I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

I have a flatiron m1921a, every time I connect it to my pc, I get a no signal on my screen, what do I do please?


Hi,

Welcome to FixYa!

There are three reasons why you are encountering that problem, it's either the VGA cable, VGA port or the monitor itself. Please follow these steps for you to be able to isolate the exact problem.

1. Disconnect/Connect the VGA cable.

2.. Make sure that the VGA cable is properly connected

3. Try to use another VGA cable

4. Try to connect another monitor.

If you're already done with these steps and its still the same, most probably, the problem is with the VGA port. In that case, you will need to replaced the Motherboard itself.

Hope this information will help. Thank you for using FixYa.

My monitor is getting red color is there any solution


Hello !

Well, there is a problem with either your monitor, VGA cable or video card.

If you wiggle the VGA cable (the cable connected from your monitor to computer) and the color changes, the VGA cable is faulty.

Either connect your monitor to a different computer or connect a different monitor to your computer to see the results.

If your monitor works on another computer, your video card is faulty. If a different monitor works on your computer, then your monitor is faulty.

Hope this helps.

Monitor works but I have a single 8'' green line in the screen. Is there a solution for this problem?


Check the VGA cable (the one with the blue ends, with two screws at each end), one of the pins on the end of the cable might be bent out of shape, and is not connected. check all four ends, both male and female connections, at both ends of the cable, and the point where it connects to the PC.
if the VGA cable is hardwired to the monitor, you have half the job, and just need to check the end of the VGA cable, where it connects to the PC.

Computer in safe mode and monitor will go to sleep mode....help what can I do...my husband tried everything....


First, Shotdown your computer from start ,
then remove your computer power, remove VGA cable, remove VGA power cable. then
1- connect vga cable to computer.
2- connect VGA power but do not power on.
3- connect computer power on but do not turn on
4- turn on computer first and 3 second turn on your lcd.

if NOT try powering on computer then Monitor then power the computer then monitor.
IF NONE worked, YOU may have LCD that need drivers from manufacturing, some newer models required that, Specially for vista.You may use older Monitor to get drivers to computer and extracted, then you may connected, you will have solved the problem.
Goodluck

My emachine will turn on and run without doing anything. The monitor states no signal.


Either the VGA cable (cable from your monitor to computer) or VGA port on your computer is faulty. Try connecting another monitor to your computer to determine the problem. If the other monitor works, then your VGA cable is faulty. If the other monitor doesn't work, the VGA port is faulty. Hope that helps.
