
I have attached the Multi-Sim file along with this post. Please feel free to help me to solve this problem thank you.
The version of Multi-Sim I am using is 10.0.144

Hi Justin,
I am slightly confused as to whether this is a problem with Multisim or the design of your circuit. Are the components in Multisim behaving in an unexpected manner in comparison to their real-world counterparts?

I bought a new MBA and are having problems with HDMI and VGA port

Hi,
I just bought a new mac book air, and at the apple stre they recommended me a mosh mini to vga cabel. I need to use my computer for projector either hdmi or regular vga adapte. The new mba only has thunderbolt, usb, memory/card slot, microphone and headphone ports.
Does anyboody has and idea how i will or how do i connect the hdmi or vga adapaters to the computer. I have been searching on the cables the apple store has available but the end that goes into the computer is not compatible with the ones I mentioned above.
Please any help would be of great help, because I dont know what to do. I think this is a problem with the new MBA.
thank you,

Thank you doubr. So what I need is to buy the thunderbolt cable and the minidisplayport to vga adapter or the griifin mini display port to hdmi tht toothpickproductions recommends, is that correct?
The one I have is a mini dvi to vga adapter and the end that goes into the computer is the same one that the minisdisplayport to vga adapter or the griffin one have, and is too big to go into the new mba. I dont know if I am confusing you more with what I am saying.
check the link below and you will see the ports the mba has
http://www.apple.com/macbookair/specs.html
if you see the ports that mba has, the two minidosplayport that are recommending do not fit..
So, do you know that if I buy the thunderboldt cable will either of the two minidisplay ports fit or I need to buy another adapter for the minidisplay ports??
thank you because I am kind of confused, I did not have this problem with the macbookpro I had before...

Problem with losing signal on my nokia e72

I noticed one problem with my nokia E72.
When i put it on table and dont touch it, it has a full strong signal. But when i am holding it in my hands, it loses signal. I know, there is an antena down the phone, so maybe it is normal. But it is annoying. Can anybody tell me his (her) experiences?
Thanks a lot :-)

Since the new E72 firmware I too experience signal drops. From full signal to nothing. Takes a couple of seconds after which the phone regains signal. Anyone else experiencing the same?

Resolution problems with HDMI

OK.
Equipment: Syncmaster 305t delivered up to 2560 resolution with the same cable when connected to Windows machine (will be relevant).
New Mac Mini with HDMI out and HDMI to DVI converter (the one apple bundles). It LOOKS like a DVI-dual (I think the pin arrangement is different according to google images).
I can't get anything more than 1280 offered to me by System Preferences.
Called apple and they suggest that I buy the Thunderbold to DVI-dual adapter. Willing to do so but skeptical.
Questions:
1) Does anyone know if the bundled HDMI to DVI in Mac Mini 2011 is a DUAL LINK DVI?
2) If it is single link, shouldnt I still be getting something better than 1280?
3) Anyone else out there using the HDMI to DVI adapter bundled with Mac Mini? Whatcha getting for resolution?
Thanks,!

Whoops sorry Zyriab - of course you are right -
I get 1280x800 offered (this is highest resolution) - Dual DVI is supposed to get me 2560x1600 (the most the monitor is capable of).
It seems I should get 1920 x 1080 even if the HDMI adapter is Single Link DVI, right?
Remember, the connectors and cable supported 2560x1600 from my PC on windows - so it isn't the monitor or the cable.
Thanks much

Problem with HDMI to mini display port

I have been using the HDMI adapter to mini-display port successfully with my TV for months. I have a late 2011 Macbook Pro. My brother borrowed the cable to use with my mom's 2013 Macbook Pro retina display and now the adapter won't work. He could not get it to work with her Macbook and had not realised that it had HDMI input so used that instead. Now he returned the adpater to me and it does not work! I am running software version OS X 10.9.2. I read about a lot of problems similar but they seem to relate to 10.8.2 software. Can anyone help or advise me why my adapter has given

I have two adapters and both have stopped working after using them with the later (2013) Mac. I think it may have damaged them in some way!

Problem with HDMI - external display resolution (MacBook andSamsung HDTV)

I just bought a new MacBook, and I have used my Samsung HDTV (http://www.amazon.com/Samsung-LN-S2338W-widescreen-720p-HDTV/dp/B000G6300U) with my old MacBook for over a year. First I tried to connect the two using the Mini Display Port to VGA adapter, which wasn't recognized by the Samsung. Now i tried using the Mini Display Port-->DVI-->HDMI route. The problem I have is that, while all the resolutions show up as able to be used in the display preferences (all the way up to 1920 x 1080), when I click on any resolution for the Samsung that is over 1280x960, all windows and dialogue boxes displayed on the samsung screen are jumpy, shaky and hazy. Is there anything I can do to allow me to use my preferred resolution of 1600x900?

I'm no expert on this, but seeing as your TV has an actual resolution of 1280x720 (according to the link), I can't see how you'd get good results from anything higher than that.

Problems with HDMI Sound (Special case)

My problem is that when I connect my Macbook Pro to the TV through HDMI the sound will only come out through the actual TV and not to the audio system that goes with it like I would like.
When I connect my boyfriends Windows laptop (in the same exact way) the problem is solved, the audio comes out through the sound sistem bar and not the crappy TV integrated speakers.
I hope I made my point clear. I can make the sound come out from the macbook but it goes to the tv and not the sound system attached bar. When my macbook is connected the audio bar switches of automatically. The tv is a Sony Bravia and the Bar is also a Sony (attached to the tv through HDMI).
Thanks and I hope you can help me!

It's likely that the laptop's attempting to output audio through the HDMI as well. Have you tried this? Right-click on the speaker icon in the notification area near the clock (in Desktop mode) and select "Playback devices." What's listed there, and what has the green check mark? Try selecting your speakers and clicking "Set Default."

P1 Problem with network signal

My p1 is losing signal when is on 2G network on 3G network signal is poor, my phon with that problem is unusable

First of all, put your SIM card in another mobile and see if there is any difference in signal strength.If it works OK in a different phone, then I would suggest a software update on your phone.

Bootcamp/Vista problems with Airport signal?

Anyone know if there are issues with the Airport drivers in Vista for the Intel Minis? I've just gotten Vista up and running this evening but I am getting terrible to nonexistant wireless signal with my Mini when booted into Vista. When in 10.5.2 though I get consistently solid, usually full bars signal.
I've hunted around in the Vista settings to see if there's a card setting that perhaps needs to be changed but I've not seen anything that seems relevant. So I am suspecting a driver issue.
Anyone got other ideas?

Craig, Welcome to the discussion area!
Compare the photos in KB 108039, Properly attaching the antenna on an AirPort Extreme Card to your PowerBook to ensure that you have properly installed the antenna wire. Proper installation takes more force than many people expect.

3.0.1 have a serious problem with 3G signal?

Hello. I've installed the 3.0.1 on my iPhone 3G S. My home is in an area usually covered by the 3G signal of TIM (Italy). After the update the 3G signal strenght is very low and the phone is always switching to Edge.
It's a shame. I want to put my iPhone back to the 3.0.

I was having this problem yesterday and today between Pleasanton and San Francisco. I've reverted back to 3.0 firmware (here's a link for the folks who are planning to do the same: http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-6582.2 0090617.LlI87/iPhone2,13.0_7A341Restore.ipsw). I just hope that 3.0.1 didn't screw up radio firmware on the iPhone such that even downgrading doesn't help. I'll report tomorrow if going back to 3.0 solves this problem for me.

IPC1100 Problems with HDMI-DVI Connection

I installed Quantum TV today and everything worked fine except for my older TV in the basement. I use an HDMI to DVI cable to the TV. The IPC1100 will only allow the 480p setting even though the TV is 720p. The previous CISCO box allowed me to set the resolution to 720p using the same set-up. Anyone else having this problem? Any ideas? Thanks.

the problem is that your b&o's dvi port don't support hdcp which is the digital copy protection widely used today
maybe b&o have some update you can apply to make it support hdcp otherwise you will never
be able to use your atv for drm material like netflix, itunes movies and the likes only free material
