Eh questions continue. So i bought the new monitor , now i have an issue. Then i set it to 144ghz refresh rate in Nvidia panel it starts to flicker/blinking and a lot of green pixels appear all across the screen. Any ideas ?
I’m using HDMI 2.0 port which is supposed to support up to 144hz.
Works fine in 60hz mode btw.
I have one theory so any of you nice tech savvy people could confirm it or deny it. This monitor only supports 144hz through HDMI 2.0 and i sort of doubt that my old GTX 970 has HDMI 2.0,probably some older version? Could it because of that?
Brief looking around it looks like a possible source of your trouble, possibly not though. The first gen of the 900 series did indeed not have HDMI 2.0, but the 970 should be 2nd gen 900s with HDMI 2.0 support being one of it’s upgraded features.
Now I don’t know if there might maybe be some manufacturers who made a 2nd gen card and cheaped out on the hdmi port itself or some such, not sure how one might go about figuring that out but maybe you can find something out searching out documentation on your card in particular.
Edit: MSI has the following to say about my own 970.
Not entirely certain how to interpret that information. Possibly it has 2 modes it can use depending on if you want to reach that 4096x2160 res it’ll do so in 1.4a mode at a measly 24hz and anything below that it’ll work in 2.0 mode. As it says nothing about the middle resolutions and higher frame rates, if you want to come over with your new monitor we could try it out. : )
Out of curiosity, if i remember correctly you also use GTX 970? Do you have 1440p 144hz monitor and does it work for u?Because i have found same vague hints in Dell forums that 970 is not capable of 144 hz.
Reading on in that wikipedia article however you’ll find a neat little table at https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video about framerates at different resolutions and HDMI versions.
Looks like we’re sitting at this uncomfortable space between two specifications where things are kind of possible kind of not. HDMI 2.0 can certainly do 1440p 144hz for standard video, but not for HDR10 video, in which case it requires some special “Y′CBCR with 4:2:2 or 4:2:0 subsampling” which I honestly do not know anything about.
Anyway, I would expect my own card to be able to pull off 1440p 144hz, but I don’t know for certain.
Some pixels turning green,flickering from normal to green, and it blinks to and out of black screen. Depending on other options i set in Nvidia Panel,like vsync mode or power options i can reduce or increase that blinking so it at least in my head is related to GPU .
I will try one thing tommorow, buying Display Port cable and see what effect does that have.
It kind of has a new symptom now. Previously it just flickered and went nuts but stayed on 144 , now it sets itself back to 60 after a bit.
Well i installed newest gpu drivers just in case ( also monitor drivers which seemed silly but who knows? ) and that didint do anything. Sadly this monitor only supports HDMI and DP so cant try my other connections like DVI or VGA ( I know they wouldnt support 144hz but just to see what symptoms are ) so i will go to some hardware shop tommorow and look for display port cable.
Any suggestions to which version should i look for?
I don’t know anything at all about these things, but i do remember that i once had an issue where i actually thought a Windows update had somehow damaged my monitor (i know i know, but im ignorant when it comes to stuff like this). It turned out it had something to do with these settings, if i remember right
I think i had to change the bpc or something and then it started working normally, while on another setting the monitor was completely messed up with green shit etc.
Well if DP wont solve the issue last thing i can think of to do is try to connect monitor to Dell laptop with 1050ti GPU which should be new enough to produce 144hz , if it wont treat it like a second screen and limit to 60hz or something like that.
