ADV7611 Data resolution ratio

Question

ADV7611 is configured to connect to Xilinx FPGA in SDR mode to collect Ycbcr data images External HDMI camera with data resolution of 1920 * 1080 * 60hz The captured image has a video resolution of 1920 * 540, which means the image has been stretched and the number of lines has been scaled 
 But I directly connected the HDMI cable to the PC, and the captured image resolution was 1920 * 1080 
 May I ask where the problem may be in this situation? Could you please help answer it, experts? Thank you very much！！！！

Hi, 
 Kindly note that, ADV7611 is not a scaler and it will output only what we give (Whatever format comes in is what goes out). 
 Please crosscheck your configuration against our recommended script at 1817.ADV7611-VER.3.0c.txt.zip 
 Also measure the V and H syncs on the output of the ADV7611 to verify they are the frequency and position you expect? 
 
 Thanks, 
 Poornima
