Did you have your dinner?
侧重指过去有无这回事
Have you had your dinner?
说话人关心的是对方此时此刻是不是饿着肚子,因为现在完成时强调的是对现在的影响

did you 是对过去式提问，原句是 i had dinner
have you 是对现在完成时提问，原句是 i have had dinner
前者是问你有没有做过这件事，后者现在完成时是影响现在的动作，偏重于现在

前者强调过去吃饭本身是否发生，后者是现在完成时，指吃饭这个动作的有无对现在产生了影响

第一句中have为“吃”是对过去提问 第二句中have为助动词had为“吃”此句中have与had共同构成现在完成时的提问
