[SOLVED] How do you tell if a monitor has a 2.0b hdmi port?

[forReese]

so the gpu I have now has 2 display ports that are defective, so I am forced to use the hdmi port, which until recently I thought locked your refresh rate at 60hz. I have a 144hz monitor so I want to get the most out of it that I can. I have been told that the gpu's hdmi port is 2.0b, and will support a 144hz refresh rate as long as the monitor has the 2.0b hdmi port also. Is this true? If so, how do I tell if the monitor hdmi port matches my gpu? If not, any other ideas? Really not trying to spend money on a new gpu but if I have to then I will. Thanks for the help.

What monitor? What GPU? HDMI 1.4 will support 1080p 144hz depending on the monitor, any revision of HDMI 2.0 will. I have never heard of a GPU with 2 defective DP ports. What did you do to it?

gpu is a 1080 FE. Monitor is Asus VG248QE. The whole reason I am asking is for some reason, my monitor will not receive a signal from my computer if I am using display port. I have tried both ports on the back of the gpu, as well as new cords and another monitor, still no change. The hdmi port is the only one that will work, so I am forced to use it for gaming, but I went into my games settings and the refresh rate is locked at 60hz. I have v-sync off, no frame rate limit and its in normal fullscreen, which is what I was using when the display port was working, and it would let me change from 60hz all the way to 144hz, but not since I changed to hdmi. I did nothing to my gpu to make it do this honestly. Its so strange because one day it was fine, the next day it wouldn't work in either port, but hdmi works fine.

The VG248QE is one of the oldest 144 Hz monitors on the market, it predates the publication of the HDMI 2.0b, 2.0a, and 2.0 specifications, let alone the implementation of them.

HDMI 2.0 support is not required for 144 Hz, despite what people may tell you. However, the HDMI port on the VG248QE is limited to 60 Hz regardless. Please see section 5 here: http://www.tomshardware.com/forum/id-3675170/connect-120-display-construction.html

The HDMI port on that monitor is 1.4 and only support 1080p@60Hz.

much thanks to all who answered. so just to be sure, hdmi 2.0 can support up to 120hz or 144hz at 1080p?

Yes, but there are only a few monitors that support 1080p@120-144hz with HDMI.

Are you sure it's the ports on the GPU and not the port on the monitor that is defective?

I do not know what else to try tbh. I have removed my gpu and set into new pcie slots, I have tried new cables, different monitors, reset my computer, uninstalled and reinstalled drivers, nothing has changed. Any new ideas?

Yes, and so can HDMI 1.4, but it is up to the monitor manufacturer to implement it. It is not really about version numbers, you cannot identify the capabilities of a monitor that way.

Again, read the link I posted, there is a list of all monitors that support 144 Hz over HDMI.

I was about to ask what are some monitors that support hdmi 144hz gaming, but thank you for the link!

 

[forReese]

ok so I checked those monitors that support 120hz+ over hdmi, but are there any more? I am severely ocd and need a lot of my peripherals to match lol. For instance, I have all corsair peripherals and both my monitors are asus. I wont even buy certain pc parts that don't match other ones, its that bad. Are there any asus monitors that support 120hz+ over hdmi? Or even MSI monitors? I have an MSI laptop so I wouldn't mind another monitor from them.
