How do I connect my hp laptop to my lg LCD tv? I've tried plugging in the hdmi cable to both but my tv keeps sayin ' no signal' please help meeee :(


you need to select the screen you can use because most of laptops don't support to use both screens(laptop screen & monitor / plasma tvs that have VGA port) at once.. you can select your screen by check on F function buttons on your keyboard ...you can identify that button easily because it shows two screens on it just press that button you will choose the screen you can use.

Can't get my samsung hp-t4254 42" plasma tv to


make shure that the computer is set up to display on the screen. To check and see right click on your desktop, click on the option that says screen resolution, and then change your settings from their. The tv will not register that you have a computer plugged into it if the computer is not sending the tv a signal.

How do I get LG Plasma TV 42PQ30 to work with a dell laptop in connection use of a VGA/SVGA video cable. Thw hook up should act as a plug and play if my understanding is correct. I am using the RGB IN(PC)...


well, if the cable and adapters are friendly (meaning, you are able to plug the right video connection from LT to TV), sometimes you need to tell you LT that you have a second screen to output video. To do that, there should be a display icon in your bottom-right taskbar. Double click, and you should be able to see the options to either clone, pan, or primary your second display screen. :D

My LG tv shows no signal with hdmi cable to hp


First you need to state Mac G5 model and MacOS 10.?,? and whether the connection is VGA or mini-DVI. (I'm at 10.5.8.) I would not be helped by LG model other than to know if it is HD 1080 or 720. I'm going to assume you have MacOS 10.4 or later but most should apply. Apple>>About This Mac>>More info...>>Hardware>>Graphics/Display and read more about the display. Digital connection will give you more info. Close the Info but even with VGA you should be able to go to Apple>>System Preferences...>>Displays and have 2 windows--1 for the built-in and 1 for the external. If the latter is off screen, press Gather Windows. On the external display Turn on Show Displays in Menu Bar. This will let you control Mirroring and Resolution. You will need to pick a resolution your TV can do 1920x1080 1280x720 or possibly less to get started. My MacBook has all of those. I usually do not use mirroring and 1920x1080 gives a good pixel match to my DLP. On the external, turn on overscan if you need to put the menu bar on the screen or off if showing maximum of photos. You need to sync first, then play with other things. -Ken

Step 1
Shutdown your computer and look at the rear of the case to determine the type of video connections that your machine has. Nearly all computers will have the standard 15-pin VGA output port. In addition, you may also find that your computer has an S-video port, an RCA composite video port, a set of three component RCA video outputs or perhaps even an HDMI output port.
Step 2Determine the types of video inputs that are available on your plasma TV. There should be a standard RCA composite input, a three-jack RCA component input and an S-video input. In addition, you may also find a 15-pin VGA input, a DVI input or an HDMI input. Step 3 Select which type of connection you will use. HDMI and DVI represent the highest-quality connections, followed by VGA, Component, S-video, and composite. If your computer has only a VGA output and you will not using it solely to drive the plasma TV, you may want to invest in a video card upgrade. Most new video cards will offer dual monitor connections and possibly a separate TV connection. The first monitor connection is intended for the main computer monitor, and the second monitor connection, or the TV output, can be used for either a second monitor or a TV. Depending on the card, the TV output may be DVI, HDMI, component, S-video or composite. Step 4Purchase a video cable long enough to reach from your PC’s video output to your plasma TV. If the distance is over ten feet, you may want to invest in high-quality cables to ensure that the plasma TV receives a clean signal for the best possible picture. Cables over thirty feet in length, depending on the connection type, may result in poor video performance. Step 5Set your computer’s screen resolution to something that your plasma TV can accept, using the “Display” settings in the “Control Panel” in Windows. Refer to the owner’s manual of your plasma TV for the supported resolution and refresh rate. If you are using the S-video, composite or component outputs on your computer, this step may not be necessary. Step 6Connect your PC to your plasma TV using the appropriate cable. Start the computer up and it should recognize the attached display. In the “Display” settings, you will need to configure how the plasma TV is used if it is attached a second display. Most video cards support “Clone” or “Mirror” mode, which displays the same content on both displays. In addition, there is the “Extended” mode, where the second display will operate independently, and windows can be dragged from one screen to the other. If your plasma TV is the only monitor for the computer, you will not to configure the multiple display modes. Step 7Connect a cable from the sound output of your PC to your plasma TV using the appropriate audio adapters. Then relax on the couch and enjoy your videos on the big screen.

Lg 42PX4dv PC connection


I think the problem is the screen resolution and size of your pc is not matching the resolution size of your tv or is not compatable at the size you have it on or you may have to change to 4:3 ratio from widescreen. In your manual it will tell you the resolution sizes that you tv uses. You would probably be better also using the VGA to DVI lead, thats if it came with the tv (it does in the UK) as it supports higher wide screen resolution, whereas VGA will only support 1024 x 768 or there abouts.
