Monitors Causing Games To Crash?

[VelizaBees]

So a few days ago I got two new monitors finally getting an upgrade to 144hz and for a bit I was loving them, but then when trying out random games to see differences and such, a few didn't want to open, from the current list that I know of being Terraria, Teamfortress 2, CS:GO, and Borderlands 2. I've tried methods to fix crash problems for all of these games aside from completely reinstalling steam of course (Rather not re-download games that do work if possible).
This is the monitor https://www.amazon.com/Samsung-LC27JG50QQNZA-Curved-Gaming-Monitor/dp/B07FBNNWVV/ref=sr_1_19?crid=2O5KTJ63I8ML&keywords=2560x1440%2Bmonitor%2B144hz%2B1ms&qid=1561332231&s=gateway&sprefix=2560x1440%2B%2Caps%2C155&sr=8-19&th=1
The only changes from memory at least from my computer since I last played these games (some of which I played right before switching monitors) is changing the hmdi cords to displayport and the monitors themselves.
TL:DR I think my monitors are messing up some of my steam games, not sure why.
Appreciate any help on this topic.

Test the old monitor with the new cables.
And the new with the old cables.

Try one monitor at a time.

What happens with those games anyway?

All of them besides terraria open a toolbar window for a few seconds and crash terraria doesn't even open

Even old monitor with old cable, so nothing changed?

It is unlikely that a monitor could do that.

What else changed?
What happens if you re-install an affected game?

I have a similar problem with Steel Rats, when i have 2 monitor's On the game have heavy fps's drop's and the only way to fix it is to turn of 1 of the monitor's Off directly on windows so i think it's not a problem with your hardware but probably the games it selves.

Check your GPU drivers and see if there is any driver's for the monitor on Samsung site.
(90% sure is a software problem)

Try reinstalling steam. I too just switched to 144hz and somehow multiple games started freezing after 5 minutes of gameplay, then the whole steam client would crash, so I deleted the steam, only left steamapps and installed it fresh. Now I just played for 30 minutes without the any freezing/crashing. I hope I fixed it for good. Maybe it was something with steam overlay thinking its still 60hz...

Turns out the last time I updated my Nvidia drivers it blue screened but the update finished so I didn't think much of it at the time but, I realized Geforce Experience wasn't opening so I reinstalled my drivers completely and all those games work thanks for the help to the people to responded!
