I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

I have an HP Pavilion 550-154na desktop connected to my Dell monitor by HDMI cable from the graphics card, it works fine. But I'd like to connect a second monitor (or projector). The graphics card only has one HDMI port, but the back of the machine has two HDMI ports (covered with black caps), which presumably come off the motherboard. I tried plugging my monitor into one of these ports but the screen stayed blank. What are my options? Is it possible to get output from these ports or do I need to use a splitter or something?

A:Should my motherboard HDMI output ports work?

Hi: When your model has a discrete (add-on) video card, the onboard graphics is automatically disabled. Look under the Integrated Graphics specs. http://support.hp.com/us-en/product/HP-Pavilion-550-100-Desktop-PC-series/8499648/model/9242957/docu... You can get output from those ports if you remove the graphics card. If you leave the graphics card in, you can either hook up a DVI cable from the DVI out port on the graphics card to the DVI input of your monitor.  I would think most monitors have multiple inputs. If your other monitor only has a HDMI input, get a DVI to HDMI cable. You will not get audio from a DVI port.

Hi,

I have a 6 month old Z30-A Portege i7 laptop (PT243A-0HW02X) running Windows 7 64bit, and the 13.3" 1920x1080 internal display screen is not working - nothing is displayed on the screen.

However I can connect an external monitor via the RGB cable port or to the HDMI port and still use the laptop that way.

I have tried various Function F5 Output toggles choosing Clone, External, Extend, Switch Display, but nothing works to get output back again to the laptop display screen.

On the External option I see a laptop icon in grey colour with a X on the screen, and a '1' on the other display icon, and a window appears for 'Toshiba Flash Cards' with red x error message " Failed to initialize Output Configuration dialog!".

There is no further help available to tell me what the problem is.
When I choose the Function F5 Output Configuration option, the 'Internal' line is greyed out, so I can't select it.

Has anyone else had this issue?
Could a BIOS update help to tell me if there is a hardware issue?
There is nothing about the display error in the Windows event viewer.

Thanks.

A:No display on Portege Z30-A screen but HDMI / RGB ports work

I have a similar problem.

When I boot up, I see the Windows 7 logo, but then everything goes black after that.

I can start the computer in safe mode and the laptop screen works no problem. In Safe Mode I can even switch to 1920x1080 resolution. So the video hardware + drivers are working, just not in normal Windows mode.

Tried reinstalling video drivers but no luck.

I also wiped the computer and reinstalled Windows 7 + video drivers and still no luck...

It started happening literally out of the blue... after six months, like yourself.

I have a Z30t-A-123.

Does anybody from Toshiba respond here or are we left to our own devices?

Based on this info does it seem likely that the front ports themselves are faulty?

You might check to see if the case end of the USB cables are properly plugged into the front panel holding the headers. Some board need more than one brand of USB drivers, Renesas, NEC, etc.

I am currently doing research to figure out what my Laptop can do to support 120Hz at 1080p on an Asus VG248QE 24-Inch LED-Lit Monitor monitor. After doing some research, I've found that HDMI 1.4b, along with Display Port and DVI-D can all support 120Hz at 1080p, and with a DVI-D to HDMI 1.4b adapter, I should be able to get this.

I don't know however, what kind of HDMI port my PC has (or if they're all the same)? How can I find out whether or not the HDMI port on my laptop will support HDMI 1.4b to get the 120Hz I desire? I am currently using a customized Toshiba Qosmio X70-A.

Over the past few years I've had most all of my  M4600  or other M series HDMI port refuse to put out a signal.  I've had several company visitors bring their Dell laptops in and if they are M series laptops will not communicate with our overhead projectors via HDMI. The projector simply says NO SIGNAL.  Yet on the same projector when I connect my E5450 it will project just fine.  This happens when using a TV using HDMI as well.
In all cases it SEES the projector or TV screen as a second monitor.  I've popped open the PROJECT app and told it to MIRROR the screens.  I can see the monitor add itself to DEVICE MANAGER when plugging in the HDMI cable and see it leave when unplugging it. This happens with Windows 7 and Windows 10.
I had a an old M4600's connected it to my TV.  It worked for months on Windows 10 then suddenly would no longer put out a signal over HDMI.  Again, I can see the TV by correct name in Device Manager when it's plugged in, I tell it to MIRROR or even EXTEND the desktop and nothing happens but NO SIGNAL on the TV. I pulled out an even older M4600 one that had been offline for about a year and it worked until MS did updates.  I went through the Dell updates and Windows updates and will no longer work - NO SIGNAL.

A:Is there any possibility of using two hdmi ports from my pc

Using an addon card will almost always disable the onboard gpu. You could simply purchase a video card that has two HDMI ports. Or you could simply use the DVI port. The only difference between the HDMI port and the DVI port is that the HDMI port also supports audio. The video signal (quality) is the same as they are both a digital signal.

I see the two HDMI ports that you are talking about, and they have  the black plugs in them. Here is what I think is going on: The Intel processor has a video graphic card built-in, and these two HDMI is what you will use if  no video card is installed. But, since there is a video card installed with HDMI, DVI and PD ports, HP decided to plug those little black plastic thing there. I am sure if you pull the video card out of the computer, and plug your HDMI cable on any of those two ports, you will see video.  By doing so,  I think the limitations are clearly understandable.

A few days ago I installed a USB 3.0 card (to be precise, this one: 2-Port USB 3.0 SuperSpeed PCI-E Controller Card - Free Shipping - DealExtreme). It uses the very common NEC ?PD720200 USB 3.0 controller. I installed the required drivers for Windows 7, and the card worked fine for the first day or so. but not since. Whenever I plug in a USB 3.0 external hard drive, I get a false "This device can perform faster..." message, as if I had plugged the drive in a USB 2.0 port.

The external drive I am using is a Western Digital MyBook Essential 1130. It is definitely a USB 3.0 drive, and came with the required USB 3.0 cable. While the USB 3.0 card was working, I got full-speed transfers to the limit of the hard drive's ability, about 90-100 MB/s. Now I can only get USB 2.0 speeds (33-34 MB/s). Windows insists I have the drive plugged into a USB 2.0 port even though it is plugged directly into the USB 3.0 card.

Things I tried so far:
-rebooting and complete power cycle. No difference.
-plugging the drive into one port or the other. Also no difference.
-Looked in Device manager. No help there either. The controller is recognized as a USB 3.0 device is using the proper NEC drivers.

Other info that may be important:
-No overclocking settings in use.
-I made sure the cable was plugged in all the way. It's in as far as it can go, but the ports will still only act like USB 2.0 ports.

Confused. As you saying it works one way and not the other?

If so, (and assuming that the HDMI is the one having the issue) have you verified the resolution showing when using the HDMI and have you figured out if the DVI adapter you bought is actually the correct one for the video card (IOW _ are you using a 3rd party DVI to HDMI or the one that came with the card)?

The HDMI ports are a sound output device.  If you have something plugged in which can produce sound you should hear it there.
Try opening the Playback devices window from the speaker icon on the taskbar.  You should see the HDMI listed and showing sound levels if actual sound is playing.  If you don't, look for any other device which may be showing changes in sound levels.  You may have to disable one type if it is getting your sound.

Hi there,
I've got an OptiPlex 3040 micro running Windows 10 64bit (came installed on the machine) and two monitors (Dell U2415, came as a pair) using extended display. One monitor has an HDMI-HDMI cable going into the computer's HDMI port, the other has a DisplayPort-DisplayPort cable going into the computer's DisplayPort port. (There is no VGA port installed on this machine)
Both monitors are on the correct setting for detecting what cable is plugged into them. Whichever monitor the DisplayPort cable is plugged into cuts out to a black screen with nothing on it multiple times an hour during normal computing (mostly email and web browsing). Not a steady flicker, just randomly goes black and randomly comes back on.
I uninstalled and reinstalled the drivers for the monitors, checked all the settings, ran the troubleshooter (no issues found), updated my graphics card driver (it was already the latest version), and nothing seems to be wrong there.
When I swapped the HDMI and DP cables to see if it was a cable issue or the physical monitor, the monitor that then had the DP cable plugged into it started to have the problem, whereas the other monitor (now plugged in via HDMI) had no problems. Originally there was a Mini DP-DP cable connecting one of the monitors and I thought maybe that was the issue, so I replaced it with a brand new DP-DP cable the other day. Still having issues with whichever monitor is connected via DP.

This does not sound like a hardware failure. Did you check/test all of the Windows 10 power management options? Specifically the PCI Express- Link State Power Management setting? Or just set the Windows 10 power management to High performance and retest. Also, if the U2415s USB upstream cables are connected to the computer, be sure to disable the USB selective suspend setting.

What type of motherboard do you have and do you happen to check the specifications particularly with its onboard USB ports. Just thinking maybe you got USB 3.0 at the back and you're mouse is not compatible with it.

A friend asked me to look at his HP desktop PC for him because he said that his USB ports stopped working completely and believes it started right after a storm but he wasn't sure.

He said that he followed the advice of some other folks and tried running a repair installation of Windows as well as a system restore just in case it was a software issue and not a hardware issue. Unfortunately, he ended up botching the repair installation and after multiple attempts he ended up messing up his original Windows installation, and then actually installing a fresh copy of Windows on the recovery partition of his hard drive, esentially taking up the entire amount of available space on the recovery partition. Windows would boot, but you couldn't hardly do anything due to lack of disk space. Oh yeah, and the USB ports still didn't work.

This is the point in which he gave the PC to me. I assumed the issue was probably hardware, but I still did a little troubleshooting:

- There are 4 USB ports in the back and 3 in the front (1 up top and 2 under a slide-down panel). None were giving any response at all in Windows, but all were listed fine in the device manager. If I plugged in a USB drive with a power indicator light on it, the light would come on, but Windows would not recognize it.

- I booted to an older live Ubuntu Linux disc (6.10 I believe) to test out the ports and 3 of them functioned fine in the live Linux environment - 1 on the back, 2 on the front. I rebooted... Read more

Reinstall your motherboard drivers. That should fix it. Make sure you get the latest drivers from the manufacturer's website.
