A VGA & RGB port is the same thing. RGB is Red/ Green/ Blue for seperate input & VGA the video graphics array which does the same thing.
A DVi is an entirely different type of input port for digital input where your VGA port is more for analogue type inputs

How can i connect my laptop to my tv?


This will depend on exactly which model of laptop and TV. Look at the TV and determine what ports it has. Then look at the laptop for the same information. You may need to enable the external video ports in the BIOS. Turn off the computer and press F2 repeatedly after turning the unit on. (Some computers use Esc, F1 or F10. There will be a quick splash screen with the information.)

Then it still depends. If your TV and your laptop both have a VGA port, get a VGA M/M cable. (Often this is blue - it's a D-sub 15 pin connector.) This is the simplest option. Turn off the TV and the laptop and connect the cable. Then turn on the TV and set it to the VGA source (look for a button marked Input or Source on the TV or remote). Then turn on the computer; with most modern OS versions, it should set the correct resolution. You will need to enable the external monitor. This will depend on the OS. In Windows 7, right click on the display (where there are no running programs or icons) and select Graphics Properties. Then set the monitors to use the external monitor. Click Apply and then confirm the setting. Note: you'll need to also connect an audio patch cable (3.5 mm) between the laptop's headphone jack and the TV's VGA audio input if you want to use the TV speakers.

If your laptop and TV both have an HDMI port, you may be able to use that cable. You'll need to check the details on the TV. Not all TVs will read the computer's signal on the HDMI port. (The data isn't the same as from a set-top box like a Blue-ray player or cable box.)

If the laptop has a DVI port, depending on the TV, try either a VGA to DVI adapter or a DVI to HDMI adapter.

A few older laptops may have have an TV out (looks like S-video) port. In that case, you can connect to a similar port on the TV with a dongle and the cables.

For a TV with only composite or component input and a laptop without a TV out option, you'll need a VGA to composite or a VGA to component converter. These convert the RGB signal from the laptop to one that the TV will understand (component is YPbPr). See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-composite-video/c10000-c11200-c11213.html?sorter=productname-en-asc or http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc for examples.

Please add more information about your laptop and TV for additional help.

What kind of wire do I need to connect my samsung laptop to panasonic viera hd 3d plasma tv?


Most TVs will have HDMI and RCA component and composite jacks. Some TVs will also have a VGA port. Your laptop will have a VGA port. (If the laptop is fairly new, it may also have an HDMI port.)

Not all TVs will support an HDMI signal from a computer, so the VGA signal is often better. However, that limits you to SD (anything with HDCP will fail.)

Very few TVs ship with the HDMI or component cables. However, there are some vendors who do package the HDMI cable with their TV. Without knowing which exact model of TV and laptop, I can only make a few suggestions. I know that the TCP42ST30 (Plasma 42") doesn't have a VGA port.

Look at your laptop for any external monitor port. VGA ports are generally blue female ports with 15 holes (D-Sub). If your TV has a matching VGA port, get a standard VGA monitor cable.

If you have the VGA port on the laptop but not on the TV, you can try a converting from VGA to HDMI. (You may need a DVI to VGA adapter and either a DVI to HDMI cable or a DVI to HDMI adapter.) Note: this gives an analog signal (RGB format) to the TV. You'll also need to make sure that your VGA port is active (in the BIOS for some computers) and then set your computer to send the signal to the external monitor. It is best to turn off both the computer and the TV before connecting the two. Then turn on the TV and set it to the correct input before turning on the computer. (In Windows 7, I set the video signal for the external monitor by right clicking on the desktop and selecting Graphics Properties. Set the signal to the external monitor and click Apply. Then click OK (in the external monitor's screen).)

If this doesn't work, you need a VGA to component video converter. (Not a VGA to component video cable - those are for projectors that read the RGB signal.) See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html .

Some laptops come with an HDMI, mini-HDMI or a DisplayPort option. For the latter two, you will need the appropriate cable with that end and the HDMI connector on the other. Then connect the TV and the computer as described above. (Note: my TVs accept a computer signal at the HDMI port labeled HDMI/DVI. However, you need to make sure that your TV understands this signal. It isn't the same format as that from a set-top box. My laptop has VGA and HDMI out; the desktops have VGA, DVI and HDMI (on one).)

If you add a comment with the model of your TV and laptop, I'll be glad to give you more specific options to connect the TV and the computer.

I hope this helps.

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.

How to turn on rgb from lap top to tv.


In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

Can i use my lg lcd 19 inches as a pc monitor which have a rgb port


Your TV must have a VGA port. Look on the back for the computer hookup. It will be like a trapezoid shape with several holes that the VGA cable from your computer will plug into.
If so, go to the menu and highlight VGA input to operate.

How do I connect a PC to a LG50PG20 50" HDTV Plama?


You need a VGA cable (15 pin) connected from PC (monitor out) to the PC input on the HDTV (15 pin) this is for the video. For the audio, connect from PC to HDTV, audio cable, either 3.5mm from earphone out on PC to HDTV 3.5mm audio input (next to PC VGA input) and also be sure to set PC screen resolution to compatible output for HDTV like 1024 X 768 or 600 x 800 etc.

What do I need and how do I connect my Toshiba L305 model PSLB8 050302f to my hdtv to view online tv?


I dont believe that laptop has an HDMI port on it. If you have an LCD TV then your TV may have a VGA or DVI input on it. You can connect your laptop to the TV by using a VGA to VGA or VGA to DVI cable. If you your TV doesn't have one of these input ports, then you're not going to get your laptop connected to your TV.

How do you hook up the tv thru dvi out with a sony pcv-rs620g


There are several ways to do this. The two best are:

1. Get a DVI to HDMI cable. This will allow you to plug directly from your computers DVI to your TV's HDMI.

2. If your computer has an analog (rgb (vga) 15 pin) input, you can simply get a dvi to vga adapter and plug into that port.

Currently, I am using option 2 for my own use.

In the photo below, I point out the HDMI, RGB (VGA), and audio inputs. You must use the audio input but you have a choice of using the HDMI or RGB for video input from your PC. If you have the extra HDMI slots, I would use that. If not, the RGB is fine.

Can i connect toshiba satellite a205 to tv?


Yes VGA carries RGBHV--RGB and Horizontal and Vertical Sync information along with DDC info where available.

Now is that port on your TV a d-sub 15 pin standard VGA connector?
http://en.wikipedia.org/wiki/VGA_connector

If it is, then yeah you should be able to output VGA from a PC to the TV with a proper cable.

However if the TV has DVI or HDMI connections on it, it's better for you to connect it that way. DVI/HDMI is a digital signal and if it's a digital-based display tech TV, then you're better off using that. Also if the TV does resolution above 1360x768 (i.e. if it does 1080p) you can get higher resolution by going via DVI/HDMI...
