Question about Philips 200P4 (Silver/White) 20.1 in. Flat Panel LCD Monitor
I have a Princeton flat screen monitor with both DVI-D and VGA hookups. It works great when I hook it up to my laptop via a vga cable. However, when I use the same cable and hook it up to my desktop computer I get all sorts of weird bars and stripes on the monitor. (Note: The computer only has DVI port so I used a DVI to VGA adapter - this monitor has worked successfully in the past this way) Then I tried a DVI cable and hooked it up from the monitor to the desktop computer and got the same thing.
So I know that A) the monitor does work since it works with the laptop perfectly and B) The vga cable works since it also works hooking up the monitor to the laptop. and C) The problem is not the DVI to VGA adapter since I get the stripes whether I use a VGA cable with the adapter or the DVI cable directly
So now I'm wondering if something is wrong with the DVI card on the desktop? I am hoping I can try putting in a new DVI card (or vga card?) onto the desktop and get some more use out of it - even if it's just letting my kids play some games and simple web surfing.
Please let me know if anyone has a clue what to do. I am not technical at all but I wouldn't be afraid to try to fix it if it is cheap enough fix. I figure I have nothing to lose - am trying not to have to buy a new computer. Thanks for your help!

First of all you must check that your laptop supports a protocol called "DHCP" over DVI. Otherwise you are chasing your tail. This information will probably be in the manual or available online. DHCP is a special handshake protocol for HDMI and your television and computer will not talk to eachother without it. If you find it to be compatible you need to lock down which input on the TV it is. Plug something in via HDMI and verify you see it. Then unplug it and plug your computer into this port. You don't want to be flicking through inputs trying to find it. Also, hook up an external monitor to the laptop and figure what needs to be done to display on it. Then try the television. My guess, though, is that you won't find DHCP compatibility if it is an older laptop. My best advice is to buy a Playstation 3 and watch Netflix with that. Otherwise you'll need a different way of hooking up which might include buying an expensive converter box and/or watching poor quality video.

Your TVs sleep mode is activated. Disable it on your TVs menu under settings http://download.p4c.philips.com/files/1/190g6fb_00/190g6fb_00_dfu_aen.pdf also d/l new drivers for your monitor and install them.

For flat panel systems there are 2 inputs. DVI using the white cable and VGA. by default flat panels are set to DVI input. hit the menu button on the screen and there should be an option there to change the input video. if this will not work it could be a problem on the video port on your acer computer or it could you might need a new VGA cable.
