1080p on 23 inch monitor but text is blurry

Former Member

Dear raspberry pi gurus, recently I have just purchased a spanking new raspberry pi. I am tried to set the resolution to full hd which is 1080p 60 Hz. The config.txt that I had enabled was:

hdmi_drive = 2

hdmi_group = 1

hdmi_mode = 16 (1080p 60Hz)

hdmi_boost = 4

disable_overscan = 1

The monitor that I am using is 23 inch Dell Ultrasharp U2312HM. The pi is connected via HDMI to VGA converter (PI-VIEW) sold by element14. I have a steady 5V 1 amp PSU and I don't believe that the PSU is problematic.

 

I did the /opt/vc/bin/tvservice -s and it shows that my current resolution is 1920x1080, progressive. The only issue that I had is that the texts are blurry. Its kinda hard to read them, and is there any idea on how to make them sharp? I mean when I connect my PC via VGA mode, it still looks sharp on 1920x1080p. Please advice thank you

  • Check the monitor settings for something like 'auto adjust' or 'pixel clock' & 'phase' (all from my Dell 2001FP, may be different on yours). Some combination of those might help, but take a note of existing settings as you may have to change them back when you connect it back to the PC using VGA.

     

    LCD displays and analogue VGA connectors don't really go well together, use DVI if at all possible.

     

    There's some test pages and instructions for setting up LCD's and VGA connections here http://www.lagom.nl/lcd-test/ if you follow through  the pages there's a load of explanations of the issues.
