OS: Win10

Graphics: Intel HD Graphics 4600

Monitor: Dell P2715Q (connected DisplayPort to mDP)


Every time my monitor sleeps and subsequently wakes up, all windows are resized (smaller) and moved to the top left corner of my monitor. Seems to be a common problem voice across the internet with most solutions pointing to editing the Registry. For example...



In this register tree:

there is at least an entry per monitor; I had a DELxxxxxxxxxx and an ACRxxxxxxxxxx one, and under the 00 node, there are two parameters to check out there:
PrimSurfSize.cxPrimSurfSize.cy and Stride.

These should match your current monitor.

A little below you should see these entries:

inside, you will also find under the 00 node, and those parameters pointing to the old sizes. Use the values from above, and also change under the remaining 00 node the ActiveSize.cx &ActiveSize.cy entries to match. Log off or restart and voila!

But here's my problem...I've only ever had one monitor (the Dell P2715Q) yet my Registry shows 12 entries:















How do I know which of these to edit? Fair to assume some of these registries are inactive?

I should clarify, it's when Windows puts the monitor to sleep I believe rather than a monitor setting. If I turn the monitor off and back on, there's no issue with the windows rescaling/moving.
