SOURCE: Nvidia GeForce 7200 GS PCIE - Multi-Display does not work

This card does not allow you to Multi-Display with the VGA port and the S-video port. If you put a DVI to VGA port adaptor (not supplied) on the DVI port, you can Mulit-Display two VGA monitors and (presumably) a VGA (from the DVI port) and S-video monitor.

This is not explained anywhere and the card does not come with a DVI to VGA port adaptor, so I wa only able to work this out after I bought the DVI to VGA port adaptor.

SOURCE: no signal on HDTV

Your graphics card is probably too old to support HDTV signal (720p, 1080p)

SOURCE: HDMI port does not work on the KV-30SH420

I dont have a TV with HMDI input but i do have a computer moniter. To change i have to press a button that changes from VGA to HDMI. My computer supports HDMI and when i tried it, it works. Try looking in your manual for a way to switch input methods.

SOURCE: No Signal report by TV when connected to PC

Try changing resolution and refresh rates.  I have seen the same thing on Macs, and found that the TVs expect a 60Hz refresh rate and at least the Mac likes to use a 75Hz refresh rate.  When the two mismatched the TV would not accept a signal.  The easiest way to make the change is to use some sort of remote desktop login like LogMeIn.com or GoToMyPC.com.

I used to connect my tv with my laptop using an HDMI cable, and all of a sudden, it just does not work anymore. What can I do?


Hi Cyril Lott,

There is a possibility that the HDMI cable might have failed so try connecting another known good HDMI cable and check if that helps.

Thanks and Regards.

Sound output through hdmi


DVI is "Digital Video Interface". No Audio is transferred through this type of connection - even if one end of the cable is HDMI.

BEST solution would be to purchase a video card with HDMI output.

Alternate solution would be to run audio from rear audio jack to TV (assuming you have an input on the TV that will accept it)

Laptop to tv via hdmi cable suddenly stopped working


Maybe your tv's input is not set to hdmi. Also make sure you reboot the laptop. You might have to Press and Hold the FN function key at the lower left portion of the keyboard then hit the correct F1 thru F12 key that toggles the display. The correct key that toggles the display will have CRT/LCD on it or it might have the icon of a display.

I have bought a HDMI cable and I cant seem to get my Prosonic to work with my pc. It works on other TV's The cable works fine with dvd player. Is there somewhere on the TV I shall activate first? I...


How many HDMI Inputs are available on the TV? Also, are you trying to project your computer to the TV or get TV on your PC?
I will assume the first scenario. The only thing I can suggest is that if there are multiple HDMI inputs then you will need to choose the correct one to change it to. If it does not give you that option on the TV input switcher menu then you can try to plug and unplug (while everything is on and attempting to project) the HDMI cable into different inputs on the TV until you find the right one.
Alternatively you can use a VGA/DVI cable depending what is on the back of the TV and that will definately work, but won't be HD.
Hope this helps.

Connecting Ps3 with philips tv (full hd) when i got hd cable in, and click to switch so the ps3 uses hd to show things and i than switch over to the channel i plugin the hdmi cabel it gives blac kscreen


If it's the first time using your PS3, use the composite cables that came with it. Turn on the PS3 go to video settings and switch the input to HDMI. After you've switched to HDMI, turn the PS3 off and connect your HDMI cable, go back to video settings and change the resolution to 1080p. If this isn't the first time you've used HDMI for your PS3, make sure your T.V. is on the correct input. If the T.V. is on the correct input, try switching the HDMI cable to a different input. If that doesn't work try using a different HDMI cable, testing different HDMI connections if you're still getting the black screen. If none of those work then it's probably a problem with the PS3, but just to make sure try plugging something else with HDMI to see if that works. If another HDMI device works, then it's your PS3, if it doesn't then it could be a problem with your HDMI connections on the T.V.

I have a Proscan 40 inch 1080P LCDTV (40LD45Q), but when I connect my computer to it, (GTX 260) with DVI-HDMI cable, it says the native resolution is 1366x768. Is Proscan lying that this TV is 1080P?


You can attempt to force 1080p to the TV by unchecking the box "hide modes this monitor cannot display" in the display adapter propteries, then try to select 1920 by 1080p, 60hz, 32 bit color, and see what happens. Post back what your findings are.

How to tune in for blu ray dvd


You do not tune in your Bluray player but connect using an HDMI cable or Composite cable. If you have a HDMI cable connect the Bluray's HDMI out to the TV's HDMI in at the back and using the TV's remote switch the Input source to HDMI. You will see the image from the Bluray player in high definition.
If you don not have a HDMI cable connect the composite out of the Bluray player using the Yellow/Red/White cable to the TV's composite input ( same three color sockets ) and switch to AV input on the TV. Using this connection won't give you high definition image but will work OK.

My Philips 42PFL3603D/27 that does not connect to hdmi device.


At the rear or side of the PC there should be either or both of a 15 Pin DIN Plug, HDMI socket. or a Yellow RCA or 4 -7 pin DIN. Now IF these are present then YES you can connect to a TV. Now some TV's have a connector a DB15 MALE, so that the cable from the PC to the TV, is DB15. this plugs in directly, with appropriate DB15 cable. This, however, will ONLY take the VIDEO to the TV, Audio is delivered via the "Audio Out" Jack on PC, and Plugged into the AV Sockets on the TV, with a dual cored coaxial cable, they are Red & White. Some PC's also have a Yellow RCA Connector, OR a 4 -7 Pin DIN Socket, that requires a Special Adapter Cable (That generally came with the unit, and are colored and marked as to output) to use, for Video/Audio Out to TV. This signal is Composite or SVHS Video & Stereo Out. This connects up TO the TV's Composite/SVHS input Jacks and the Red & White Audio IN, RCA Jacks, &/or DIN SVHS socket.
First you need to know if your PC can output to a TV. Then you need to get the adapter & cables that connect the PC to the TV. Then you need the correct TV drivers installed for your video card. When they are all installed, you need to "Enable" that Monitors, the TV's, Desktop. You need to set either a "Cloned" display or "Spanned, Extended Desktop". Go to "Display Settings" Now ensure the TV/Monitor connected has the correct input/output display settings. Adjust the screens resolution via the resoloution "Slider", it is best to start with, 800x600 32 bit color. or even lower. and once working OK, THEN increase to max resolution, your TV can handle, find out from manual. Once it is all connected up. It should all just work great. Now, from then on, &, to get it to work every-time, the process is. Turn everything OFF. Connect the leads between PC & TV, Turn the TV, ON. Then, startup the PC up. It should "Detect" that it has TWO "Monitors" ie: One Monitor & One TV/Monitor, & you should see your desktop appear after a bit. Now you have screen 1 & screens 2. Now, if you are using "Cloned" mode, then whatever is displayed on the Master monitor, will be displayed on the TV. If you used Spanned, mode, in this mode, however, you will have to."Drag" the Video window, over to the TV, and it is though, you have one "Big Desktop". Now IF using Nvidia or ATI then BOTH of those have thier OWN, Control Panel, this, all then can make it all a lot easier to do it. So I would suggest that this method be used. But if you get stuck, or just want to do it by hand, then the the "By Hand" method is the only way.There is a great program called MultiMon, this allows great control over dual displays, and is well worth installing.
