Question about Televison & Video

1 Answer

I am trying to connect my laptop to the Polaroid LCD TV, as i would like to use the TV monitor as a computer monitor (my laptop monitor is broken). So I connect the correct wire to correct places, however there is no VGA signal, only when the computer starts, the TV monitor also shows the first picture - like "Microsoft, windows..." in dark background. however, when the laptop monitor starts to display the desktop with different items, then the TV monitor stops showing anything and just says - "no VGA signal". so how to connect these monitors that the TV could show the PC desktop, etc.?

The simple patch that I found (same problem) was to start by using any old monitor that I could borrow to set up my Dell Laptop.
After getting the Laptop booted on a regular monitor I right clicked on the desktop and went to properties then to the settings tab.
Here I found the dual monitor settings (#2 will usually be dis-abled by default.)
Click on #2 monitor and set the resolution to the lowest number (800 x 600 works well)
Then I clicked on "make this monitor my primary monitor"
As soon as I clicked apply the PC Windows screen appeared on the Polaroid TV screen

Earlier I had set the secondary monitor as "extend this screen to this monitor"
This also worked but I had to "drag the current screen to the right all the way off the
"borrowed monitor" until it appeared on the TV screen. The mouse pointer will be there also.
At first it took a little getting used to but in a few minutes I was up and running.
Hope this helps your situation

Make sure it is set to a low resolution say 800x600 to start with, also ensure you have the "Other" monitor, ie: TV, activated, "Extend the Desktop to this Monitor" and set to Spanned or Mirrored, under "Display Settings". Also turn TV off, then plug it in from laptop, then turn tv on, then start pc. Also ,make sure you have latest drivers for your card.

Watch movies from computer to tv


look on the back or sides of the unit. it should have a hdmi cable hookup, it will look like a monitor input, then you have to make sure you set the tv input to that. then you have to set your laptop to add another monitor to be able to use it.

Hooking up computer to philips 60pp935217 AV5 HDTV connector?


Hi Roger,

Initially, pls try lowering the screen resolution of your PC. This can be done at the Display Properties/Settings tab and then move the slider of the Screen resolution towards the left, Apply OK. In some instances, you need to also lower down the Screen refresh rates in the Monitor tab of the Advanced Properties.

If your concern has not been corrected after completion of the above procedures, then other methods can be considered.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
