Link ASUS laptop to Sharp Aquos LCD TV

No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

I run a PC with the newest sandy bridge hardware and a Msi GTx 560 Twin Frozr II video card (dual Dvi-I input and a mini-hdmi input). I also have a BenQ G2222 monitor (one VGA input and one DVI-D input),...

The problem might be with your ram. Try taking it out and putting it back in. You might also have a problem with the video card. Make sure it is secure and screwed in.

I just purchased a acer h203h and when I hooked it to my computer it says no signa and light turns red.

Please check the video input selected, press Menu botton, the monitor will show you among other information the input selected, if indicates VGA, you must have connected the corresponding cable between your PC and monitor, if it indicates DVI and your computer doesn't have DVI port press the Input botton to select VGA.

How do i connect to an hdtv ?

You're going to need to connect a cable supported by BOTH the PC and HDTV. Check your HDTV's jack panel or manual. List the types of Input jacks it offers. The HDTV will likely have Component, Composite, DVI, HDMI and maybe even VGA jacks. Do the same for your PC. It likely has one or two Video Output jacks. Typical Video Outputs are DVI and VGA. The VGA type has been standard for years. It consists of a total 15 pins in 3 rows. The DVI has a number of pins, but most noticeable is a wide tab at one end of the jack.

If your HDTV has a jack that matches one of those found on the PC, you're in luck. Purchase a cable that will connect them - this would be either a VGA cable or and DVI cable. Nearly any inexpensive VGA or DVI (Digital Video Interface) cable 6 ft or less will do, but the better cables cost a bit more and when the distance is increased, the quality (or lack thereof) really becomes visible - especially on the lager HDTV screens.

If you want the sound to go to the TV speakers or elsewhere, you'll need to get a cable with a 3.5mm stereo plug (or whichever type your PC has - but that's the most common) to RCA or whatever the audio input jack type is that is associated with the video input you chose. The audio input must be the one associated with the video input - other wise you will not hear the audio on input 4 while watching input 3. The PC audio out is analog, so do try to put the signal into a digital input.

If you don't have a matching video input jack, you'll have to purchase an adapter or new video card with jacks that match your TV. Do not buy simple adapters that change VGA to DVI as they will not convert the actual analog VGA signals to Digital Video signals expected by the HDTV's DVI jack. The best bet is to buy a modern video card supported by your computer's mother board and OS that has a fair amount of memory (512 MB is a good start). If your HDTV has HDMI jacks and you wish to play the sound from the HDTV's speakers, get a card with HDMI output and buy an HDMI cable. It will send both the sound and video to the HDTV for you.

You can read a nearly endless list of articles about HTPCs aka "Home Theater Personal Computers" for ideas and deep discussions about everything from soup to nuts to implement, design and set up on google.

I hope this helps - good luck!

If i connect the DVI cable to my Video card (9200 family)and to my monitor an Asus VH222H i get a dialogue box saying no DVI signal. if i use the VGA cable everything works fine.Does this mean the card...

Make sure your monitor is set up to recieve what ever signal you are wanting via the monitor's menu. There should be an input button on the monitor to select the signal type. The connection really doesn't matter as long as you are able to use the monitor. There could be something wrong with the connector on the video card. Also make sure you are using the card and are not using the onboard graphics connection by mistake. If the problem persists it is more than likely the card.

Can i connect a dvid cable from the monitor to my flat screen tv hdmi to watch videos from my computer? Thank you Martin

the Flat Screen TV if has, a HDMI input, also has VGA Input.

You must choose :HDMI or VGA, if HDMI The VGA board must Have HDMI Connector, and you connect a HDMI cable to the TV.

The HDMI is a digital signal input/output, VGA is Analog Signal. You must have Signal Converter if you Use the 2 signals
