i hasve a nixeus vue 24 and it comes with hdmi 2.0. my pc(laptop) only has hdmi 2.0, no display ports. so i need to use 120hz. it is said that hdmi 2.0 can reach 1080p at 120hz, however, in my case, i can only reach 1600x900 to maintain 120hz, anything beyond is set to 60hz as seen by this gif https://gyazo.com/ab8597969413d75ec40d0e43c7c083c3?token=4f28528b51d348465a56ba9bb1a856b8

But if the HDMI port on the monitor is not HDMI 2.0, then you won't be able to do 144hz through HDMI

Which laptop are you using, are you sure it's output is 2.0 aswell?

1080p 144 Hz has been possible over HDMI since 1.3, just depends on monitor support. The Nixeus claims 1080p 120 Hz support over HDMI.

The monitor doesn't have HDMI 2.0 so it doesn't matter what HDMI 2.0 supports or doesn't support. However that monitor should be able to reach 1080p 120 Hz over HDMI anyway. Are you using a High Speed HDMI cable?

also hdmi can only go up to 120hz even hdmi 2.0

 

HDMI doesn't have any refresh rate limits, HDMI 2.0 is capable of 1080p up to 240 Hz. However your monitor does not have an HDMI 2.0 port.

 

As mentioned, try setting a custom resolution.

NVIDIA Control Panel under Change Resolution -> Customize (set 1920×1080 at 120 Hz, and use CVT Reduced Blank timing)

 

Or use the Custom Resolution Utility (use LCD Reduced Blank timing)

Can it handle it without chroma-subsampling? I had a TV that had to be set to YCbCr (set at 4:2:0) since it couldn't do full RGB or 4:4:4 at the full refresh rate (could only do RGB at lower resolutions or refresh rates.)

 

Also some monitors/TVs do not have their ports set to the max by default and have to be changed in the settings. Make sure it's not set to HDMI1.4 and it's actually running at 2.0

Having issues with a Corsair AIO? Possible fix here:

Spoiler

Are you getting weird fan behavior, speed fluctuations, and/or other issues with Link?

Are you running AIDA64, HWinfo, CAM, or HWmonitor? (ASUS suite & other monitoring software often have the same issue.)

Corsair Link has problems with some monitoring software so you may have to change some settings to get them to work smoothly.

-For AIDA64: First make sure you have the newest update installed, then, go to Preferences>Stability and make sure the "Corsair Link sensor support" box is checked and make sure the "Asetek LC sensor support" box is UNchecked.

-For HWinfo: manually disable all monitoring of the AIO sensors/components.

-For others: Disable any monitoring of Corsair AIO sensors.

That should fix the fan issue for some Corsair AIOs (H80i GT/v2, H110i GTX/H115i, H100i GTX and others made by Asetek). The problem is bad coding in Link that fights for AIO control with other programs. You can test if this worked by setting the fan speed in Link to 100%, if it doesn't fluctuate you are set and can change the curve to whatever. If that doesn't work or you're still having other issues then you probably still have a monitoring software interfering with the AIO/Link communications, find what it is and disable it.

Most monitors don't support chroma subsampling. The monitor's port is only HDMI 1.4 so it doesn't matter whether the laptop is 2.0 or not.

Didn't know that... why is this the case? Fundamentally a monitor and a TV are basically the same thing, do you know why they are different in this case? Does it just have to do with the signal processor? The panels themselves work exactly the same.

I should rephrase, most monitors don't support YCbCr (and therefore don't support YCbCr subsampling). Computers specify colors using the RGB model since that's how display panels are built; TV panels are no different although they typically transform the colors to the YCbCr model during transmission over the cable (and convert back to RGB after receiving).

 

It's a vestige from older times since YCbCr separates the image into brightness and color components instead of red/green/blue intensity, so in YCbCr if you just take the brightness component (Y) and ignore the two color components (Cb and Cr) then you'll just get the image in black and white. You can see this yourself if you have anything that can use Component video (green/blue/red RCA plugs), just plug in the green alone and leave the red and blue unplugged, you'll get the same image in black and white. This is (was) useful for transmitting a single image which is compatible with color and black/white displays without any conversion.

Just type 144 into the refresh rate box, set the timing standard to CVT Reduced Blank, and hit Test :) If the screen goes black for more than 5 seconds then hit Escape.
