    Unsupported signal on Sony TV

    shaner25

      I bought a Dell OptiPlex computer with Windows 10 Pro and Intel HD Graphics 630.  When I first started up the computer, it worked fine to display on my Sony TV through HDMI.  After a day of usage, a series of Windows updates and Dell driver patches were applied.  Now, when I try to connect the computer to my Sony TV it always says "Unsupported signal, check device output".  I have used the Intel Driver & Support Assistant and it says that my Intel drivers are up to date.  I am using the latest Intel display driver.  What can be done to get my monitor working again?
