adapter HDMI / vga not detected.

I bought a Ddmi to VGA from Hp and used on my notebook to want to connect to an external projector.  He has worked for several weeks and suddenly stopped working.  The laptop cannot detect card even once. What should I do? what I've done wrong?

Hello

Thanks for posting the query on the Microsoft Community Forums. You have reached the right place. Let us work together to find the cause of this problem and try to solve.

This problem may occur if the hardware is not detected or corrupt drivers.

Method 1: I suggest you run the hardware and devices Troubleshooter and see if that helps.

b. right click the button start and select run.
c. Type Desk.cpl and press ENTER.
d. Select the second monitor and then change the resolution of great value and press on apply.
e. now, press the function keys Fn and F7 to activate the HDMI port.

  • U2717D HDMI signal not detected

    My U2717D is less than 1 week old. I plugged it with my early 2012 MacBook Pro 15 via display port using the cable supplied with the monitor. It works admirably or not the monitor input Source is set to manual or Auto select.

    Then I tried to connect my other laptops using HDMI. The cable is a HDMI cable that I connect laptops to my TV to existing work. Laptops are HP Pavilion X 2 13 (win 10 with all latest updates) and Asus S200E (Win 8.1). I also tried my MBP with a CDM-> HDMI adapter. All 3 laptops did not detect the monitor when the source is in Auto Select, monitor says HDMI no signal. All 3 laptops did not detect the monitor turned off the automatic selection and manually selected the HDMI input. DisplayPort cable has also been disconnected for the test, it made no difference. I also have a working device Google ChromeCast 2 that I plugged directly on the U2717D HDMI port. In all cases, the monitor reported no signal HDMI cable, or computers that are detectable by the monitor.

    Finally, I got the job of HP. I remember, I had to unplug all cables including the power of U2717D. Turn on U2717D, turn on the laptop, then plug an HDMI cable. A sigh of relief, I plugged the MBP to DP cable and it seems to work. The next day, I tried the Asus. Again, no signal on HDMI, no monitor detected. I unplugged DP, HDMI, pedaled power the monitor, select Manuel HDMI then connect the Asus and it finally worked.

    I have a Dell XPS13 arriving at which I intend to move the monitor between XPS 13 on HDMI and DisplayPort on the MBP (via USB to HDMI adapter type-C). However, it is unacceptable if I need power cycle and unplug the cables every time! Is a kind of 'feature' question or undocumented? Or is my defective U2717D HDMI port and I need to arrange for an Exchange?

    Before we get it exchanged, contact Dell Technical Support and ask them to send you our HDMI to HDMI Cable, part T516N. See if it fits best.

  • DELL XPS ONE 27 - no HDMI is not detected with a xbox 360. Help!

    Hi,
    
    I have a problem:
    
    I have my Xbox360 connected to a desktop computer all in one Dell XPS One 27 "with an HDMI cable and when i change the input from Computer to HDMI the monitor does not recognize the Xbox360 and get a screen black and a sign saying "No video on HDMI input detected".
    
    The issue is that my monitor has a resolution of 2560x1440 and I think the maximum resolution that gives Xbox360 is Full HD (1980x1020). But I read that the Xbox360 still have to re-scale the image until it is appropriate (ergo, leave black edges to complete the remaining pixels or, failing enlarge reducing the quality of it), right?.
    
    Anyway, I have also tried to change the resolution of my computer and neither detects Full HD HDMI (and I'm not sure that the Computer resolution remains once I make the switch to HDMI, but in principle, yes).
    
    
    
    That's it. I have asked in shops and specialists and everyone tells me that it is possible, but I do not see where it may be bad or failure.....
    
    Thanks in advance. :)
    
    PS: The cable I use is standard HDMI cable and the Xbox is FAT Xbox360.
    

    Hello.

    To resolve this problem, you will need to check that the HDMI cable is ENTIRELY in the HDMI PLUG! Believe it or not! The HDMI on the back of the OIA 2710 is a tight fit, and I thought I was going to break the taking, but he won entirely, and the xbox was on the screen.

    THE SOCKET IS A TIGHT FIT!

    MAKE SURE THAT YOUR HDMI SOCKET IS * ENTIRELY * IN.

  • Screen LCD HDMI TV not detected on Pavilion P6000

    I just bought a new LCD tv with hdmi input. My P6769uk Office, with an hdmi output, doesn't even recognize this TV/monitor, but recognized my old (now-defunct) lcd TV via hdmi. Help!

    I found a way to make things work! All that is required is that when the computer is turned on the LCD TV is disconnected from the AC power and connected to the computer via HDMI. After a minute or two, I turn on the power to the TV and BINGO, the computer can now see the TV. If the monitor has power (even in standby) the computer cannot see it when it is powered. How strange is that! At least I can use it now. The graphics card by the way is an Intel HD Graphics Family, with the version of the driver 8.15.10.2462.

  • Does not detect the hdmi cable more (very specific scenario)

    Well then...

    Got a monitor 15-HD to hdmi cable and a mac laptop (13 in the retina).

    So when I got all that I put it all together and it worked. I left because there a little bit, everything is plugged in and did not return for some time, so my mac fell asleep at the time wherever I went. Disconnected everything to relax on the couch. I went back and all plugged together again except that now the mac does not detect the cable. Tried a bunch of things with it. Restart, unplug the unit, detection manually, etc...

    Since the monitor is used and recently purchased cable, I thought time to them to test first. Got a laptop PC and plugged into the cable. The monitor and cable worked.

    Tried to connect my mac to the TV with my ps4′s hdmi since I did that a lot before. Also works.

    The problem is literally the combination between the cable and the mac. Which is a problem since I got the reason was to serve as my mac.

    During my research, I saw that specifically leaving the connected hdmi where sleeps your laptop can spoil it supposed to be... I saw it one time so idk if it's true, but it happened to me... and no, it wasn't really a solution when I came across that. Tried Googling this specific problem, but did not meet anything since my problem seems so specific.

    Fast forward to the next day and tried again now that both had little respite between them. Plugged into the HDMI and my laptop starts fading and return to a black screen. The screen would go black usually and so the laptop screen and the monitor would appear once again. sauf_que this time that there not, he just kept it and the monitor has not changed (Yes) it's). Not wanting to let him do that too long I unplugged and tried a different port with an adapter, I have also, since I did 3 holes I could use this for might as well try them all again. But unfortunately, I don't have it trigger anything again. So I went through another round of troubleshooting to try to make it work, but here I am, trying to see if anyone else has had this problem and solved. I am back to wait another day I guess and just hope. If not idk what to do, except maybe to get another cable? I don't know if this would solve it well.

  • Problems with Dell USB - C (DA200) to the HDMI, VGA, RJ45, USB3 adapter

    Hi all

    I guess I'm a little desperate at 01:45 haha...

    I just got my XPS 13 9350 and it's great. I bought the USB - C DA200 adpater USB3, RJ45, VGA, HDMI. Unfortunately, I have some difficulty with the device. They are listed below:

    (1) plug, computer does not recognize the device. If I right click and uninstall in Device Manager and do a scan 'new material', it works again - but not for long.

    (2) the device and the Realtek gigabit portion to connect and reconnect every second in Device Manager and it's annoying.

    (3) disabling the wireless card/connection really seems to help the unit to connect and it works 100%. ONLY when the wireless adapter is disconnected.

    Basically, windows is to have a real time hard keep this adapter plugged... almost as if he can't recognize it. I tried to install the drivers for the card - nothing. I've updated all the firmware from Dell crush (including the chipset) and the BIOS... nothing. Same thing. If you do a search on google, there are a few discussions on this problem. There is a nice size on Reddit.

    Someone has an idea, what happens? It's a real shame that a beautifully designed and expensive adapter does not work with a Dell computer.

    Thank you, AJ

    In another thread ("XPS 13 9350 - SSD USB C 3.1 - very unstable/not usable '-I can not add links), the following fixed my XPS 13 9550 problem using a drive HARD USB 3.0 with the Dell USB - C for HDMI/VGA/Ethernet/USB3.1 adapter:

    ... the adapter USB - C and WiFi are kind of material and power wise. If you go to the options of the advance of the WiFi adapter and change the WiFi output at 75%, this solves a lot of problems with the connection / disconnection of USB - C questions. Exit at 75% reduction does not affect your connection on wireless networks.

    My HARD drive kept connect/disconnect when you use the adapter, but this correction took care of her.

  • HP ENVY 5830 HDMI / DVI and external monitor not detected

    I have a HP Envy 15 with the ATI 5830.  I want to connect an external monitor.  The outside is a Samsung SyncMaster P2770HD and has a DVI (also has HDMI, but poor quality when used from a PC). My laptop has only HDMI.  When I use a DVI - D HDMI converter / my laptop does not detect that there is an external monitor.  I've lived all my settings and updated the Bios and video drivers.  I'm missing something. Appreciate any help.

  • Satellite 5200 903 does not detect the wireless adapter

    Hello everyone,
    I wonder if anyone can switch me to it...
    Since I reinstalled the operating system (my XP pro SP2) PC seems not detecting don't nor the wireless adapter in the device under network adapter Manager.
    Also the light of the flexibility wireless no longer not.
    I also have problems to access the BIOS to check if the card is detected there, have not a Toshiba HW setup in Control Panel as described in the manual.
    Any suggestions?

    Hello Juliana

    The question is how did you install the operating system? If you use the restore CD to install all tools including Toshiba HW setup. If the unit is pre-installed with the Microsoft Windows XP Home edition CD, you must install all the stuff of Toshiba late.

    Just a little explanation about the wireless network card. Basically, if the wireless switch indicator turns not on s clearly indicate on hardware problem. I guess that the wireless card is faulty. Also check if the card is listed in the Device Manager.

    If you want to enter the BIOS settings pres ESC key at the boot routine and keep it down for a few seconds.

    Good bye
