I use DVR_RDK with version 00.07.00.01 and test the output resolution for HDMI.

Currently I found the 1080i is the defalut output, and I try to modify the

DVR_RDK_00.07.00.01/dvr/app/src/omx_il_display_ctrl.c

if(xVideoOut == VOUT_HDMI0_LIVE)
{

......
pInfo->DisplayWindowWidth = 1720;

               pInfo->DisplayWindowHeight = 1040;
                pInfo->nDrvInstID              = OMX_VIDEO_DISPLAY_ID_HD0;
                if (gDISPLAY_ctrl.bNTSC)                        pInfo->eDispVencMode       = OMX_DC_MODE_1080I_60;
                else

.......

I change OMX_DC_MODE_1080I_60 to OMX_DC_MODE_1080P_30, and it fail to display.

My questions are

1). Is current RDK supported other resolution like 480P/720P/1080P ?

2). If yes, how to modify that correctly?

Great thanks for your comment...

Hello,

HDMI currently supports 4 standard modes which are listed in the HDMI user guide packaged with the PSP release. The four modes supported are 1080P60, 1080P30, 720P60 and 1080I60.

Regards,
Marc

Hello, Marc

You mean the four mode are supported in EZSDK or DVR_RDK ?

Would you mind to provide some example s about these? Thanks

Hi,

EZSDK and DVR_RDK both of them uses HDMI driver for display. Currently HDMI driver supports 4 standard resolutions. So EZSDK and RDK can support 4 standard resolutions supported by HDMI driver. We are planning to add many more VESA and CEA resolution support to HDMI in future.

HIi Medwin Tsai,

I tried with your changes but using 1080P_60 instead and I manage to get display on monitor. but using 1080P_30 no output on monitor, maybe monitor not support this resolution.
