    Windows 11 PCs support Dynamic Refresh Rate (DRR) tech

    Microsoft thinks this will be a particularly beneficial feature for laptops, to save battery.

    Seems like a nice feature, providing the user has control over when/if it is enabled. These sorts of things have a habit of having a downside (often for a subset of users) though so being able to override what the system thinks is best, is a must.
    A lesson learned from PeterB about dignity in adversity, so Peter, In Memorium, "Onwards and Upwards".

    I thought VRR was already part of some VESA standard, at least for laptops. Isn't that what AMD based FreeSync on?

    Is this just Microsoft rebranding VRR as DRR or is there something fundamentally different.

    EDIT: Yea they did, it was back in 2014 and they called it ‘Adaptive-Sync’ and in 2009 for eDP.

    Does anyone organise their PC layout in a similar fashion to the article picture?

    This is just the branding for the glue in Windows that allows software other than games to support it. I guess as its not full screen windows needs to more involved than it does for a game.

    I've done split screen between two apps to make it easier to copy info between them but never tried 3! I suspect its useful on an ultrawide screen but little else!

    I thought eDP Adaptive-Sync already did that for the desktop, it was initially a laptop thing to save power IIRC. Unless this is on a per-app basis but then how does that even work, can a screen even have different refresh rates on different parts, like 30Hz for the top and 60Hz for the bottom?

    I guess Microsoft want to show of their better large screen support.
    As a proof of concept I made some snap to AutoHotKeys macros but haven't updated in ages.
    Basically trap CTRL+ALT+NumPad so that
    CTRL+ALT+1 is snap current window to left bottom quarter of screen,
    CTRL+ALT+7 is snap current window to left top quarter of screen,
    etc. using something like this:
    Code:
    stw1 := A_ScreenWidth /3
    stw2 := A_ScreenWidth /3*2
    sth1 := A_ScreenHeight/3
    sth2 := A_ScreenHeight/3*2
    
    shw := A_ScreenWidth /2
    shh := A_ScreenHeight/2
    
    ; ===================================================================
    ; = Display and Monitors 2x2 grid	    # Win ^ Ctrl + shift ! Alt =
    ; ===================================================================
    ^!Numpad1::	WinMove,A,,	0,		shh,	shw,	shh
    ^!Numpad2::	WinMove,A,,	shw,	shh,	shw,	shh
    ^!Numpad4::	WinMove,A,,	0,		0,		shw,	shh
    ^!Numpad5::	WinMove,A,,	shw,	0,		shw,	shh
    
    ^!Numpad0::	WinMove,A,,	0,		0,		shw*2,	shh*2
    ^!Numpad3::	WinMove,A,,	0,		shh,	shw*2,	shh
    ^!Numpad6::	WinMove,A,,	0,		0,		shw*2,	shh
    Should update and extend them to cope with multiple screens or even one key to apply something like this to the x most recent windows.

    Yes.

    My typical layout has outlook or visual studio in the middle, edge on the left with Jira/bitbucket/etc, and teams on the right. Sometimes that right hand side has teams + onenote stacked vertically if its needed.

    Ulltrawides are the future of monitors No more need for dual screens!

    DRR itself doesn't seem to be a "rebrand" or similar - this seems a neat feature if you can automatically enable/disable and scale DRR according to the apps your working with...nicer than a simple on/off!

    I guess it's the application of VRR to 2d apps/the desktop.

    I also guess we're still stuck at refresh rate on a whole frame basis? It would be nice to have it on a per-window basis (v. low for static desktop, high for scrolling windows etc.) but I presume the CRT model still has hangover.
