SOURCE: DVI input on monitor not working

Contacted viewsonic about this issue- they suggested- have both dvi and vga hooked up to same machine. start with poweroff on both. power on monitor, then power on computer. when you see display coming from the vga, power off pc, then disconnect vga cable, turn off power to monitor, disconnect power cord from monitor for 5 + seconds, reconnect power cord, power on monitor, then power on pc.
If this doesn't work to get the dvi working, (as happened to us) we returned our monitor for a replacement, since it was still under warranty.

SOURCE: "No signal detected" when LCD connected with DVI-D Cable

Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement

SOURCE: No display on SyncMaster 710N

I used 2 resistor of 100 ohms (1/8W) to make one of 50 ohms. Like others instruction, just put the 50 ohms resistor between pins 5 and 6 of this chip and the problem is solved.

SOURCE: I have the VE278Q which is connected by display

when you say monitor can't be found did you mean the monitor has no reactions when you turn on your pc?

here are some test you may need to do to know which part is faulty
1. Turn on your computer, did it display the monitor's logo on screen? When it does monitor is good, when only blank screen it could be the vga cable or the video card.
2. See if the led indication lit. When it lit to steady green, it's good signal is coming in from the video card. It should be followed by screen display. If no display it could be the backlight inverter lamp busted or faulty inverter board. When lit green then turns red, no signal coming from the video card. Check vga cable if fix properly to both monitor and video card. Or may need to reseat properly connection of video card from the motherboard. If no led indication lamp, then monitor is dead. Check ac power cord for continuity using multitester. Check power supply section in the monitor, replaced bulged or blown capacitor with exact value, this components were the first to get affected when lcd monitor failed o turn on.
3. When computer was turned on got display and then monitor turns black, go check the vga cable, Fix the connection properly or may need to replace it with new one.
4. When no signal appears or display blank screen after logo, then check video card. First remedy is to disconnect it the reseat properly to the motherboard. If this have no effect change your video card.

go follow these steps and let me know which is closely to your problem so I can give you a good advise.

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: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . 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.

What cord do I need to connect my 1810 gateway monitor to my tower


Your either going to need VGA or DVI. You need to check the back of your computer and monitor to see which type of connection you have. Then plug in the appropriate cable.

Hi, When I connect my Samsung RF711 laptop to my Sanyo LCD-42XR9DA TV HDMI to HDMI, and source the HDMI 1 input and press OK I do not get any laptop display on the TV screen at all. I have spoken to both...


I suspect that the TV can't read the signal from the computer on the HDMI port. You would get a signal from a VGA connection. (Computers send a slightly different signal over HDMI than a DVD or blu-ray player.)

In general, when connecting a TV to a computer, turn off both devices before connecting the video cables. Then turn on the TV and set it to the source (with the no signal message). Then turn on the computer. Next set the computer to output the video on the external video port. (Depending on the laptop, you may need to enable the port in the BIOS. To access the BIOS, press Esc, F1, F2 or F10 repeatedly as you turn on the computer. The key depends on the brand of computer.) Next set the video output in the OS (depends on the OS). For Windows 7, right click on the desktop (anywhere there are no icons or running programs), select Graphics Properties and set the desired monitor choice (laptop monitor, external monitor, both or extended). Click Apply and then confirm this when the display changes. (At least this works for my HP laptop on the VGA port.; my desktop lets me change monitors under Screen Resolution.)

The manual for the TV is available here: http://www.sanyo.com.au/resources/manuals/tvs/lcd42xr9da_im.pdf .

I wish that I had better news for you.

OK, mini display port to VGA adapter-is the VGA cord the one that goes into the port labeled RGB and audio on the back of the Samsung? Sorry to be a dummy but Samsung monitor is 6 years old and has always...


An RGB port is for a component cable not a VGA cable. A VGA cable, similar to a component cable, only carries a video signal but is a 15 pin cable that nearly all monitors and HDTVs support. Most laptops have a VGA out port.
You should be able to connect your laptop to almost any monitor (not sure about your Samsung) with a male to male VGA cable.

Good luck and thanks for using FixYa.

LCD VGA Display goes on and off.


Check refresh rate and setting for external display output. It won't work with unsuitable screen resolution, color depth or refresh rate. Check all three points and I believe you can troubleshoot the problem this way.

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

Bose 3-2-1 - trouble connecting to Samsung 26" LCD monitor


Sounds like you might be out of luck with the older 3-2-1 system. I am in the same boat, and am thinking I will only be able to utilize the "audio out" on the back of my Samsung LCD, and run that to the "aux in" on the Bose 3-2-1. This of course will not allow me to utilize the 3-2-1's DVD player, but by using a seperate DVD player, such as a Blu-Ray hooked to the LDC TV, the video will make it to the screen, and then the audio should make it through the Bose 3-2-1 speakers. Probably not the "best" solution, but one that I am going to attempt.
