HDMI disappears when the TV is off or another entry is used

I just started using a new HTPC with Vista Home Premium and a card mother Gigabyte GA-MA74GM-S2H. The TV is a large screen LCD from Sony with 3 HDMI, AV several and other inputs. If the HTPC is running and connected via HDMI to the TV, I turn on the TV to another entry or turn it off, the PC stops the HDMI output and I can't go back except by turning off the PC with the power switch, which, of course, is not closed Vista properly and is ugly. Anyone got any ideas on the parameters that could fix this problem?

Hello KumbiaKid,

Thank you for posting.  Is the HDMI connection to your PC on the motherboard or on a video card.  It seems that your problem is driver related, and is a way to refine it to see if the HDMI connection on the graphics card or motherboard.  If she a video card, then an updated driver may solve the problem.  Ati and Nvidia offer updates driver with release notes that show the difficulties and problems known to each version of the driver.

Please, try to check and let me know if I can offer more help.

  • Toshiba 32RV635D does not power off when the computer turns off

    Hello

    I inherited a Toshiba 32RV635D. I have a PVR based on linux (Mythtv) connected to the TV via HDMI, connected on a Nvidia GT610.

    With my previous TV, a Vistron LCD Panel at low prices, he would go to sleep when the put PC into hibernation and light up when the PC came back.
    This required no configuration of me, he's done right. The Toshiba TV does not work.

    With this Toshiba TV, when the POR turns off the TV turns off screen but is actually still on - power led remains lit in green.

    Same thing with the other way around - if I put the TV in standby and powered the POR, the TV does not respond and I have to manually put out of Eve.

    I updated the firmware and it has not changed anything, and I can't find anything related to power management in the menus of televisions. I even tried just pulling the HDMI cable to the back of the TV so it has no physical active entry, and yet, it does not fall to sleep.

    The Amazon page for TV mentions the power management features, and I expected from what I understand, it should behave the way she.

    I read a lot on HDMI-CEC, but to use it with my existing kit, I would need to buy an adapter USB - CEC, and which seems a little odd because my previous TV not cheap-as-chips just done this...

    Also, the different uses in linux suggests considers its sounds the right - 'xset q' running when the computer is idle tells me that "the monitor is turned off" when in fact it is not.

    Clues?

    Ricklous, it can be useful if you have a look at the url
    http://www.Toshiba-OM.NET/LCD/PDF/English/Country_Specific/RV635-323742-English-specific.PDF

    If you want to download the manual of the English edition for your model, I have not read through, but it may be useful to you.

    Either by the way, I have the model 32RL900A and find only a VCR plugged into the claims of taking SCART screen every time it turns on while the TV is set to a string of FTA (Free To Air) and then 'hands back' screen when he (PVR) goes out, and this, I discovered, is a characteristic of the system SCART.

    I don't know if this information is useful to you, but hope it helps.

  • U2715H - Windows automatically resized when the screen turns off then turn it back on

    • Windows 8.1 Pro
    • 1 single monitor connected to the PC
    • native resolution 2650 x 1440 at 60 Hz the value
    • through CDM of the monitor to the RFP the ti EVGA 750 SC (cable Dell)
    • all drivers updated on 28/12/15

    I just bought this monitor and I noticed this strange behavior. Whenever I have turn off the monitor (or it will turn off by itself), if I didn't have a maximized window, all windows (regardless of size) gets automatically resized to fit in the left upper quadrant when the screen turns back on again.  If I had something full screen, this behavior does not occur.

    I find this very annoying. This behavior happened with my previous monitor, which was only 1080 x 1200.

    I was unable to find any setting for the U2715H disable this "feature". This isn't because EasyArrange from Dell. I do not use this feature. And this always happens with Display Manager not installed.

    Is it just a 'feature' of Dell U2715H? Is responsible for Windows? Help, please.

    TIA

    There was no pilot or changes to the hardware of my first post.  BTW, my monitor is a Rev A02.

    A few days after my previous message, another question emerged.  Monitor flash intermittently ON / OFF every few seconds.  I unplugged/replugged the cable CDM - DP and that seems to fix things... until the next day.  This time, I nothing could fix the random rotation power SWITCH of the monitor.  Desperate, I decided to plug an old HDMI cable, I had to hang out.  Flashing problem has been resolved.  Not only this, using HDMI solved my original problem of auto resizing windows.

    The solution to my original problem: use an HDMI cable.  I went to the Dell CDM - DP cable and the problem has been resolved; no more windows resize automatically when the monitor turns off in sleep/towers.  I always get the native resolution at 60 Hz and there is no noticeable disadvantages to the use of the HDMI versus DP interface.  I've been using the HDMI cable for about a week and there is no other issue.

    Just for additional verification, I bought an Accell UltraAV DP - DP 1.2 cable (B142C-007 b-2), one of the few officially approved by VESA (see link below).  Using this cable does NOT my automatic window resizing problem original.  I do not use it long enough to see if they would prevent the random flashing question.

    I still don't know the exact cause of my original question.  I guess it's a driver problem with DisplayPort standard.  But if you do not need DP 1.2 functionality, I suggest that you just use your GPU HDMI output (if she has a).

  • How and when the computer turns off automatically?

    Listen to internet radio, Sys Pref > saving energy on the default setting, wake up and radio program cut.

    This is great... .buth how and when the computer turns off?  When I reopen it wifi comes back, I'm correct when she stops she also turns off wifi?

    Hello allan299,

    Thank you for using communities of Apple Support.

    According to your post, I see that you have any questions on how and when your computer shuts down, and how the WiFi on your Mac is affected. I know it's nice to be able to properly manage what happens when your computer stops and starts in mode 'sleep'. I'm happy to help you find the best resolution.

    You're right, when your computer stops completely it will turn the Wi - Fi. If you enable the wake for network access, Wi - Fi remains lit, and you can access shared resources on your computer, such as printers or iTunes shared playlists even when your computer is in "sleep". Definition of a calendar closing and start on your Mac can also be useful.

    Check out the following resources that will help the set options that control the energy use of your computer, sleep, and wake-up times for your Mac and the calendar from your Mac to turn on or turn off or go to sleep:

    OS X Yosemite: energy saver Preferences

    Hello

    My phone turned off (or without service) incoming calls do not show on my list of missed calls.

    There may be a voicemail when my phone is back, but no match no missed calls.

    Is there a setting that will show you missed calls when the phone is off?

    Debra

    iPhone 6 s

    Once you turn back on your iPhone, all calls that occurred while the iPhone was off should appear in the Missed Call list.

    If they do not:

    • If you are in your area served by your cellular operator, contact your operator.
    • If you are outside this area (roaming), you can not see the calls until the return.  You could ask your cellular operator on this subject.

  • Bluetooth freezes when the screen turns off

    Having a problem with the Bluetooth on my pre. I coupled it with a Plantronics Voyager 855. Initial pairing works very well, but after the screen on the pre turns off, the connection goes bad. When I turn the screen back on, the Bluetooth application on the phone always displays the connected headset, but it is not. If I try to play music, there is no sound, and if a call comes in, I can hear the person on the phone, and not on the helmet.

    About 30-45 seconds after the screen turns off, I hear the high tone of the headset which means that it has lost connection. I don't think that the headset is bad. It worked very well with my previous phone.

    If I have music when the screen turns off, the connection is very good. It's like, when there is no active communication between the phone and the headset, and the screen turns off, the bluetooth on the phone goes into a blocked State. I can restore the connection by turning off bluetooth on the phone and then on again. It reconnects to the helmet, until the next time the screen turns off.

    I tried this to get a better idea of the problem...

    If I remove helmet > disable bluetooth phone > turn on bluetooth on the phone > put the headset in pairing mode, it pairs fine.

    If I remove helmet > disable bluetooth phone > turn on bluetooth on the phone > turn off the screen > wait 45 sec > turn on the screen > put the headset in pairing mode, then it does not.

    Again, it is like turning off the screen causes the bluetooth of the phone hang. Given that the screen turns off fairly quickly, I basically disable bluetooth phone and back on every time I want to use it.

    Any thoughts?

    My problem is solved.  Turns out that I had a defective unit.  He traded last night, and it works fine now.  Got the yellow box this time.  First of all, we had the black cover.

    The swap was a little complicated.  I bought in a store of absolute Wireless in Garner, North Carolina.  It is a reseller of third party.  They did it to a Sprint service center to have a technician "certify" the default before they would replace it by car through the city.  And of course, the service center couldn't do the replacement, so I had to go back through the city to the point of purchase after they certified it.  Best of all, the procedure of "certification" involved explaining the problem to the technician for about a minute, she agreed with me that it was malfunctioned and his writing his employee with the ID on the back of a business card to bring back me to the first shop.  She has not yet turn the phone on itself.  She said pretty much the guy to the absolute Wireless has been a * beep * by sending me to it in the first place b/c, we could just do this by phone.  PITA BREAD.  But I suppose it is, that's what I to do not buy directly from Sprint.

  • Help: Fuze distorts the sound when the display turns off

    Hello

    Since a few days, I own my rocket. Today, I recognized the following problem:

    When the display turns off the "rocket" distorts the song. It's a bit like stuttering, it's his bad.

    When I keep the screen turned on (by clicking on the boxes or more) he playes the song of good quality.

    The EQ is set to standard.

    Has anyone experienced the same problem?

    I don't know what to do, what an individual problem of my camera (default?) or maybe a general problem? I would stay there or should I change it?

    Thanks in advance,

    This problem is fixed in the next firmware should be out in the next few days.

    TO work around it, just put the equalizer settings on the equalizer custom for anything other than 0,0,0,0,0

  • Accelerometer turns off when the screen is off

    When testing my application on a Z10 android port the accelerometer turns off when the screen is off. A partial wake lock does not turn the sensor back on. A wake dim screen lock is needed to re - turn on the detector. This behavior forces the screen to be all the time when an application requires the use of these sensors.

    An example would be a pedometer recording the steps throughout the day. In order to operate the screen must be turned on by the application that runs in the background. This will cause a fast draining of the battery and is not an acceptable solution.

    On Android, a partial wake lock is enough to keep the accelerometer running.

    I think this should be reported as a deficiency, a lot of motion carried since Android applications will be blocked by this and my app port is one of them.

    Tested on system Z10, model number STL100-3. Version of the 10.1.0.273 software

    The fix will appear in MR 10.2, 10.2.1 aka.

    I recently submitted a fix for the problem.

  • App background stops when the screen turns off

    I wrote an Android app with a Service that receives events from the LocationService and the accelerometer and always try now to wear 10 BlackBerry. Tests on a Z10 STL100-2 10.1.0.4181

    Once the unit has remained unchanged for some time, the location listener is not registered, in order to save energy, and re-recorded a trip again.

    Don't worry, this can be disabled via the visible activity. But it must continue with the last State (start/stop) after the reboot.

    I even magically figured out how to add additional permissions for the manifest of BAR: "_sys_android_autostart_service" and "run_when_backgrounded".

    But as soon as the screen turns off, my application stops working. No location or accelerometer case being received. Turn on the display again, everything back to normal.

    It is meant to be a question about the accelerometer, but I could not find in the tracker.

    So my questions are:

    -Is it possible to port Android continue to receive events location when the screen is off?

    -Is it possible to port Android continue to receive events of accelerometer when the screen is off?

    -Will my service to continue to operate if more than 8 Apps began after mine? (And the user did not hit the close button)

    -The "headless" 10.2 mode help? (I currently only test with 10.1, because my service provider has not yet unlocked 10.2)

    -Finally, this would be possible with a native application? (I could port the port iOS... lots of fun...)

    Thank you very much for your help!

    PS: If it's of any interest: I use the plugin V1.6.1 Eclipse/ADT to package and install the bar.

    As reported here as well (and I'm sure in other places)

    http://supportforums.BlackBerry.com/T5/Android-runtime-development/accelerometer-turns-off-when-Scre...

    I'm working on a deal in the next version, similar to what we're doing with location requests (in other words, activate us the background mode if your app acquires a partial wake lock).

    Edit:

    So my questions are:

    -Is it possible to port Android continue to receive events location when the screen is off?

    (Yes, but you must hold a wake lock).

    -Is it possible to port Android continue to receive events of accelerometer when the screen is off?

    (For the moment, no, but I'll change that, so it behaves like location.)  Mind you, this could be used to work on old revisions of the software until the native sensors team added a background of sensor mode which is disabled by default and must be explicitly enabled).

    -Will my service to continue to operate if more than 8 Apps began after mine? (And the user did not hit the close button)

    (There are a lot of thing that matters if your Services happens to run or not, which is not limited to, but includes the number of applications already running and the status of the device memory).

    -The "headless" 10.2 mode help? (I currently only test with 10.1, because my service provider has not yet unlocked 10.2)

    (No, it's a native thing.  Your application is already technically without head)

  • Sound and SoundChannel question when the screen is off

    Platform: AIR 3.8 on Andorid

    Classes: SoundChannel & Sound

    Background: I am writing an application that plays the songs one after another. I'm listening to the SoundChannel instance soundComplete event. When the current song is finished, it will create a new Sound object, the sound will then load a URL and play the next song. It worked fine when the application is activated.

    Question: when the application is reduced or if the screen is off, the next song will not be played. I have to switch him back to the app or turn on the screen, then the next song will be played automatically again. I don't know if it's because the of the SoundChannel object soundComplete event will not fire when the screen is off, or if it's because the Sound object doesn't start loading when the screen is off.

  • menu Spry disappears when the window browser pulled/stretched manually

    Hello

    my menu spry seems to disappear when the browser window is pulled/stretched manually expand beyond a certain point. He himself the stack when the window manually reduced to a narrower format. This is regardless of the float property, either to the right or left.

    I'm still at the stage of construction of the building/dev...

    {.menuWrapper}

    float: right;

    width: 60%;

    margin-top:-38px;

    }

    Thank you!

    There are two problems here.

    1. when the browser is an average width, any adjustments in place, no problem

    2. when the browser is reduced in width, there is not good enough real estate menu bar, so the last item of the menu, and then double to the high slot the MenuBar

    3. when the browser is expanded, the bar of menus is able to escape alongside the image of c2c_logo, but because you set a top margin-38px, the menu bar springs out of sight.

    Solution:

    1 give the menu bar more real estate to remove white space next to the actual image, which makes the smaller image or the default method, change the image to a background image. The latter will provide the best way to provide the necessary space for the menu bar.

    2. After doing the above, you will notice that the menu bar disappeared once more, the top margin should therefore be adapted. The top margin will be in the region of 120px
