Trying to connect VGA to HDTV, no picture.

post #1 of 10
Thread Starter 
Laptop is detecting the connecting made with the TV but the TV has a black screen and I can't seem to get any picture on it whatever I do.

Laptops only output Laptops got is VGA out, so I am running a VGA to my TV which has a DVI so I ran a VGA to DVI converter for the TV.

All black screen on the TV no matter what settings I do on the laptop.

Have you tried lowering the resolution and refresh rate?

What type of VGA-to-DVI converter do you use?
You cannot convert with a (cheap) simple adapter. You need one of those little box converter (expensive!).

Eg:


Edit 1:-
DVI-to-VGA is easy and simple. But VGA-to-DVI is different. Ie if you want to connect the VGA output of your graphics card/laptop to a DVI input of a HDTV, this is not as simple.

I have used a DVI>vga adapter on TV's just fine.
Have you actually set your laptop to output to an external device also?

I don't really understand what you mean, can you explain?

I think I tried everything I can do from the laptop.

I don't want to spend to much money on this, currently I am streaming laptop -> 360 -> TV, but I want to cut out the 360 because my room gets really hot and I have problems streaming HD content with my laptop.

Let me give you guys more info. Laptop is Lenovo ThinkPad X61 (http://www.notebookreview.com/default.asp?newsID=3765) TV don't really know, but input is:

You first need to check out a few things with the TV. When you use a VGA to DVI converter, the signal is DVI-A (analog). does your TV accept an analog signal through its DVI connection, or just digital? DVI-A is analog. DVI-D is digital. DVI-I is both.

Next, once you confirm the TV will accept an analog signal, the adapter you got with the video card is more than likely, DVI>VGA. A DVI to VGA adapter, will not always work the other way (VGA>DVI). You will need to check your video card manufacturers web site to determine what type of adapter it is (VGA>DVI, DVI>VGA, or both)

I would try to connect it using a dvi to hdmi cable if your laptop has dvi output.
post #10 of 10
From looking at the tv input and laptop specs. You would need to check manual/specs on tv to see if analog input thru dvi wll work, otherwise run vga into a converter box to run the vga to the tv. It appears that if you have a dvi-a or dvi-i cable/adapter then it may work. If your TV had vga it would work fine even with an adapter or adapter cable.
