Question Fix Video Stutter on Second Monitor

[SyCoREAPER]

CPU: i7-13700K (Overclocked)
Cooler: Corsair H150 Elite Caprellix 360mm
RAM: DDR4 G-Skill 4000Mhz (4x16GB, Gear1)
MB: MSI Edge z690 DDR4 WiFi
GPU: MSI Gaming Trio 4090 (Custom SuprimX vBIOS)
PSU: MSI MPG A1000G PCIE5

Primary: MSI MPG321UR QD (DP)
Secondary; HyperX Armada 25


Never experienced this so I don't know where to start. First time in many years I've had multiple monitors on my personal machine.

Issue: Video in browser gets stuttery (Movies anywhere, Hulu, Netflix, etc...) on Secondary while gaming. Game is only Shadow of Mordor so nothing intensive.
MSI is 144hz, HyperX 240hz

Things I've tried:

1. Turn off Hardware acceleration in browser
2. Set secondary to matching 144hz.
3. DIfferent DP port on GPU.
4. Made sure G-Sync is on for all monitors.

Ddon't know where to go from here

With Intel's platform, you are advised to have 2 stick of ram if you want to pursue higher frequency and high capacity of ram per stick.

What BIOS version are you currently on for your motherboard?

Did you use DDU to remove your GPU drivers, manually reinstalling with the latest drivers in an elevated command, i.e, Right click installer>Run as Administrator?

Try and bring both panels down to 120Hz and see if the issue persists.

DDR4 - Because it was so cheap at the time and they only had two kits left lol. 4000Mhz is the XMP on the package so I didn't touch the frequency or timings outside XMP 1. 4000Mhz wasn't cheap either at the time and the 4 sticks was cheaper than two sticks and those timings (though not amazing) were better bang for buck than what was available elsewhere (was around when DDR4 just came out and there were PC parts shortages everywhere. System is 100% stable with 4 sticks.

BIOS - Latest. I told myself I wasn't going to do it but after not being able to get into the BIOS for a good 9-12 months it was a necessary step in troubleshooting.

DDU - Ever since learning about the tool that's all I use. To answer your question, the install is relatively minty. My key gave up (OEM?), bitched out Microsoft to convert my Windows 7 Ultimate key to Windows 11 Pro, they did that and I did a fresh install for sanity sake since it was Home Edition prior.
Drivers installed were the latest Nvidia drivers and currently are too.

Refresh - I'll try 120 later today, I find myself awake again and it's almost time to get up.

Sidenote, I saw a lot of people with similar issues while Googling the issue. For most it was matching the refresh but that was a year or two ago and could have been Windows 10.
