How to fix a pc when the monitor receives no signal?

I have a hp m9000t series, recently, I do some changes in the BIOS and after the record setting and the release of the bios computer restarts, but monitor losing signal. After many restarts still no luck still blank monitor. How can I fix my pc without monitor get a signal? BTW... I'm sure that all devices are working correctly. It is in any case to restore the setting without the bios screen?

Hello

Shut down the PC, remove the AC power supply.  Follow the procedure to clear the CMOS, which is under the heading "Compensation bios settings" to the bottom of the page on the link below.  You must make sure that you put yourself in the Earth or wear an anti-static strap to prevent damage to components on the motherboard.

  • How change the default resolution for windows to use when the monitor is not connected

    Hi, how can I set the resolution by default that windows uses when the monitor is turned off or not connected at all? My problem is that normally I use 1920 x 1080, but when I put the pc to sleep or just turn monitor and leave it like that for a while with a few app maximized, when I get back and turn the monitor on the resolution is correct but the enlarged window is resized to 1024 x 786 resolution. I tried to change in the registry DefaultSettings.XResolution a DefaultSettings.YResolution in all instances and it worked fine for a long time. Then some update that happened and now it no longer works. I reinstalled the system, but it still does not. How can I force windows to use always the 1920 x 1080?

    It seems that TMM disabling did the trick. Maximized windows are not yet moved to the left edge of the screen, well, those who have been maximized is maximized correctly as they should. I had to disable TMM through registry as I had no MMR in Task Scheduler.

    If anoyone is interested I've followed the instructions described here:

  • windows program will rearange themselves when the monitors are in mode 'sleep' - how to stop windows switching screens

    IV has 3 screens on a map via display port adapter and a 4th on a second card in order to have a 1 on top of three parameters.

    the computer itself does not sleep because I have servers running but I put screens on standby after 10 minutes.

    for a long time, all screens would go to sleep and wake up without any problems... in the course of the last months, 2 questions.

    1. once the monitors to sleep and no consistent time 1 monitor wakes up enough to show the backlight, but no display... wake up ok and sometimes screens dislocated.

    and

    2 when the monitors have the power save / standby mode, some of the Windows I had open will have been moved to different monitor as monitors have been disconnected or "detected" numbers have changed and I saw the change number several times as well, but not always.

    I say some because I have 4 windows open on my left most monitor and 2 of them end up on my right monitor after the glitch.

    Sometimes things on my low Center {main} will end up on the top of the single monitor page.

    no rhyme or reason... a few days no problem at all don't wake up and everything is where it should be and all the screens have slept through the night

  • If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore all changes since the first full file

    If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore the file with any changes made since the full backup first file...

    If the TM drive storage is full TM automatically deletes the version the oldest files for the new incremental backups can be made. Thus, in this case you cannot restore the versions that TM deleted because it takes more storage.

    Hi obafemiosinnowo,

    In version 5.5.0.2340, clicking once on your image in the toggle image size of the PIP of the size of the thumbnails to slightly larger and back. This behavior is identical to the Windows version 5.8.0.156.

    However, unlike the version of Windows in Mac version once your PIP in the largest size there is no method, by dragging the corners, etc., to resize the additional PIP. The result is that the PIP is too small, even in the larger of the two sizes available

    Hi Piya,

    I run your code, and according to your logic that it works correctly.

    It's adding that line only once because according to your logic that one line can be added to MDT, if you do not want to add line on each click on the button, follow these steps:

    selectedindex1 = chart [obj1.getSelectedIndex ()];
    selectedindex2 = shade [obj2.getSelectedIndex ()];
    selectedindex3 = rolls [obj3.getSelectedIndex ()];
    selectedindex4 = cuts [obj4.getSelectedIndex ()];

    Lbl1 LabelField = new LabelField("");
    Lbl2 LabelField = new LabelField("");
    LabelField lbl3 = new LabelField("");
    LabelField lbl4 = new LabelField("");
    If (LBL1. GetText(). Equals("") | LBL2. GetText(). Equals("") | lbl3. GetText(). Equals("") | lbl4. GetText(). Equals(""))
    {
    LBL1. SetText (selectedindex1);
    LBL2. SetText (selectedindex2);

  • How can I change the video display Mode when the monitor mode not supported?

    While creating my new monitor, I changed the computer video display mode at 120 Hz by accident.  Now I see something on the monitor other than the words not taken in CHARGE the MODE.

    My system is a new HP Pavilion p7-1423W running Windows 8.1 with Intel i5-2320 3 ghz

    I tried the start mode by pressing ESC on power but do not help the startup options.  And the just F11 menu option makes the startup screen disapear and puts the monitor mode not supported.  Tapping F8 doen't work and tapping F12 just puts me in the bios menus that do not help.

    How can I upgrade the video card integrated with a video mode that is supported when I can't see the screen?

    I answer my own question because I found my solution, thanks to my grandson (freshman to Renselear Politech).

    I shoot to buy a monitor that displays a refresh rate of 120, so I could put my rear view.

    Here is the solution.

    My computer double exit DVI.  My grandson told me to connect my new monitor to the other output because the output does not get touched when I changed the original mode of production.  He has worked and is automatically selects the default monitors mode.  Then I've reconfigured the original output using the integrated display software. Solved!

    Although everything else about my internet connection worked perfectly well, I suspected that maybe this question was related to the other oddities that I experience with my Comcast DOCSIS modem. I restarted the modem and without timeouts more in Thunderbird. Again, I didn't have no other question similar with connectivity, but my IMAP authentication uses port 993, and there was something stuck on the subject through my connection. Maybe this info will help some people to solve the problems they are the way out of this problem.
