Re: Using 42HP66 as a Computer Monitor for a Compaq...

Reboot your PC! When the pc starts booting up push F8 it will take you to the same screen asking you if you want to run the pc in safe mode! What you want to do is to select the Start PC in VGA mode! It should set your video card to a default setting allowing it to work with the TV!

I hope this helps you!

Please feel free to call or message me if you need more help!

Connect the camera to your desktop by proper connecting wire, and switch both computer and camera. If the desktop detects the camera, it will be noted at the monitor, and will ask for firmware disc. Insert the disc and follow the instructions.

Trying to connect computer to LCD TV and get no signal?


If you are trying to connect computer to LCD TV and get no signal, as a first thing do the following:

Double check cable and connection. If possible test different connections. Try using VGA, DVI or AV, depending on availability on computer and TV.

Ensure that Video drivers on computer are properly installed, and that the video adapter is working properly.

If you are using a laptop, ensure that you do not need to use a function button to enable the external display, this is pretty common on laptops.

If you are using a desktop, go to display properties, find the windows where you get the picture of two monitors, and ensure that both monitors are enabled.

On Vista try also using the 'Identify Monitor' button on Top. It is located on same properties panel as the two monitor, the main Display Property windows. From the same window you can also modify display resolution, as explained later.


If still no luck, then it may be a problem of synchronization between TV and computer, in that case try the following.

  1. Turn off TV.
  2. Disconnect TV power cord.
  3. Restart computer.
  4. With Computer already on, plug back and restart TV.

....If that does not work.

On computer, go to display properties.

First try changing computer resolution. The TV max resolution may not be available on computer. In that case try lowering down to the smallest 16:9 resolution available on computer graphic settings (usually LCD TVs are 16:9), and if that does not work, set resolution to 800x600, just to test (picture proportion will be distorted, or you get squared box on a 16:9 TV).

If that does not work, open Display Properties. In Display Properties access Advanced, and then Monitor settings (XP). On Vista choose Personalize in control panel, then Display Settings, and go straight to Monitor Settings, in there again go to Advanced.

Under the advanced monitor settings you will find a tab called monitor, in there you find the monitor frequency. Try setting this to 50Hz, if that does not work try 100 HZ, that is the output frequency of your TV. If you get unsupported frequency, revert value to normal.

I have Compaq d325 Microtower AMD athlon XP 2800+ 2.08GHz 256MB 40GB CDRW NIC XPP. I want to use a Haier HL32R as my monitor, but it doesn't seem to want to work. I tried using a VGA connector between...


Using the VGA connector is OK. But to get it work, please be sure that the video settings on your computer are adjusted properly:
The resolution of your HL32R is only 1366 x 768. This is the MAX resolution you have to set on your PC. You can also adjust the refresh rate to 60Hz.

Please let me know if it helped.

Good luck!

I want to use my television as a computer screen. How do I switch the television to proper mode?

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.

How do you hook up the tv to a pc? I have the cable but I cannot get the tv to recognize the pc?

You will want to make sure that your TV is set to the same input that you are using to connect your PC to the TV. From the PC side, depending on whether you are using a laptop or a desktop PC, you will have to change the output so that the computer will output to the correct connecter.

If you are using a laptop, there is usually an F key that will allow you to switch from the built in display to either an external device, or both internal and external. The F key in question will usually have an icon on it that will look like a monitor screen. Pressing that F key at the same time as your Fn key should allow you to switch the outputs.

If you are using a desktop computer you will have to right click on a blank spot of your desktop and choose Display Properties from the menu that appears. You will then choose the Settings tab, and then the Advanced button. This should bring up your graphic cards control program. Again, depending on what type of graphic card you are using you should see a tab called Monitor. Some graphic cards will also have special tabs with a heading like Display or something similar. On this tab you should then be able to choose your output from the normal monitor you use to an external monitor. Your desktop will then start feeding the graphic signal through that output rather than the one you would normally use.

If this information doesn't quite resolve your issue please post another question but specify what kind of computer you are using, what type of graphic card you have, and what output on your computer you are trying to use. I will then be able to give you specific instructions for your setup.

If you are using your TV as a monitor, just hooking up the cables is not quite enough.. 1 make sure the cables are plugged in 2. make sure the TV is on the correct input since your using HDMI Select the correct HDMI Channel on the TV. Now its going to get a little tricky because I am not sure what OS you are using on your computer,. Now anywhere on your desktop where it is free, so not on an icon or anywhere with in an internet explorer window "Just on a blank spot on your desktop" you need to RightClick you will get a box with view , open, and a few other options. Go to the bottom usually personalize or properties.. Next select display you should get a connect to new display and for best results you want to extend desktop left or right, if you have the option left or right, if not just extend desktop. Make main or use secondary this means do you want your TV to be the main desktop, or your computer. after that make sure to correctly set up the resolution, your computer should do that for you automatically... Hope this helps you out..

I have connected my old dell laptop to this TV with VGA cable and audio cable and it worked with no problem. Have new Acer Aspire one netbook- connected to computer with same cables - can see windows...

First, you want to make sure the laptop's internal/external display mode is set properly. On Acer netbooks, this is usually changed by holding the "Fn" key, and pressing "F5". Either the TV or the computer display should flicker when you do this. There are 3 modes:

1 Computer only
2 TV Only
3 Computer and TV

If changing between thos emodes doens't work, continue on.

I am going to assume you are running Windows XP. Please correct me if I am wrong.

To display your desktop on an external monitor, you'll need to change/check some settings. Your netbook is most likely attempting to set it's display settings automatically, but it is expecting a computer display, not a television, so the resolutions and refresh rates are conflicting. That's why it will only display on one and not the other. Before Windows loads, the netbook is using a very low resolution,so it displays on the TV. Once Windows loads, it switches to some non-standard resolution that your TV cannot display and defaults back to your netbook screen.

The solution is to find a resolution that your television will display:

1.Right-click the desktop, and then click Properties.

2.In the DisplayProperties dialog box, click the Settings tab.

3.Click the Display list and select your external monitor (..the TV. It will most likely be display #2).

4.Select the Extend my Windows desktop onto this monitor option.

5.Select 640x480 in the "Screen Reolution" section for Display #2.

6.Click Apply or OK.

Note: If you see the background change on your television, mmove your mous there to make sure it's working. If it DOES work, go back to the "Screen resolution" section for Display #2 and find the highest resolution your television will display

Connecting to PC

Hi Sarah, You may want to try lowering the resolution of your computer down first before connecting the 42PX5D. Since everything seems to be working except when you get to the desktop then your PC might be set to a resultion that's too high for the LG (am not 100% sure, but I think that LG's max res is 1024 X 768). Try to adjust your PC's resolution while still connected to a regular monitor, right click on any free/clear part of your desktop and click properties. Display Properties window will pop-up, click on Settings tab, adjust Screen resolution towards the left,trym lowest posiible, color quality, again lowest possible. Then hook it up to the LG. If desktop now displays in LG, do the same again but this time going up. Do it by increment and stop when LG screen goes blank. Press escape to go to setting prior to blank. Adjust color quality best setting acceptable to the LG. Good luck and hopes this work out for you. Regards.
