Rebooted and launched 2 different games, but the refresh rate is sticking to 30hz at 4K.
Is there something wrong on the cable i am using? i am going with hdmi for this from Alienware R3 with nvidia gtx 1070 card.

3840x2160 @ 60 Hz requires HDMI 2.0 or a monitor that supports YCbCr 4:2:0. That monitor only supports 3840x2160 @ 30 Hz.

OP says that the limit for dual link DVI is 330MHz but I still need to use the patch to achieve 72Hz (178.2MHz). Did NVIDIA change this?

The dual-link DVI limit has always been 330 MHz. You probably need the patch for one of the 165 MHz single-link DVI limits.

But I have a dual link DVI and it still needs the patch

If your monitor supported dual-link DVI, you wouldn't need the patch.

Hey guys,

I'm having some thoughs of buying the ASUS VQ24QE 144hz gaming monitor but have a few concerns that I've have not been able to clarify.

I have a ASUS ROG laptop, the GL552VW, running with the GTX960M graphics card and the crappy Intel Dedicated graphics. My laptop only has HDMI and so I've read around that it's possible to achieve 120hz through HDMI ports but I've tested it a few days ago with and wasn't able to achieve this amount of hz. Does disabling the Intel Graphics makes it possible to use the CRU and the Patcher and then get higher refresh rates?

What do you guys suggest? Is there any type of solution? I'm am mainly trying to get 1024x768x120hz to play some CS:GO. Anything beyond that is welcome!

Thanks in advance. GJ with the patch develpment!

No, but Intel recently released a test driver that allows CRU to work on some laptops with switchable graphics: https://downloadcenter.intel.com/downloa...est-Driver

The VG248QE does not support 120 Hz with HDMI directly, but it can handle 1024x768 @ 120 Hz with an HDMI-DVI cable. The only problem is whether or not you can add a custom resolution with Intel.

Does THIS apply to other gaming monitors such as the BenQ XL2411Z or the AOC G2460PF? Thanks for the reply, I'll try to run my own tests and will give feedback!

Which of these two would be better to try this method with the monitor

https://www.pcdiga.com/cabos-audio-video...hdmi-dvi-3
And then use the dvi cable that comes with the monitor,

or

And try to connect it directly.

My Intel graphics software does have an option to add custom resolutions!

Thanks

That depends on the monitor. The XL2411Z actually defines 1024x768 @ 120 Hz in the EDID, so you shouldn't even need a custom resolution. Cheap monitors without scalers like the QNIX QX2414 can't handle lower resolutions directly. Most monitors should be able to do it, but you may need to add a custom resolution.

Either will work, but I don't like adapters because the cable tends to weigh them down and cause connection issues, although that shouldn't be a problem with a laptop sitting on a desk.

I could push the equipment to 121hz with LCD Standard (501.91 Mhz Pixel clock) - anything beyond that and the panel would go into power saving mode from the video cutting out.

I tried LCD Reduced and LCD Native in 2Mhz steps from 122-130Hz and saw the same results above. I guess ~500 Mhz is the limit for my equipment. Looks like I will need to nut up and buy another video card if I want to go any faster. Again appreciate all the insight and help!

G-SYNC monitors don't support in-between refresh rates. Try 144 Hz directly with the "LCD reduced" timing option. This is what the ASUS PG278Q uses to keep the pixel clock under 540 MHz.

Toasty - my apologies. I hit submit to a reply to this post months ago but it looks like it never went through. I tried the reduced setting as you suggested but the panel doesn't like it (black screen power saving mode message kicks in - had to hit F8 recovery). I appreciate the help and knowledge you provided.
