Question about Acer Aspire 5100 Notebook

Can no longer connect laptop to television

I have an AKAI HDTV, a VGA cable, and have been connecting my laptop to the television successfully via the FnF5 toggle key. The last time I tried to connect, the icons did not appear when pressing the toggle key. There used to be three, now only the computer one appears so I can't select the television icon to switch my computer screen to the tv. What happened and how do I get them back?

    Thanks so much for all of your time and information-BUT-before trying I should have been more specific-I have windows VISTA. Same procedure?

  • Anonymous Sep 19, 2008

    I am just trying to do this for the first time and it is not working for me either. I have an Acer Aspire 5100 running Vista Home Premium. I have connected a VGA component 3 RCA cable to my tv which is a Uniden and have also connected the red and white parts of a composite cable from the headphones part into Video 3 (same as what the VGA is going into) and I can hear the sound coming through the TV okay but no picture, even after pressing Fn F5 my laptop display goes black but no picture on the TV. Any help would be much appreciated!! Thanks =)

Hi there Susie
Assuming your running XP....

Go to Start
go to control panel
then display
there should be two screens visible
click on screen 2 and then IDENTIFY
the video card should then put a Number 1 or 2 on the screen if its connected and turned on,
If there is only one screen visible in the display SETTINGS
then you will have to uninstall the device and reinstall it.

How to Uninstall....

Go to start
Right click on My Compter,
Device Manager
Right click on Display adapters
Reboot to save settings when done and restart

On start up the Operating System should auto recognise the device and reinstall it,
It will tell you when its installed and ready for use ,
give you a device install failure message
Try again.

Once this is done the device should be up and laughing again.

As far as how did it happen???
Did you do any device updates or software installs lately?

Sometimes default settings of different softwares conflict with each other and the only way to sort them out is turn them off and start again.

I hope this helps,If you need any more help , please just ask

    this a similar aproach to this same situation

    but there are extra passwords required before anything is changed,

    Uninstall your device it will ask for a password before it does anything,ie add or remove software,reboot and restart,

    Vista should sort any issues out itself,leave it to sort itself out,

    Please let me know if you need more help,

Have wireless internet need to connect tv to hp laptop

If its portability and convenience you're wanting to achieve you can connect your tv to your laptop via a hdmi or vga pc to tv device such as the one below.

wireless-internet-need-connect-tv-hp-h3kz2pmtsa0m5tqtbi05zsqk-5-0_1.jpg Or you could set your close lid settings to "do nothing" when lid is closed" and set it to "never sleep" when connected to AC power and use either an hdmi cable or male vga to male vga cable to connect to your tv. You will need a wireless keyboard and wireless mouse because u will no longer need to physically access your laptop. Make sure your tv input selection is correct. For example, hdmi 1, computer, vga, and etc.

How to connect my acer D255E to the TV

According to the limited resources that I could find your only video output is a VGA port. Most newer televisions, predominantly LCD televisions will allow a direct connection via VGA. If your TV does not support VGA, can try using:
VGA to HMDI for HDTV's - Amazon search
With these I typically recommend a full force converter over a cable, but often times cables will work. Remember that with a VGA to HDMI cable only, this will only pass video and not audio. You will need separate cables for audio.
If you have a non-HDTV try this:
Use either S-video or RCA connectors to your TV.

How can I connect my Desktop computer to my Hitachi 57F500 TV? I have an emachines desktop, running MS Win 7 connected from Monitor VGA port to DVI port on TV via Dynex DVI-VGA cable, but not getting any...

VGA and DVI are not compactable. Your TV has no provision to connect it to computer.

DVI-HDTV Input (Input 1)

Use this DVI-HDTV Input for your external devices with DVI-HDTV output such as a Set-Top-Box, high-band DTV decoders, DVD
players and D-VHS with Digital Content Protection

1. Only DTV format such as 1080i, 720p, 480i and 480p are available for DVI-HDTV input.

2. The DVI-HDTV input is NOT compatible when used with a DVD player from a personal computer.

3. When connecting a Set-Top-Box with a copy-protect digital out terminal, a high definition picture can be displayed
on the screen in its digital form

I am trying to connect my laptop via VGA cord to my 65" Mitsubishi Medallion, but when I click on the VGA device selection in the device menu, it goes to a blue screen and says "Warning: Turn on...

Press the Windows key + P on your laptop.
Or, if that doesn't work, look on your F keys for something that looks similar to a monitor.
Press the FN key and that key.
This should bring up your laptop's display on the tv.
