Can't run CSGO at 240hz with 2nd monitor plugged in.

[tenji]

So 2 days ago i bought the Dell Alienware AW2521HFL 240hz. Everything works perfectly fine and at 240hz, except for CSGO. My 2nd Monitor is the BenQ Zowie XL2411P @ 144hz. With it plugged in i can only run CSGO at 144hz. Checking it by entering the mat_info console command. When I plug my 2nd monitor out and start CSGO it runs perfectly at 240hz. I can even plug in my 2nd monitor after i launched the game and everything works fine. Is there any solution other than unplugging my 2nd monitor every time when I start the game?

CPU: i7-9700K @ 4.8 GHz
GPU: Gigabyte GeForce RTX 3070 @ 2050 MHz
RAM: G.Skill 16GB @ 3200 MHz

sounds like a setup issue, if ur new main is 240hz, then the 2nd monitor (benq 144hz) shouldnt have an issue

i have 2 different monitors, benq at 144hz as my main, 2nd monitor is a old 4:3 75hz, doesnt affect my benq in the slightest

Yes, other games work perfectly fine.

Could be. But CSGO is the only game acting up.

EDIT:
I found the Solution. I just swapped the ports of the monitors going into my graphics card. Make sure your main monitor is actually monitor number 1 and your second monitor is number 2. You can check that by going into the display settings on Windows 10 and then click identify.

EDIT NUMBER 2:
It didn't work apparently. I thought it did, but problem is still there.
