HDMI Detective and Screen Size
Not sure what I did here, but I somehow messed up my screen resolution. I've been having handshake issues when switching to my HTPC from any other source, so I thought I'd try an HDMI Detective Plus. The first time around, it may have helped a bit as it would occasionally connect. So I figured I'd try programming it again to see if it would magically cure all my issues the second time around. After programming and plugging everything back in, I found the screen resolution to be too big and I cannot for the life of me figure out how to fix it.
I've tried removing the Detective entirely, programming the Detective again, and have gone through every setting I can find in my graphics properties, but I'm missing about half my taskbar on the bottom and probably about the same amount all the way around. I have my screen size set accurately in graphics properties. And unfortunately, none of the preset resolutions on the HDMI Detective match my display's native size.
My display is a Pioneer PDP5080HD, which has a native display of 1366 x 768, and for graphics, I'm using onboard Intel graphics. I've read about overscanning, but I don't know if that's the issue and I can't find any way to turn it off. I have found that if I set the HDMI input on the display to "PC Mode," it fixes the problem, but in PC mode I can't adjust my picture at all. Brightness and contrast are the only options available. Also, I'm not sure PC mode is what I'd want for cable or my PS4.
Like I said, everything was working fine, but somehow I messed it up and I'm pulling my hair out trying to figure it out. I seem to remember having a similar issue when I first built the PC a couple years ago, but I don't remember how I fixed it then.
Any help or advice would be greatly appreciated.
