HDMI resolution 1400x1050

Holger Eberhard102906

We use DVRRDK 03. / 0.4 and Udworks based hardware design.

I added some extra resolutions in Vdis_setResolution() for HDMI display output. For example I have append VSYS_STD_VGA_60, VSYS_STD_WXGA_60, VSYS_STD_UXGA_60, VSYS_STD_SVGA_60 resolution. The document 5826.DM81xx_DVR_RDK_Customer_Display_Resolution.pdf was helpfull for this.

I also want to add a setting for VSYS_STD_SXGAP_60 (1400x1050 60FPS VESA standard)

In linux/drivers/video/ti81xx/vpss/sysfs.h no settings are prepared for this resolution.

Is it possible to support this resolution ?

You will have to create display timings for this resolution. For example for SXGAP_60 below settings can be used

121750: display pixel clock(KHz)
1400: display width
88: horizontal front porch
232: horizontal back porch
144: horizontal sync width
1050: display height
3: vertical front porch
32: vertical back porch
4: vertical sync width
1: progressive output

#define VDIS_TIMINGS_SXGAP_60 "121750,1400/88/232/144,1050/3/32/4,1"

Timing settings work OK.

Thanks for the advice.
