ADC resolution problem in ATmega32

[shahbaz.ele]

Dear all
I am using ATmega32 ucontroller.
my circuit just includes Analogue data acquisition via ADC and display it to 16x2 LCD.
ADC and LCD working fine,
Problem is that my ADC misses some values, like it starts from 0 then jump to 3, 7, 12 so on up to 1023. because its 10 bit ADC.
can anyone suggest me its solution, how it can show 0,1,2,3,4,... on (5V/1024)=5mv change.
Vref is 5V.

What is the input of your ADC?

Check Conversion delay.
