Picture quality

I know I got this during prime day at half price, but, am a bit disappointed in the picture quality. I am no tech expert but the picture quality on this Samsung looks washed out, grayish in color, colors don't POP. I have tried adjusting picture to no avail. It didn't come with a full manual so had to go online to try and figure out what adjustments might be made to bring color to full vibrance. Company coming soon and hopefully with their help maybe we can figure out. I suppose I can call Samsung for assistance, is that an option? Also, smart features seem smarter than me. Sometimes I get into something and cannot figure out to get out of it. I have another smart TV, LG, simple menus, easy to use and navigate, this one leaves something to be desired.
