Hello, On inspiron 3505 playing UHD videos is not going to be very smooth that model uses a shared graphics card UHD requires a dedicated graphics card with it's own memory you cannot change the graphics in a laptop (in a desktoo you can) .with a shared graphics card a part of the system ram memoiry is reerved for graphics so there is less "processing power" available playing UHD videos might work but it will not be the full experience.
I'm using Dell Inspiron 3505, AMD Ryzen 3, 3250U processor ,Now 8GB +16GB ram installed, For Boot 1TB M.2 NVME PCIe SSD installed.
