    Hi Anonymous, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
    we need lots for information what is connected here. I guess screen #1 is the internal screen? and 2 is the AL1706 vga >HDMI and Pavillion? what Pavillion is model.
    my wild guess is >
    1: Pavillion not set to dual mode. (see manual)
    2: that unknown hdmi adaptor is not working.
    3: aL1706 tested ok, it's old and old monitors do fail,for CCLF back lamps dead, (4:5 square screen monitors are mostly dead now. )
    4: PC runs windows. windows what?
    5: PC will not see, the old 1706 connected via HDMI, how can it, ?
    6: the AL1706 has poor resolution, so you will need to lower (poorer) to get it to work at windows PC. 1280 x 1024 or it will not work.

    step 1, take your 1706 and its vga cable
    and test it on any PC made with a VGA jack.
    and test it at above resolution first
    that mean set it first, in windows
    then plug in the the 1706 next,.
    i bet the monitor is dead, as 99% are ow.
    the CCFL tubes die fast, and go DEAD.
    fast means 5 to 10 years.
    yours is 11 years old, 3 year before those far batter LED LCD monitor took over the market.
    id retire it, i have 2 in the attic now.
    both went yellow lamps (near ***** )
    ugly yellow for white.

Can I hook up a HP L2245wg monitor to a Hp envy laptop

Probably not very easily. The monitor only supports VGA 15-pin and DVI-D video connections. Although you don't specify which ENVY model you have, most only have HDMI and/or DisplayPort outputs. You would need an HDMI-to-DVI-D adapter/converter for the video, and, of course, DVI-D and VGA do not support sound, although it appear the monitor does not internal speakers anyway. You would be better served using a monitor with HDMI input(s) with this device.

VGA-HDMI connection fail on Acer projector using adapter

You don't say whether or not the "adapter" is simply a gender-changer, or if it actually converts the digital signal from the HDMI port to an analog one for the VGA port. Some monitors have both analog and digital input capability and can automatically adapt to the the digital signal, even if applied to the VGA (analog) port. Other devices are not so smart and need an actual digital-to-analog converter style adapter.

You should try this monitor and the video cable with another PC to see if it works OK, or try this laptop with another monitor to see which one is not working, I have a feeling something has changed in the laptop setup.
Please post back what you find.

Does the Acer Aspire R1600 support extended desktop/dual monitors with the VGA and HDMI ports?

Yes it does. After hooking up the external monitor simply right click anywhere on the desktop, select properties, settings, and then change the monitor profile to your desired setting.

Good Luck,

I just hooked up my HP Pavilion 9000 Laptop to my Vizio TV and put the TV on correct setting. It is not working on the TV, any ideas? I went on Display setup and kept trying to connect but it says the...

If your laptop has a VGA port, your Vizio needs to have a VGA port too so you can use a standard VGA monitor cable.

If your laptop has a DVI port, you hook it up to the Vizio using a DVI-to-HDMI cable.

And if your laptop has an HDMI port, you hook it up using a standard HDMI cable.

Hope this helps.

You can connect any HDMI or VGA (15 pin) compatible monitor or TV, almost every monitor has VGA connector or VGA adapter at the end of connector and you can use it.
