You can go as high as you want in resolution (4k even). Remember the built in graphics run from the CPU and use your system ram. Your PC would be slightly faster and have more ram with a dedicated graphics card.
So, i can actually use a high resolution monitor, it just basically takes away from my ram instead of using a dedicated graphics card? My computer has 16gb's of ram, with an i5 8400 processor, would this be sufficient? I actually had a man from Dell tell me that an integrated graphics card would not work for photos.
