I am working on a HDMI video project by using z-turn board (with zynq-7010) with 2560x2160 resolution at 15fps. I am using Vivado 2017.4 tool to implement the design. Since Video timing controller IP requires video timing information, I searched online for video timing calculators which are generating timings for VESA video standard.
By using different video timings generators, I understood that video timings are different for VESA ans SMPTE standards.
I wanted to understand whether can we use VESA standards in Xilinx IPs?
Will HDMI Transmitter(SIL 9022A) supports Vesa standards?
Thanks and Regards,

If you are referring to Xilinx HDMI SS IPs, they are as per HDMI specification, means they follow VESA specs for video applications and SMPTE specification for HDMI audio applications. I will recommend you to refer the specification docs before developing solutions around custom resolutions.

Hi @kvasantr ,
Thank you for the information.
Currently for testing purpose am using ZC702 Evaluvation board. I need to test custom resolution (1280x1080@30Hz). Video path is TPG ->VTC ->Axi to video out -> ADV7511 -> HDMI.
I have tested the design for 1080P@30Hz and its working as expected, however if i set custom resolution (1280x1080@30Hz) in VTC and test, am observing video input is not supported in the HDMI display.
To calculate video parameters in VTC for custom resolution, I used video timing calculator ie https://tomverbeure.github.io/video_timings_calculator
If I test 1080P@30Hz using video paramters calculated using above calculator am observing video input is not supported in the HDMI display.
I wanted to know from where we can get video timings if we set custom resolution in VTC.
