No picture on Plasma TV when using s3720y

[grantstaley]

I'm trying to run the video from a HP-s3720y to a Panasonic Viera 42" plasma.  I have checked using a smaller monitor and the computer works fine.  It is connected from the VGA out on the computer to a VGA/DVI Adapter to a DVI/HDMI cable with the HDMI plugged into the plasma.  No picture, zip, none.  Maybe its a bad DVI/HDMI cable but it is not a bad Adapter as that checked out OK.  But I do not suspect the cable.  Any ideas?

Cheers

Try directly from VGA to a HDMI convertor and check what happens .

Do you have any suggestions for a VGA to HDMI convertor? The ones I've seen are very expensive and I wonder if installing a HD graphics adapter will produce better video output and also be more cost-effective.

Now the convertors will cost you but what you can try is, go to the store and check with any convertor (VGA-HDMI) which they have and if its working then you can try investing money on that or else the issue may be regards to the video card that you have.

There is no other ways to send signal thru cables? I seen VGA to HDMI adapters on sale. Description says, you can use this cable only if your graphic card support HD signal. Adapter cost 5 buks, it more reason to buy only adaptor. Is anybody knows more about this?

p.s.

I have same problem like topic starter.

thanks for link, but question is "how to choose the right one ", not  "where to buy cables?".

I was hoping that PCCABLES had a converter.  You just can't can't connect a VGA analog signal to HDMI which is digital.

Your PC is spec'd with a 160 watt power supply so that will rule out a discrete video card.

Something like this converter might work.  The PC's on board video resolution will limit the resolution to your TV.
