How to get resolutions beyond 1200 (vertical) on CRT/VGA monitors and 4600 graphics?

[ODi_G]

Hello,

I have a CRT monitor (Sony Multiscan E540), and a Gigabyte z87 motherboard with a 4770 CPU. When using integrated graphics (HD 4600) I have not been able to get resolutions beyond 1200 (vertical pixel count). I have tried several times the CustomModeApp included with the Intel drivers, but every time I try a resolution that goes beyond 1200 in the vertical end, the software tells me that "...bandwidth is beyond the capabilities of your monitor..."... which obviously is not correct, since when I use my ATI 4870 card, I can handle this monitor at 2048*1536 @ 60 and 66 Hz. I even tried another resolution: 1920x1440, which sometimes I use, and still this one cannot be achieved either with the CustomModeApp.

How can I tell the Intel HD4600 driver that the monitor indeed supports these resolutions?

Thanks

Thanks for joining the graphics community.

I understand you are connecting VGA monitor on HD4600 and trying to get 2048*1536 screen resolution.

Please bear in mind the Intel® HD Graphics 4600 does not handle high screen resolutions via VGA port, according to the link below the controller has been designed to work with 2k- 4k resolutions using the following video ports: DisplayPort 1.2 / eDP, HDMI and DVI.

Your graphics controller provides basic visual quality when connected to CRTs
