Hi all,

I used to have both my monitor and my TV connected to my pc.
My old config was this: VGA cable from onboard VGA to my monitor.
VGA from my old graphics card (GeForce 8300 GS) to my TV.
(TV was used as an extention of my desktop)

In the Bios, I had the primary visual set to the onboard device in stead of PCIe.


Always worked like a charm.


I recently replaced my graphcard by a Radeon 4890 HD Vapor X.

Ever since, the resolution was on my monitor (from my OnBoard VGA to my monitor was giving a resolution of 1280x800 in stead of 1440x900, and it refused to budge in the control panel!)
Really weird, since this cable was untampered with.

So, I decided to change the BIOS settings from OnBoard to PCIe, and hooked up my graphcard to my monitor. Now the resolution was like it should, 1440x900.

Since I had to deactivate the OnBoard VGA in the BIOS because of resolution problems, I could no longer view it on my TV

So I decided to use my DVI-I of my graphcard, using this little converter to be able to connect my VGA cable to the VGA on my TV. (TV only has a VGA and a Scart )

Anyway, the TV is not recognized, and settings in control panels do not seem to be helping.


Should I be activating the DVI signal somewhere or what?

All suggestions are appreciated.

Since it connecting to a tv and not an actual computer monitor it may not be receiving a signal back from the tv letting the computer know it's connected.

Flip the two cables between the ports and see it it helps.

Thanks for your reply.

I already tried that, and the pc ran fine on the TV then.
But then the problem with the DVI was presented at the monitor.

Additionally, the TV used to be recognized before, when my old graphcard was hooked to my TV, while the OnBoard VGA was hooked to my monitor.


Anyone ?

btw,

When I plug in the DVI-I to the adapter to the TV, the control panel DOES recognize it as a second monitor, only the screen is not displaying anything.

It DOES display the normal pc screen when I plug in the VGA of my monitor, so the problem must lie with the DVI to VGA step.

I thought DVI-I was both a digital and analog signal so should have no problems with a VGA adapter, right?

It would appear to be a problem with the adapter itself possibly.

Which specific type of dvi is the "dvi to vga " adapter using? Because with my 5770 , it came with an analog only dvi-a to vga connector.

Another theory is that since your specific 4890 has four outputs but only support for two monitors , it may only support one vga/dvi monitor , while the second channel is reserved for the hdmi and "display port".
