Cannot Switch Back Main Display After Connecting HDMI
Jul 21, 2011
I connected my HP Pavilion dv4-2165dx to my TV via the HDMI slot, and worked perfectly. I disconnected the cable from the notebook when I was done and still got the main LCD display to work. When I restarted the system, the LCD display was gone, just a blank screen with a backlight. The system is booting correctly, I can hear the windows7 startup sounds and even type my password in and access my account. So far I know that:
1. The screen hardware is not damaged, because after some reboots and taking the battery off for an hour I could get the input back with no problem (with windows complaining about being unable to boot and suggesting me to run Startup repair), but got a black screen again after rebooting again.
2. I can connect the HDMI again and get the output on the TV screen, but no main display is detected. If I toggle between displays with fn+f4, only the external HDMI-TV display works.
3. I get no startup screen either. That is, not even the first screen from where I can access the BIOS. But if I connect the HDMI-TV from the beginning I get all that info on the TV.
4. I reinstalled the Graphics driver from HP with no change.
My guess is that somewhat I messed up the default configuration and that the system is only recognizing the external displays as default displays. I haven't been able to modify this from the Control Panel - Display Settings menu, and I don't know where in the registry this default startup options could be.

I have an xfx radeon hd 6790. I am using the hdmi port and the display port for two tvs and I am using the vga (I think its called the vga) port it sez right on the box that it supports 3 monitors. I can switch between any two that I want but I cant get all three to work at the same time. I try to use all three at the same time I get "to extend the display another display must be disabled".

Whenever I switch user accounts the computer will start the switch and then lock up with a display message that says no signal on the monitor. It happens if the computer has been running for hours or only a couple of minutes. I have to shut the PC off and leave it off for 20-30 minutes. I can then restart and enter any user account. But if I try to switch user or logoff and pick a different user the whole cycle begins anew.

On Windows XP, when I pressed Win+L from a logged in account, it always went back to the main logon screen, where I can see all my accounts.But on Windows 7, it goes to the logon screen of the actual useraccount I just left. So then I have to click on Switch User when I need to see all my accounts.

I am having trouble getting video when connecting my PC to my LG LCD TV via HDMI.When I connect the two via HDMI, the television displays "no signal" however when I go into the Intel HD Graphics utility, it recognizes my TV and shows information about it.I find this strange because, previously I have been able to connect the two without any issues.SpecsASUS K52 NotebookCore i3 350MIntel HD Graphics320 GB HDD4 GB RAM

I have a Sony laptop with hdmi output.
I keep my hdmi plugged in as a watch dvd's everynight through media center, onto my 32" tv.
The thing is, the sound taskbar used to automatically switch from hdmi to the laptop's soundcard automatically. It doesn't any more. Basically, if I turn off the hdmi mode on my tv, it used to switch from hdmi sound output to laptop's card. When I activate hdmi again, it would automatically switch to hdmi output.
I'm using the nvidia provided drivers via windows update.

i was having a problem with a usb driver i downloaded for my motorola phone. I found that out because every time i disconnected it from my laptop a blue screen would pop up and would restart my computer. This happened to me 3 times. A while ago i was playing my games perfectly with my main graphics card the Nvidia GT 555m. I was charging my phone then i disconnected the usb then the blue screen popped again and restarted my laptop. I then tried fixing the driver problem and i did. The only problem was when i tried playing my games it was running slow and i noticed that it was running on the integrated graphics card Intel R graphics HD card. I went to check under display adapters and noticed that the Dedicated graphics card Nvidia Gt 555m was not there anymore.

I have a Windows 7 Professional 32 bit operating system, which is joined to a domain at my workplace. If i open Eindows Explorer and open a network drive ( I: ), then the Windows Explorer open's it, but after a few seconds later, it jumps back to the main page. It is very annoying. I have 11 network drives, but only on two networks drives occurs this problem.

I have an LCD TV with HDMI I like to watch movies on from my laptop. It's got an ATI HD2600 card.
I had issues setting up dual screens, extended vs clone etc. I just wanted a quick an d easy plug in to watch the movie, unplug to compute again. But would always have to adjust resolution on the TV from 1650 to 1920 manually.
Best I could do was to hook up the HDMI, disable the laptop display and it would show 1920 on the TV and when I unplug the HDMI, the display would come back on and show it's 1650. This is the only way I've figured out so far that would switch to the right resolution automaically. Plugging the HDMI back in would kill the laptop monitor and show on the TV.

Lately my girlfriend has been experiencing some flickering when connecting her laptop to my TV using a VGA cable or using HDMI. I know it's not the TV or the cables, since using my laptop (and others) worked fine.I updated her display drivers. She doesn't have a dedicated graphics card -- just one of those integrated ones -- but has never had a problem before. I'm not really sure what more to do for troubleshooting

If I connect my TV and run it at 1920x1080 (As it states it is capable of) I get odd placement of the screen, for example if I look at the desktop, icons are pushed over to half the screen, and it does this with a few resolutions. Unfortunately, my TV does not have a scaling feature so I am unable to properly tell it where the edge of the screen is. It seems in some games that run at the resolution, they do not do this. (For example, BF3. It shows everything within the boundaries) but my browser, desktop, and some other games fail to do so.

I have my Iiyama prolite connected via dvi and another TV via HDMI.As soon as the HDMI is plugged in I lose the DVI display and it transfers to the HDMI. The DVI is no longer detected.Does this mean if I want a second monitor I will have to set it up through VGA?

I was on my laptop, connected to the Internet, going about as normal. My Wifi Internet went out completely and then would not reconnect. When I tried plugging directly in to our modem, it came up with error 633. It seems like one of my programs is interfering with it being able to connect. I haven't added or changed any programs recently, I've only uninstalled a few games/programs that weren't in any way related to the modem.
What programs could be the cause of error 633? Is there a list? Or is there another way to fix it? I can add more detail if needed. Well, I went out today and left my computer on while I was gone. When I came back, it was connected to the Wifi again. I've been using it for a bit, but now it's going on and off again. It's on for the moment though...

I am pretty decent with computers but not an expert. I am having a little trouble with my home theater PC display flickering. My video card is a Radeon HD 6900 and the drivers are up to date. I have the HDMI out of my PC going to an Onkyo 7.1ch HT-R590 receiver and it's output going to my LG 42" TV. My OS is Windows 7 Ultimate X64.The system used to work perfectly fine but over time the display started to flicker at random times. I tried to hook my PC directly to my TV and it works perfectly fine, so I am 100% certain the problem is in the receiver. I did a bit of research and it appears to be a problem with my receiver over heating.
Now, if I run my HDMI to my TV, I cannot use 7.1ch surround sound. (Even after playing with Audio Return Channel) If I run optical to the receiver, my video card only puts out 5.1ch surround sound for some weird reason. So I did the next obvious choice, I ran a DVI to HDMI to my TV for video and HDMI to my receiver for audio. I thought it would trick it into thinking there was two displays but this does not work, I do not get audio. was wondering if you guys knew of any utilities that would allow me to output audio on one HDMI stream and video on my DVI port. I did a lot of looking around and it looks like DMCA calls for HDMI to be encrypted and you can't separate the stream. Or would I just be better off getting a separate audio card to connect to my a/v receiver

I use my computer mainly for living room entertainment and I use my HDTV (LG LED 1080p) as my main computer screen. Everything used to work fine but I've recently started having problems with the sound. When I turn the computer on, the sound works perfectly. However, if I close the TV or change the input from my computer to anything else, and then go back to the computer, the sound is gone.I looked through the sound options in the Control panel and noticed that the sound problem comes from my TV speakers (identified as AMD HDMI output) being unplugged. This is obviously impossible because the speakers are in the TV so this must be a Windows problem. This output works perfectly when the sound is on.My TV is connected to my computer through a single HDMI cable for sound and image (ATI Radeon 5700 graphics card and ASUS M4A79XTD EVO motherboard on-board soundcard, both with latest drivers). I use Windows 7 premium home edition 64-bit and I have 4 GB of RAM. i found that either logging off from Windows or restarting the computer will bring the sound back on. Unfortunately, as soon as I turn off the TV or change the input, the sound goes off again.

When playing back two channel pcm music on my diy home theater computer, the output begins to progressively contain random static as additional tracks are played. The operating system is windows 7 64 bit. There are no issues with 5.1 audio as it is always clean.My motherboard is an Asrock H67M and my processor is an i3-2100. The computer is connected to a Yamaha receiver via an HDMI cable.Video from the i3-2100 is outstanding on my 52" Sony TV. I am using the on board Intel display audio device as this appears to be the only way to transmit digital audio output to the receiver via HDMI. The only way to get clean sound when the static becomes unbearable is to turn the computer off and reboot. I'm not sure it matters, but the computer does contain a TV card.

I have an HP Pavilion Elite HPE machine, Windows 7, Radeon HD 5700 Series graphics card, connected to an Acer monitor and HDTV. Here's details on my setup:
My Equipment | Building a Home Theater With Your Office PC
My problem is that even though my HDMI cable's plugged into my Radeon graphics card, sometimes the PC only recognizes the Acer monitor and not the receiver (that's connected to the HDMI cable and my HDTV). So I end up having to plug and unplug the HDMI cable several times (sometimes 10+) before it recognizes the HDTV/receiver connection. Is there any setting that would favor the card/PC recognizing the HDMI cable more frequently? I've heard it's a handshake issue, and that maybe using a different type of cable would work. But wondering if there's a setting I could use before switching out cables.

My old monitor has problems turning on, I can leave it on for 30hrs before it decides to display a picture, or I can manipulate it by unplugging the DVI cable from the back, but sometimes even that takes a few tries. It's off warranty and for reference it's a Samsung SyncMaster 226BW.So I bought a new monitor and I have it plugged in using HDMI, but a problem I get is that when both monitors are plugged in the HDMI has no display until it gets to Windows, so I cannot see the boot process of my PC, because my old monitor as explained above has problems turning on. Was a hindrance today when I was tinkering with my SSD and had to go to BIOS, and frankly I'd like to be able to see in case anything goes wrong, like a BSOD or Windows update etc.

I have Windows 7, Premium Home Edition. When I typed Ctrl+Alt+Delete, I used to get the Task Manager. Tabs allowed me to select some options, one of which was "processes". Maybe I clicked something that changed things, but now I only get a list of running programs (NOT processes). And I don't have any tabs to select other options,How can I get the running processes list back?
