I am using Dell Vostro 5470 for a year.
I want to change its LCD Panel to have a better resolution.
Also want to have new lcd panel IPS and if possible matte screen.
Is that possible? I need assitance about that.
It depends on what you now have.
If it's a touchscreen system, you must replace the entire top half of the system -- not just the panel.
For any other type of screen, an increase in resolution means you'll need a new internal video wiring harness as well as the screen. Note that LCD screens are not all interchangeable - you are limited to those screens Dell shipped with the system. Other screens won't be coded into the system BIOS and won't allow a POST display, or may not produce a satisfactory image.
It is highly unlikely a budget model like this one ever shipped with an IPS display -- these are generally supported only by higher-end multimedia, gaming or mobile workstation class systems.
