MAA Posted February 18, 2019 Share Posted February 18, 2019 Hello, I have monitor BenQ GW2270HM As you can see in datasheet, Video Bandwidth = 205 MHz https://www.benq.eu/en-ee/support/downloads-faq/manuals/datasheet/monitor-datasheet-086.html and now i'm using mode 1920*1080@70Hz But, AIDA show incorrect info: Maximum Pixel Clock 170 MHz 1920 x 1080 Pixel Clock: 148.50 MHz Quote Link to comment Share on other sites More sharing options...

You can verify that information by checking the EDID details using other diagnostics software. Quote Link to comment Share on other sites More sharing options...
MAA Posted February 20, 2019 Author Share Posted February 20, 2019 I used DumpEDID, but i do not see "Maximum Pixel Clock" or "Video Bandwidth" info. How do you get this information (170 MHz)?

MAA Posted February 20, 2019 Author Share Posted February 20, 2019 DumpEDID shows not complete information? What simple utilities can show full info? Quote Link to comment Share on other sites More sharing options...

I don't know tools that would show detailed EDID information. There must be some, but I never tried to find them. Quote Link to comment Share on other sites More sharing options...
