Handling a remote desktop with high DPI (dots per inch) can be very tricky under Windows 10 v1703. However, most DPI-related problems can be carefully mitigated.
Problems with high DPI values usually occur when connecting devices such as Surface Pro 3 and Surface Pro 4 with external monitors. When DPI problems occur, the taskbar, icons, text and dialog boxes appear very small or disproportionate. The DPI problem also occurs when you use multiple monitors with different screen resolutions. The Windows interface may also appear as fuzzy text.
Microsoft has described in detail the steps necessary to solve high IPR problems and most of these steps are optimizations. Before continuing and trying to solve the DPI problem, try to optimize the settings and see if the problem is solved.
Bad behavior is something that refers to the DPI abnormality, whether it is blurred display, torn screen or loss of quality. The scaling of the display is of the utmost importance here and the failure of this scaling is certainly a problem. DPI problems do not occur when you use the Surface Book in standalone mode, but try to anchor/unhook it to the remote desktop protocol and problems occur.
The problem is mainly due to changes in the interface and monitor hardware configurations.
One of the best ways to solve this problem is to disconnect before docking and connect after docking. This is because the Winlogon starts when the user logs in and notes the hardware configuration and sets the DPI accordingly. Many applications do not have an automatic real-time DPI detection feature.
When you change monitors, it is always better to create a new Windows session. Another thing that deserves to be mentioned is that you should remember to upgrade your Windows 10.
Treatment of DPI problems with simple monitors
Well, simple monitor situations are generally not so complex and connections are good without DPI problems. The only problem is a side effect of the Remote Desktop Protocol (RDP) session.
If you are using the RDP with a computer in your office and have logged out of the session. However, the next day, when you try to turn on the monitor, yesterday’s active session is still displayed. The only solution is to disconnect the PC.
Best RDP results with multiple monitors
You must choose to use the monitor and know which monitor you want to mark as primary. Usually, the best way to proceed is to choose monitor number 1 as .
Then try using the Microsoft Remote Desktop application preview instead of the MSTSC. Now make sure your Windows 10 is up to date and return to the baseline by disconnecting, configuring the hardware and reconnecting.
