[Dunkypuncb]

so i cant get any signal through the displayport on my 1080 ive already replaced the 1080 and diplayport cable ive noticed that my 10080 is running at 8x i have a sound card in the slot under it. would taking the sound card off possibly help the 1080? im desperate i have a brand new 1440p 144hz monitor i  can only use at 60hz .

8x won't bottleneck a 1080.

It Will, just very slightly. Id say a 3 fps decrease.

what motherboard do you have?

[Dunkypuncb]

check single card benches

im not worried about bottlenecks i just wanna know why i cant get signal through the diplayport outputs none of the 3 ports on the card will put out signal except for the hdmi and dvi. my 970 that was in the pc before worked fine through displayport.

[RUWO_builder]

You said you tried another 1080, right? Did Those ports work? Otherwise i'd rma the card

make sure the DP cable fully goes in, while the PC is still ON remove the HDMI cable from both ends FIRST then install the displayport cable.

well i got a msi gtx 1080 seahawk ek 1st got no signal through displayport and the second one thats in the pc right now is doing the same thing so i dont think its the gpu. both 1080s are the same model.

[Dunkypuncb]

nope still nothing

[Droidbot]

i'd say contact MSI, maybe the ports are broken. 

[Dunkypuncb]

on two different cards? well thanks guys in out of ideas i might rma the monitor or get me a ryzen systems when that comes out. thanks for the help

are u able to switch the default input on the monitors settings?

[Dunkypuncb]

yes i can get in the osd and switch between hdmi or displayport  but only hdmi will put a signal on the monitor

with only displayport connected try turning the monitor off fully (unplug power cable) then wait a minute and reconnect.

that shows a slight decrease running 8x lol  

 

which is about right, its like 2-3% on the best cards

well consider that the TX is faster than 1080, a slight decrease is to be expected with the top-tier card but it should affect the lower end cards less and less

Well it also depends on res and game, Ryse here (and WoW) all benefit quite a lot, and this is with a 980
