Question about LG LW20-EV Notebook

1 Answer

I have my laptop hooked up to my Sony LCDTV (using it as a big screen) via HDMI cable, but now the laptop screen doesn't work. I disconnected the HDMI cable and restarted the laptop but the screen comes up blank (not blue, just a grey colour). I hook it back up to the tv and it works fine. What could be wrong?

Go into your display driver, and make certain you have it set to have the internal LCD as your primary display. There should be an option to go ahead and have it either act as a second display just cloning what's on your screen or to have it extend. (select the option to clone)

    Found this option but it won't save the changes. When I went into the display driver it showed the TV as the primary so like you said I changed it to the laptop (primary) and tv (secondary) and cloned it, then applied it, hit OK and closed out of that portion. Once I go back into it , it has reverted back to tv primary...arrrgh!!!

Can someone please help me get my laptop working through HDMI cable onto TV on a sony VAIO VGN-FW23G. I need to know the process to do this


1. Check the computer for changing output (some computers use <F5>, <F8>, depending on which brand they are. I believe Sony uses <Function><F7> or <F7>).
2. Check what channel the HDMI port is on (e.g. AV1, HDMI1, HDMI2, etc.) - you need to know this if your TV doesn't automatically switch to the new input.
3. Plug the HDMI cable into the TV HDMI cable-in port.
4. Plug the HDMI cable into the laptop HDMI cable-out port.

5. Turn on the computer.
6. Press the <Function><F7> simultaneously ONCE. The screen should flicker and show up on TV.
7. Sometimes you may have to go to "Display Preferences" and select Dual Monitors or external monitor if your computer doesn't do it automatically. Repeat Step 6 after.

** You may have to adjust Display Resolution to 1024 x 768 or lower in order for the TV to work. After it works at a lower display (800 x 600, for example), you can adjust the resolution to the maximum the TV can accept.

Polaroid tlx-01911c hdmi with laptop says not support!


You either lost HDMI on the TV or the Laptop. The way to tell is hook up the laptop to another set aand see if it works. If it does than the problem is in the Main PCB of your TV.

I am trying to hook up a Sony BDP-S360 via HDMI


I don't know what kind of TV you have, but on some TVs the HDMI inputs have to be enabled via the TV setup menu. Try looking at the setup status.

No play back from HDTV to threater system


Do you have set-top-box or antenna-cable directly to TV?
You have connected TV with received via HDMI, but that won't work in this direction - TV has HDMI INput only, not output.
You can use HDMI to connect HDMI-out on DVD player for example to HDMI-in on receiver and HDMI-out of receiver to HDMI-in on TV.
But to get sound from TV to the receiver, use spdif optical or coax cable if TV supports that - this way you will get surround sound.
But also your connection via analog white/red RCA plugs should work, but only for stereo sound.
