RE: Custom Resolution Utility (CRU)
@ToastyX, thank you for this great piece of software. I recently encountered a strange anomaly and I was hoping you might be able to help me with it.
I have OCed my monitor using CRU from 60 Hz to 80 Hz @1920x1080. I currently have the monitor connected to my VGA (HD 7950) via HDMI. I also have an intermediate refresh rate of 75 Hz which I use for desktop, since 80 Hz will result in a too-low value for vertical blanking and will not allow memory clocks to go down as mentioned in the opening post of this thread. For games that do have a refresh rate option, I set the refresh rate in the game to 80 Hz, but always keep it at 75 Hz for desktop. What I noticed recently after starting to use the monitor speakers instead of headphones for audio output is that in games, as long as I set the refresh rate to 75 Hz or below, audio comes out from the monitor speakers, but if I set the refresh to 80 Hz, the audio from the monitor stops and automatically switches to the sound card on the motherboard; in this case, I can only hear the audio if I connect a headphone/speaker to the sound card. I have so far tested and confirmed this in two different games. Any idea what is causing this and if there is any work-around? Please note that I created the custom resolutions with CRU a long time ago and have been importing from my CRU backup after every new driver installation (maybe I need to recreate them?). I am currently using the AMD Crimson Driver v17.6.1 (same thing also happened with v17.5.2). My OS is Windows 10 Anniversary Update. |
