    cannot get cards to talk to the TV

    packhntr

      Good morning all.  I have just upgraded my desktop from a pair of Radeon 6970 cards to a pair of RX580s.  I also upgraded to a nice 32" LG monitor with Freesync.  I was using a 40" Samsung tv, but after a while it would start to hurt my eyes.  The system works very well!  Excellent picture, great for gaming!  I am having an issue with the cards not talking to the TV.  I want to still use the TV (relocated to a wall mount) to watch Netflix.  I was using a DVI-I to VGA cable with the old 6970 cards, but the cable will not work with the new RX580 cards...they have DVI-D and Display Port.  I purchased a DVI-I to Display Port adapter and nothing.  I checked the software to detect secondary display and it does not find the TV.  Not certain if I should get a Display Port to VGA or a DVI-D to VGA.  The TV has HDMI ports as well, but their audio cuts out frequently, hense the use of the VGA port.  Ideas?

          Hello packhntr,

           

          The video card DVI out cannot up convert to a monitor DP in using some adapters.  Those adapters should be able to do the opposite however, connect the DP out on the video card to a DVI-D on the monitor (if that is possible).

           

          Beyond that, you can connect the DVI-D of the video card to an HDMI port on the monitor.  The signal is identical, you just won't be able to pass any audio, but since you were already using VGA I imagine that is not an issue.

            I would suggest to purchase an ACTIVE Adapter which converts the DVI-D/HDMI/DP signal to VGA before reaching the Television or Monitor

             

            Try changing to a higher quality HDMI 2.0 cable from the RX to your Television. Many times the HDMI cable that comes with the Television works better than a 3rd party HDMI cable.

             

            In my opinion, HDMI is much superior than using VGA.

                For sure.  VGA is still an analog signal, that would need to be converted from a digital source (DVI).  You can get color mapping/image scaling issues and a host of other problems.

                 

                DVI to HDMI however is the identical signal and requires no adapters, just a cable with the respective ends.  DVI doesn't have the pins to port the audio signal however, so that is always lost.
