Make computer display fit tv screen mitsubishi wd 65738

That TV is suppose to have automatic input detection but if it doesn't work you can press the input button on the remote and then use the arrows and enter to select the input you are trying to use.

It will depend on the laptop's available external video ports. You can connect a VGA cable from some laptops to the VGA port on the TV. Then plug in a 3.5 mm audio cable from the headphone jack to the PC audio in port. (The audio connection is optional. You could continue using the laptop's speakers.)

Make the connections with the TV and the laptop off. You may need to enter the BIOS to enable the external video port. (It can be turned off to save power. The BIOS is accessed on boot by pressing a key (Esc, F1, Del) noted on the splash screen. For Win8 machines, you'll need to do a special restart.) Then turn on the TV before turning on the computer. The TV monitor should be automatically recognized for resolution and refresh rate. Next, if you have a Windows system, right click on the desktop (pick a spot with no icons or running programs). Click on Screen Resolution (or perhaps Graphics Properties, depending on the OS). Set the monitor to duplicate the screens or send data only to the TV screen.

I'm not sure if the HDMI ports will understand a computer signal. (Not all TVs can interpret the computer's HDMI signal; it is different than that of other set top boxes.) You can try the following connections.
If your laptop has a DVI output, use a DVI to HDMI cable (or adapter) to connect to the TV. Then connect the HDMI cable to HDMI 1 and use the PC audio connection as above.
For an HDMI output, use an HDMI cable. (You will still need the audio cable unless you can reset the audio signal to output on the HDMI port. Go to the Control Panel and then the Hardware and Sounds section. Under Sound, select Manage audio devices. Then in the Playback tab, make the HDMI audio the default.) For Display Port or Thunderbolt outputs on the laptop, you will need a DP to HDMI adapter.

If the HDMI port doesn't understand the computer signal, you'll need to use a converter to go from the computer's output to component video or to VGA. Then connect the converter's output to the appropriate port on the TV.

I hope this helps.

(To access the Control Panel in Windows 7 and earlier versions, click Start and then find the Control Panel in the right hand column. For Windows 8, press the Windows key + X (or access the Charms menu on the right-hand side (Win+C) and choose Settings). Then select the Control Panel.)

never plug in hdmi when comp.is on you may burn your hdmi port

The Emerson LC320EM1F has an HDMI connector (HDMI 1) that can be connected to a computer with an HDMI out or a DVI out. With a DVI connection, you will need a ferrite core on the HDMI cable. You can use a DVI to HDMI cable or a DVI to HDMI adapter with the appropriate cable. You will also need a 3.5 mm to RCA (M/M) audio cable (or the adapters and cables) if you want to use the TV speakers. If you have only a VGA output on the computer, you will need an analog to digital converter (like this: http://www.startech.com/AV/Converters/Video/VGA-HD-with-Audio-to-HDMI-Format-Converter~VGAHD2HDMI ).

You can find the manual for this TV including the connections here: http://www.emersonaudiovideo.com/support/download.php . Enter your model number and then the list of manuals will appear. The connection to computer diagrams is on page 13.

Once you have your cables (you will get the best prices from an online shop), turn off both the computer and the TV. Connect the cables then turn on the TV and set it the HDMI 1 input. (Use the Source button on the remote. You can also press CH Up repeatedly.) Then turn on the computer. If your computer has a recent version of Windows, it should see the TV automatically if the port is active on the computer. For a laptop, you will need to change the display settings to use the TV monitor. Right click on the desktop (anywhere there are no icons or programs), find the Display properties option. Set the monitor option to use the second screen (extended or monitor only). Click Apply and confirm the setting on the pop-up. (These are Win7 directions; other OS versions will be similar.) For a desktop, you may need to go to the Screen Resolution option after right-clicking. (This is a shortcut to the Control Panel Display settings window. Thus you can also click Start > Control Panel > Display to get to the right area.)

Some machines may need the port enabled in the BIOS first. This applies more often to older laptops or those with a power-saving option that turned off unused ports. You will need to enable the port with a different monitor active before connecting to the TV. Accessing the BIOS varies but usually involves pressing Esc, F1, F2 or F10 repeatedly after you turn on the computer. I often miss the timing; just turn off the computer and try again if the OS loads or the log-in screen appears.

If you get an unknown mode message on the TV, the previous monitor may have used a refresh rate and resolution that the TV can't understand or the TV was turned on after the computer was turned on. If it's the second case, press CTRL-ALT-DEL twice or turn off the computer (you will see a warning that Windows was improperly shut down). Then turn on the computer. If you have the first issue, go to the previous monitor and use the Screen Resolution directions above. Set the refresh rate to 60 Hz. Set the resolution to 640 x 480, 800 x 600, 1024 x 768, 1280 x 768 or 1380 x 768. (The options will be limited to those that are compatible with this monitor.)

I hope this helps.

(Note only HDMI 1 supports a computer signal; the other ports will not understand the computer's video output.)

you have to select the monitor out on the computer is ether the f1 or f2 key on the laptop

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.

(A DVI port is a digital video out option with ~21 pins and is usually white.)

Look for a button on the remote or the TV itself labeled Source or Input. This should let you change the input between TV, AV, HDMI (on some TVs), and PC. Just press the button repeatedly or use the up/down arrows.

Before setting the input to PC (VGA), turn off the TV and the computer. Then connect the VGA cable (M-M) and the audio cable (a 3.5 mm M/M cable, if you plan to use the TV speakers) between the two units. Next turn on the TV and set the input to VGA. Then turn on the computer. (This is if you are using the VGA or D Sub 15 connection.) For a desktop, if you do not have another monitor connected, the TV should automatically be detected and the resolution set with any Windows OS (XP and later). However, you may need to reset the resolution and the refresh rate. For Windows 7, right click on the display and choose Screen Resolution.

For a laptop, you may need to enable the video port in the BIOS. Accessing this depends on the manufacturer of the computer motherboard. (Often Esc, F1 or F2 is the key to press after turning on the computer but before the OS loads. This can be tricky to time correctly.)

With a laptop or a desktop with another monitor attached, you will need to tell the computer how to deal with the multiple monitors. (Extend, monitor 1 only (or laptop internal monitor), monitor 2 only (external monitor), or dual display.) For my HP laptop with Win7, I choose Graphics Properties instead of Screen Resolution. There may be a keyboard Fn shortcut to access this.

Some TVs will accept a PC signal on the HDMI port (directly from an HDMI port on the computer or via a DVI to HDMI cable). Not all TVs do this. (Without the model for your TV, I can't confirm if this will work. If it doesn't, it is because of the differences between the PC output signal and that of set top boxes (cable or blu-ray players).

I hope this helps.

Try these options
1. Click on sound icon in Taskbar and make sure sound is up on HDMI volume. If this doesn't exist-
2. Start => Control Panel => Hardware and Sound. Under Sound tab click on Manage Audio Devices, right click on HDMI tab and enable. Or this: Computers have two seperate systems - one for video and one for sound.

The only computer (or laptop) connection that carries both video and sound is HDMI. If you do not have a HDMI/DVI connector on the back of your computer, then you will have to use the VGA-composite or s-video connectors to display your PC's output on an external monitor like an LCD TV.

On both my HP and Dell laptops the display settings (Start/Control Panel/Personalize/Display Settings) allow two modes - single or dual monitor mode. Single monitor mode allows me to switch between any one of three possible video outputs - VGA-composite, S-Video or laptop screen, or a split-desktop (display spread over two seperate monitors). Dual monitor mode allows the same display on any two of three possible video outputs.

Switching is performed using the fn keys on the keyboard (fn key plus the F2, F8, etc. function key with the display marking). You guys use single monitor mode until you figure out what your are doing. Select VGA-composite or S-Video.

Non-HDMI sound to your TV monitor or sound system must be obtained from your laptop's Headphone or S/PDIF jacks. Headphone is stereo and S/PDIF is 5.1 surround sound. Headphone is electrical, but S/PDIF may be electrical or optical (laser light). You must set the sound jack that you intend to use as the default on the PC control panel (Start/Control Panel/Sound).

None of these connectors is two-way in the context of an LCD monitor - your PC cannot record a TV picture or sound from the external monitor. To accomplish this you must purchase a video converter box that converts cable TV or video+sound inputs to USB format usable by your laptop. Do this and you can turn your laptop into a Tivo recorder/DVD burner using Beyond TV, Sage TV or a variety of other software packages.
