I put together a new PC, but I'm having a problem with the graphics. I only have integrated graphics from the core i5-4460, mobo has VGA out only which my monitor has.


Whether I use monitor A or monitor B, when I have the appropriate driver for the intel graphics, I cannot output at resolutions above 1024x768. It shows up as an option, but choosing a higher res and selecting "apply" makes the screen go black and the monitor says no signal.


~ It's not a driver issue, I've tried several drivers and know I'm using the right one.

~ It's not a cable issue, cables are in firmly.

~ Latest version of BIOS is installed.

~ It's not a problem of BIOS selecting the wrong graphics source at boot, I have no external GPU so it only uses integrated graphics.

~ It's not a monitor issue, I've tried with 2 separate monitors and they both have the same problem, although they work flawlessly with any other PC connected.

~ RAM is fine, I did Memtest and 0 errors.


I'm trying to figure out if the problem is with my motherboard or the CPU since the i5 I have has the integrated graphics. Those should be the only 2 possibilities remaining for me.


Any way of knowing besides simply buying new stuff and testing? I don't want to have to return and buy new CPU/mobo unless I know they're the problem. Thanks!
