Acer AO722 :: Windows 7 - HDMI Is Not Working When To Connect To TV
Feb 19, 2015
I have an AO722 with Windows 7 64 bit.
I am trying to connect by HDMI to a TV.
TV says no signal.
Have toggled through all of the options with the fn f5 and f6 keys and also the Windows button/P also.
My screen would go black on some options but still no signal on the TV.
Went in the Device Manager to see if the HDMI port is there with the USB's.
Could not find. Is this possible issue or something else?

I am trying to use my TV to view some of my notebook content and some internet stuff using an HDMI cable instead of a serial cable. When I connect the HDMI cable to the TV and change my output the TV displays "no signal" and then "device not configured" or something like that. Am I doing something wrong or can I only connect with a serial cable?

Everytime windows updates my Acer AO722, windows will not start. This started after I did a factory restore. When shutting down windows updates my system and then windows 7 will not start up after a restart.

How to connect my Presario CQ61 Notebook to a Philips TV via HDMI under Windows 7. I checked the settings in the control pannel in Windows 7 and set them to multiple displays. Under the NVIDIA control panel I cloned the displays. Nothing happens, black screen on the TV with "no signal" message. The Notebook is recognizing the TV correctly by the way.
I already spent 2 hours on this. Tried various articles online, but nothing seems to work. The HDMI cable is OK. I successfully connected a Playstation console to the TV. Seems it's not a hardware issue, but something with the settings of my notebook.

I have an Acer Aspire V3-572g. My laptop came with windows 8.1 installed already. Currently, my pc is being reset to factory settings because I can not figure out how to keep the hdmi from going out after windows updates. The only way I can keep get the hdmi port to work is the factory reset it. The only way from keeping the hdmi working is by turning off windows updater. However, I'd like to figure out how to keep the hdmi working without doing so. My graphics card is Nvidia 840 M. Here are a list of things I've done after my laptop stops recognizing the hdmi.
Uninstall and reinstall the display drivers, both from intel and Nvidia
Update the drivers to be up to date
Downloaded intel's utility manager to keep driver update to date
Downloaded factory installed drivers from Acer's website
Contacting microsoft and have them remotely connect to my laptop
Restored back my laptop to previous working conditions (although the hdmi never worked by going to a restore point)
Swapped hdmi cords and displays
After several hours of researching and trying different things I'm stumped. I bought this computer with the sole purpose of connecting it to a TV. I've also had this issue with another laptop which I returned. This problem isn't a hardware problem as I'm connected to the same monitor with an old desktop using the same cords. I'm guessing there is a compatability issue with windows and the display drivers when there is an update.

I have an AO722-0825. I'm looking to increase the speed and performance of this machine, and so I wanted to upgrade the memory (and possibly swap in a SSD). So my questions are:
1) Is it possible to upgrade the memory on this machine?
2) What brand of memory does Acer?
3) taking out the hard drive and putting in a solid state drive?

I have recently purchased Dell Inspiron 15R 5521N laptop with Windows 8 Pro. When I try to connect my laptop to an Acer monitor with an HDMI cable, it gives me a no signal error. But when the same laptop is connected to a Philips monitor using the same cable, it works perfectly. As usual I thought that the monitor was the culprit, but when I connected another laptop to the Acer monitor using the same cable it worked without any errors. So where does the problem lie. The HDMI cable is OK, the laptop is also OK as also the Acer monitor?

I am using an Envy TouchSmart 15 and I have just run an update of Windows 8.1 based on the system auto update (it ran 5 updates).
Prior to the update, I used a 27" monitor as the main screen and this was connected via the HDMI port. Right after the update, the system doesn't seem to recognise the HDMI port anymore and it goes back to using the Envy laptop screen as the main screen. I changed the HDMI cable but it made no difference. I subsequently connected another laptop to the 27" monitor via HDMI and it worked fine. So it appears both the monitor and the HDMI cable are fine.

I am unable to connect my XPS 1330 to a Dell 2408 monitor via HDMI. I am running Vista Business and the 1330 has the integrated Intel graphics chip. Connecting the two with a VGA connector seems to work, but not via HDMI.
Also anyone have experience with the "Display port" input on the Dell Monitor? What is that all about? is it basically HDMI without sound, or something like that? Why have that and still have the DVI inputs?

Everything was fine till I formatted my HDD and installed Windows 7 (wanted to try it).
I have a HDMI cable from my laptop Aspire 5738ZG to my PHILIPS HD Ready TV. Now the picture shows just fine but I've got no sound at all on my TV.
I have tried reinstalling a lot of drivers without success . If anyone knows what's causing this problem please tell me, as I really want sound on my TV while watching movies etc.

I'm trying to connect my Pavilion dv6 to my HDTV using an HDMI cable. I'm getting video, but not audio from the TV speakers. The problem started after I upgraded from Vista to Windows 7. I had no problems with HDMI with windows Vista.
I've tried updating/reinstalling the audio drivers from HP's website, but it doesn't work. I've also tried going to the control panel and changing the playback device, but the HDMI audio device icon no longer appears in the playback devices dialogue box. The only playback devices are Speakers and Dual Headphones, Independent Dual Headphones, and SPDIF (Digital Out Via HP Dock.)
Why is the HDMI device not shown in the playback dialogue box?

I just recently purchased an HDMI compatible television, for the purpose of extending the screen on my Acer Aspire E1-510P-4402.
At first, I thought it might have been either a faulty HDMI cable, or television. This is not the case, however. The television works perfectly fine on another computer, using the same HDMI cable.
Since I isolated the problem to the laptop not recognizing it, I tried to reboot my laptop, yielding no result on the second screen.
I also downloaded the latest version of the VGA Driver (Intel HD Graphics) from the Acer driver support site, then uninstalling the driver in Device Manager (and removing the driver files) -> rebooting -> reinstalling the driver (to be 100% certain of the latest version) -> then rebooting again. This also did not work:
I also did the same thing with the Intel Chipset driver, seeing as it may have been a conflict between them. This resulted in no effect.
As a final measure, I also downloaded the Intel driver updater and installed it. The updater told me that a generic version of the driver may not work, and to contact the manufacturer for support with it.

G60 laptop is working fine with all the latest driver updates...all windows updates... running windows 7, except that when i plug in the hdmi ..... to my toshiba tv... or any other tv for that matter.... the image of the desktop will not display on the tv.... yes its all hooked up right..... but what does happen is that the display adapter recognizes the tv... it will show it { TOSHIBA TV } on the drop down menu...
When the cable is connected... you hear the default windows " yes im connected" sound & when removing the cable... the default "disconnect" sound is heard....
So the pc is recognizing it....but still no image at all on the tv .... cant identify... I've tried 2 different cables & 3 different tv's.... all the same results.....

My new Lenovo Z580 runs windows 8 64bit, core i3 3rd gen, 4gb RAM.
The problem is, since day 1,every few minutes the internet stops working. It shows as connected, the router is working, other connected devices run as intended and everything's fine. But internet doesn't work on my laptop. It says "Could not connect to the network". I have tried doing the "keep wifi on during sleep" etc. but nothing works. It just stops working after a while even though I am using the laptop, it just suddenly stops. It even shows as connected, and packets are being received but internet or any application over the internet will not work untill I disconnect and reconnect.

I've been sitting here for hours trying to figure out how to get my tv to work with my hdmi port on my dv6700. No matter what I do the computer doesn't detect the tv, so I can't set it as a second monitor.
I've updated the nvidia drivers to no avail, I can't think of what else to try.

i have HP 2000 notebook and all of a sudden HDMI port stopped working. Factory restore and a chipset driver worked and it started working. my bad, i installed a graphics driver, that took me back to sqaure one. HDMI port on the laptop is not working. HDMI cable and TV HDMI port is all working.i ran HP support assistant and it shows all required updates are in place. though it worked in between, it should be an issue with the chipset driver.

I have a xps15z and the hdmi connection suddenly stopped working about a week ago. I have tried everything I can think of to get it working again, reinstalled drivers, tried different leads, different monitors but no success yet.
The weird thing is when you plug in the hdmi lead the external monitor is detected on the nvidia control panel and the windows display settings. Also I can scroll across to where the extended screen is and drag windows over there but nothing shows up on the monitor. The monitor says there is no connection.
Relevant system specs: windows 7, nvidia Geoforce GT 525m graphics card (runs the external display), Intel(R) HD Graphics family (runs main laptop display).
