Weird displayport behavior

dealer of aces · August 16, 2018

So I sold my friend my old Dell S2716DGR and gave him a new still in package DP cable along with it. Everything works he's able to play games and activate g-sync. In the control panel we were able to change it to 1440p@144hz. At first the display settings -> advanced settings in the windows menu still displayed 60 hz but after reseating the cable it shows 143hz now. The problem is games are limiting him to 60 hz as if v sync was on. We've turned off v sync globally, we've disabled g-sync, and thoroughly checked the settings in several games. He lives in a very rural area in West Virginia and the closest electronics store is about 2.5 hours away. He's going to order a new cable but I figured I would pose this question to the forum first.

The GPU he's using is a new GTX 1080. The monitor is about 6 months old I purchased new and have used at 144hz with g sync since purchase so I doubt its the monitor.

Any advice is highly appreciated!!!!

you can check in the Nvidia Geforce experience if v-sync is activated there.

or in the Nvidia drivers itself if it is overwriting game settings.

in game the frames can also be limited without V-sync turned on.

Like some older need for speed games.

first check if you have the latest drivers, if not, you know what to do.

if you have the latest drivers check if the above mentioned settings are set somewhere.

I know the drivers are updated and I'm pretty sure that I asked him to check it but I don't remember specifying to check global settings. I'll do that and reply back here tonight once he's off work.
