Laptop repairs and upgrades

[HyperNGN]

Repair Issue: I got a laptop convertible the screen (just the glass touch screen) is broke the display itself is fine, I tried to download the manual for it for parts but the manual on has website for this computer keeps giving me the manual for models (model number 15-cn0xxx, 15-cn1xxx, 15t-cn000, 15t-cn100) which mine is a 15m-dr0011dx these models aren't for my model yet that's the manual it keeps downloading for my computers page on HP's website (http://h10032.www1.hp.com/ctg/Manual/c06297488.pdf) now I know it doesn't work because the manual shows the computers ram tops off at 16 gigs but when i run a max capacity using cmd it shows 32gig so I need the proper manual before I order the wrong parts

Upgrade Questions: 1. When replacing the screen glass i currently have a FHD Display now i seen in the (wrong service manual) that there was FHD and UHD is it possible to change the display and screen to UHD instead of FHD

2. I currently got a I5 intel cpu and i seen there is a i7 available with and without dedicated graphics cards my pc does not have a dedicated graphics card, and i know this is all in the motherboard so i was wondering if i can replace the motherboard that has a i7 and a dedicated graphics card to make the computer faster and so the UHD Display would work and if so would i also have to change the cooling system?

3. i wanna increase the ram to the max specs, my pc says 32 gig and the (wrong) manual says 16 gigs but i need to know if 3200mhz will work or does it need to be 2400mhz if the ram cant be overclocked (crucial shows 3200mhz as compatible)
