I have a Lenovo Thinkcentre M70E 0806 E1U and want to purchase a Viewsonic VX 2453 MH 24" LED monitor. Will the Intel graphics accelerator x4500 be able to handle/display the 1920x1080p resolution? Will I need to purchase a video card?
Yes it will - though the shared memory may rise a bit to cover the higher resolution, but most graphics cards can handle higher resolutions easily with no issues
You might have to set the resolution yourself if it doesn't automatically set it
