screen flickering at 60Hz/ cant use dvi cables to go to 100Hz or above

[tacostand69]

im using a vga cable at the moment because its the only cable i have that works without completebly breaking my monitor but it still flickers at 60Hz, when i use my other dvi cables (including the one that came with my 144Hz monitor) at anything above sixty and i turn my monitor off and turn it back on i cant see anything except whole screen artifacting and tearing and what looks like the effect of an old fashion tape burning.i would like to know how to fix both of these like if theres a cable i need or something i dont think its my gpu but im no expert. any help would be appreciated thanks

What GPU is it? What monitor? What OS?

 

[tacostand69]

MSI GTX 970, benQ xl2411z, windows 8.1 64bit

Ok. Did you install monitor drivers on your PC? If yes..

If you right-click the desktop and select display settings>display, what does it say the refresh rate is set to under advanced settings? And in Nvidia control panel too?

 

[tacostand69]

im on vga atm and i cant go above or below 60HZ it says 60 in both

Ok if you disconnect the VGA from the GPU then connect the dvi cable can you select it in the monitor settings (Menu/System/Display)?

 

[tacostand69]

i attached the dvi and took out the vga and the screen just started doing some heavy artifacting and flickering and burning up like it usually does so i couldnt do anything and had to put the vga back in

Does the menu on the monitor mess up as well? That should still display ok.

 

[tacostand69]

nope it just does the burning up thing and everything goes black with like a white wave going across the screen horizontally and the buttons under the monitor dont come up

Well then it sounds like an issue with the monitor. If it was a problem on the PC end the monitor menu would still probably come up. Have you tried turning it off and on when the DVI is attached?

Says this in manual too

"Connect the plug of the DVI-D Dual Link cable to the monitor video socket. Connect the other end of the cable (at the end with the ferrite filter) to the computer video socket. Tighten all finger screws to prevent the plugs from accidently falling out during use.

i have tried turning it off and on again and it still happens but i'll try that thing from the manual

 

[tacostand69]

so i've managed to get the dvi cable to work but it still flickers over 100Hz and i dont know if its still gonna do the burn up thing when i turn it off and on again

 

[tacostand69]

i dont know if this will help or anything but it says dual link on the cables but in the Nvidia control panel it just says connected by dvi - PC

Yeah you need a dual link DVI cable for 144Hz but if it came with a 144Hz monitor it should be one. Can you set it to 144Hz in Windows now? Or is there still no option?

 

[tacostand69]

there is an option on here but at 120Hz it flickers every couple of second and at 144Hz its just constant flickering and stuff

How many pins does your DVI cable have on it? See this pic..

[tacostand69]

its definitely a dual link looking at those pics

Ok. It should really adjust automatically thats the odd thing. It may take turning the monitor off and back on but thats about it.

Can you see the monitor menu with DVI connected? If you can, check color format is set to RGB in Advanced Picture settings, that DVI DL is selected under Input in System Settings. Also try toggling DDC/CI which allows or blocks the PC from controlling the settings.

You could even try resetting all settings if none of that works.

 

[tacostand69]

i've set it to sRGB because thats the only one thats close to RGB dunno if its ny different, i dont know where to go to do the 2nd option, and i've tried toggling DDC/CI off and i've reset everything and it still doesnt work.

also i turned the monitor off and on again and it screwed up again with the dvi still in it, it started doing the "burning up" thing again and i had to0 put the vga back in

Have you had the monitor long? I'd contact BenQ and see if they know of the issue. Even if its not under warranty they may have come across the issue before. It shouldnt be this complicated to get your monitor running.

 

[tacostand69]

i've had the monitor for about 1 and a half years and the problem started about 6 months after buying and i've decided to try and fix it again because i tried back then but no one helped, but i'll try to contact benQ

 

[Multipack]

Well see what BenQ say first. They may be able to give you a clue to the problem. It may just be a faulty monitor but is probably config issues.

 

[tacostand69]

yea i've sent away the question hopefully they can help me, thanks for trying anyway
