    small area of screen with less dpi

    drsantafe@inbox.com

      I have a Sapphire R9 280x Toxic.  Recently during games there is  a small rectangle of lower dpi on my screen-on a 21 inch monitor this looks like about 1 1/2 x 1 1/2 inch.   This is with both an HDMI cable and a DVI cable.  Is this a typical symptom of bad memory, bad GPU, bad capacitors or what?  Is there any way of testing the card to determine the source and potential fix for the problem?

       

      Thanks

          What OS and AMD driver are you using? I would try using an older/newer driver depending on the driver you are using at the moment.

           

          If you can provide a picture of screenshot of what you are describing, that would be useful.

            Thanks for your reply AMDMatt.  I doubted if it was a software issue as I have 3 identical Z800s I've moved the card across and 2 identical R9 280x cards. The problem only occurred on one of the 3 video cards and appeared across all three platforms...but I post the information below because you are right, it should be posted with any question.

             

            Be that as it may, I did notice that the square of larger pixels moved around between machines so I thought...maybe its the old slightly tarnished gold connector thing on the PCIe buss.  So I reverted to my 1980s technology, got out my pencil eraser and made the gold contacts shine.  Strangely it worked.  So the square went away.

             

            Thanks again
