Question "Out of range monitor"

[MetlinDesign]

So i just build my pc, and ive been having an issue, it doesnt happen often maybe once a day. But im running 2 monitors, one old one i got years ago a 720p 17 inch 60hz monitor and one new on 1080p 144hz monitor, the new one will randomly shut off and in a grey box itle say "out of range" if i hit the power on the monitor and turn it back on its fine for a while, the second monitor stays on and the pc doesnt do anything at all it stays the same, ik its not a heat issue cause my gpu never goes above 70c on full load and cpu never breaks 51c, i have scoured the net and cant find an answer. Please help.

sounds like a connection issue.
What types of cables are you using to connect the monitors ?

Im using a display port for the main 1080p and a dvi port for the second monitor

I don't know for sure but it might be caused by the analogue connection of the DVI-I. If you have DVI-D and using a DVI-I cable it might also be an issue.
Does this happen if you only connect the new monitor ?

Ive never tried it, i could test it for a few days and see if it fixes it. Thanks

So i tried withought my second monitor for a while, worked fine for a while so i hooked it back up luanched warframe, and hit alt tab to chek discord, and it turned my main monitor off right after. This all happened right after hooking my second monitor back up.

List the monitors make/model
Can't diagnose if don't know what they are.

Dell D2719HGF is the 1080p HP S1931 Wide LCD is the 720p

I looked at the specs of the monitors and the Dell one is really nice. Shouldn't have any problems but for some reason it is.
Do you run AMD software of Nvidia?
I am sure its to do with the 720 monitor. But that needs to be set at a fixed 60hz.
The dell one should go all the way down to about 35hz up to 144.

Since where I am now, I don't run a dual monitor system, but how easy is it in your software to fix the frequency?
Are you using any adaptors or just cable with no adaptors?

Yeah ive been running with just the new one and havnt got any of that issue in a couple days, so it was definately the old monitor. Thanks for the help

Nevermind, its still happening, only when i hit alt+tab

If the new one is still doing it when you are only running that monitor, I would have to conclude it is faulty.
Unless something is up with the GPU and it's drivers.
Maybe download new drivers and also download DDU - follow DDU instructions to the letter.

Can you check if Freesync / G-sink is turned on and just turn them off ?

 

[MetlinDesign]

Yeah its on i have it off now
