hi i have a question, i tried to use hardware spi in a arduino uno board for a nokia 5110 lcd. when i used software spi it worked perfectly. but it doesn't display properly in the hw spi setup. the output is the one needed but the pixels are such that all the characters are stretched out. the crystal used is 8 MHz and can’t get it to view perfectly for any clock divider setting. is there any solution? thank you! 
In your post we're missing the link to the hardware used (although the display is quite common, I don't want to google the datasheet), the description of how you wired it and most importantly: your code and links to the libraries used.
