Greetings everyone, I have a monitor model Phillips 236V4LSB, that is set to work at 1920x1080 at 60hz.

I have extensively read about overclocking the monitor refresh rate in order to allow higher frame-rates, so I decided to set mine at 75hz and it worked flawlessly (higher values would begin to display blurry text on the monitor).

However, after I updated the Radeon drivers (AMD Radeon R9 270), it cleared my custom resolutions so I had to re-create 1920x1080@75. Unfortunately, now that doesn't work well anymore as the monitor displays blurry text.

I tried reverting the driver to the previous version in Device Manager but that didn't help. Do you have any ideas for troubleshooting? Perhaps I'm now creating the custom res with wrong parameters, different from the ones I had before? I'm using the CRU utility.

Thanks
