How to access max refresh rate of your monitor

[AJ Kenway]

I recently bought an ASUS VX239H 23.6 inch 1080p AH-IPS monitor. I'm currently running it at 60 Hz but the spec sheet says that it is capable of 75 Hz refresh. It also appears in CCC that the max reported refresh rate is 75 Hz but neither windows nor CCC allows me to access 75 Hz.

Here's the link for the monitor:

Can anyone help me resolve the problem? Do note that I'am running a 260X at 2.0 speed (planning to upgrade to the 370 or 370x when available if the price is right)

Would it work while running of HDMI?

Try it.

Even though it might seem in the setting that you're running at 75hz doesn't remove the fact that the max frequency an HDMI cable displays is 60hz. So you're seeing 60Hz instead of 75. You need displayport or dual link DVI cable to really enable higher frequencies.

HDMI should be OK for 1080p

That would mean over 5 gbps, so it will work only with a cable and port of hdmi 1.3 or above, so if your cable or port is not hdmi 1.3 u cannot access the 75 refresh rate.

Same with gpu and monitor interface.

Read the thread and calculate yourself for 75 hz.

My gpu has a DP port but my monitor doesn't have one. Should I use DP-HDMI or buy a HDMI-HDMI 1.3 and above?

HDMI-HDMI

I bought a HDMI 1.4 cable but it did not enable me to access 75Hz. Is there any other way to get 75Hz without overclocking the monitor?

DP-HDMI was the safe choice because u dont knwo what port your videocard has.

HDMI 1.4 If I remember correctly. I bought a 4K ready HDMI cable (1.4) but it still doesn't allow me to access 75 Hz. I tried to overclock the monitor but it outright didn't even let me to. I'll try to buy DP-HDMI in Japan. DP cables isn't available here in the Philippines, at least not that I know of.

If u say your hdmi is 1.4 dont bother to buy a dp, it wont make any difference.
