Strange display and startup issues...

Can someone help me figure out the issue with this mess that's driving me crazy, please?

When I'm using DisplayPort, sometimes the screen freezes; this seems to happen with certain games. I have a colored background that covers about 10/20% of the desktop, but the top of the screen remains visible, and the PC is frozen, so I have to force a reboot.

And I have another issue at the same time (I'm mentioning it because I think it might be related to the DisplayPort or the screen): if I start the PC without turning on the monitor, the PC doesn't boot. However, if the monitor is on, the PC starts up and everything is fine.

I suspect there might be something to do with the DisplayPort, maybe settings to adjust in the BIOS, things to enable in there? I assume the problem is related to the DisplayPort, at least that's my initial thought...

This happens since I switched to a 1440p screen (msi G272QPF E2). At 1440p, I have a 6700 xt, and it's the same graphics card I had when I was at 1080p. I did a clean install of the drivers using DDU in safe mode, but that didn't solve anything, and it's driving me extremely crazy because I can't find a solution to this...

    Hello,

    Most likely hypothesis (ranking)


    - DISPLAYPORT CABLE

    Even new ≠ good.

    The DP is extremely sensitive at 1440p / 165 Hz

    A limited DP cable may:

    Work at 1080p

    BUGGER at 1440p

    Create EXACTLY this type of partial freeze

    This is the number 1 cause in such cases.

    - FreeSync / VRR bug on MSI + AMD

    Very common on certain MSI + Radeon screens.

    - Deep Sleep / DP Hot Plug Detect

    The PC waits for the screen → the screen sleeps → boot blocked

    - BIOS / UEFI / Fast Boot

    Less frequent, but possible.

    THE MOST IMPORTANT TEST (before anything else)
    ➜ Change the DisplayPort cable

    MANDATORILY:

    Certified DP 1.4

    Short (≤ 1.5 m)

    Not the one supplied with the screen

    Reliable brands:

    KabelDirekt

    UGREEN

    Club3D

    MSI SCREEN SETTINGS (VERY IMPORTANT)

    In the OSD menu of the screen:

    ABSOLUTELY disable:

    FreeSync / Adaptive Sync

    DP Deep Sleep

    Auto Source

    HDR (for testing)

    Then:

    Force DP 1.4 if option available

    Set 144 Hz instead of 165 Hz (temporarily)

    CRUCIAL TEST
    Connect the screen via HDMI

    Even at 1440p.

    If no freeze

    If the PC boots even with the screen off

    Verdict:

    DisplayPort is 100% the cause

    STEP 4 – AMD Settings (quick)

    In Adrenalin:

    Disable:

    Enhanced Sync

    Radeon Anti-Lag

    Chill

    Leave everything at default

    Ok thanks for the response, I will try all that, but reassure me, this: Short
    (≤ 1.5 m) is not mandatory? Otherwise, it makes the search a bit difficult. Any particular cable to recommend?
