Faraway Desktop In-complete

I lately were given a Dell pc and I am putting in place for Faraway Desktop connection to my desktop PC.
Each are operating the similar model of Home windows Professional (20H2 19042.964) and all updates were put in.

Then again, when the desktop window seems on my pc, just a fraction of the desktop PC’s icons display up at the pc, and after I click on on one that does (Quicken, as an example), the app runs as whether it is logo new and now not initialized, and now not the usage of the Quicken knowledge report at the desktop device.

At paintings, I didn’t have this drawback operating between two Home windows Professional desktops (each machines are similar display screen measurement and magnification). In my pc case, the display screen sizes are other: 1920×1080 at the desktop (125% magnification) and 3840×2400 (300%) magnification. May this reason issues?

Additionally, I’m operating two shows at the desktop.

Any ideas on what could be happening, perhaps now not be setup correctly, and so on.?

Thank you
