    HD 4850 Windows10 dual monitor boot issue


      Hi everyone,

      I have  a Windows10 dual monitor boot issue.

      Graphics Card: HD 4850 (good enough for 2D, since I gave up FPS gaming after 20 yrs or so...),

      • two DVI monitors
      • driver: 8.970.100.9001 (by AMD 01.13.2015.) windows downloaded this
      • win 10 Pro 64bit,
      • extended desktop

      Everything worked fine for a long while, but since the latest windows automatic update (build: 15063.608, no other changes in hardware, drivers) I experience this:

      BIOS boot : OK, mirrored on both monitors

      Win boot: under the Windows logo + spinning circle phase before the login screen the primary monitor loses signal and goes to sleep, the secondary is dark, but working.

      (Win boots from SSD in less than 10 secs, so this is not a time related issue)

      If (with no signal on the primary screen) I do a "blind" login, the secondary  monitor comes alive with the background, but still nothing on the primary

      If I unplug the primary monitor data cable and re-plug it, everything goes back to normal.

      Changing ports, cables, monitors did not solve the issue.

      I was advised to change to driver 15.301.1901.0, but it doesn't work for me, if I install it or later choose it under driver update , I end up with the MS basic display driver, so I have to opt back to 8.970.100.9001


      Please advise!

          That card does not meet the minimum requirements of Windows 10. You can change to Windows 7, or upgrade your video card.

              Alright then, why had it been working so far?

              I have been using this videocard with windows 10 ever since 10 debuted.

              Different configs, same videocard, same driver, dual display, a variety of monitors.

              No issues at all.


              So I bet the minimum requirements is not the root of the problem.

              Thanks for the reply anyway.

              Believe it or not, the very latest Windows automatic update (build: 15063.726) solved the problem, the previous one generated.
