| IDLE is blurry on High DPI Windows, because IDLE is not DPI aware. IDLE should be made to be DPI aware so that the text is more readable. |

| This is not an IDLE issue, and probably not a tkinter issue. The display of characters on a screen is done by the OS font software under direction of tcl/tk. What OS are you running and what version of Tk (see IDLE -> Help -> About IDLE)? |

| Westly, #31500 changed font scaling for IDLE on high DPI screens. It also removed some hard-coding of frame sizes in terms of pixels. Does anything look better for you with current IDLE (3.6.5, 3.7.0)? |

| Still blurry with 3.6.5 on Win 10 with a 2560x1600 monitor at 125% scaling (I compared it to 2.7.15, they looked identical). If I go to the Windows properties for pythonw.exe and turn on "Override high DPI scaling behavior" it's nice and sharp. |

| Do any of the Windows experts know what "Override high DPI scaling behavior" on properties does? Does it call SetProcessDpiAwareness? It seems so. The answer would have implications for #33656 (which is about fixing this issue in IDLE, as Westly originally requested here). This setting is on the popup when one clicks [Change high DPI settings] on the Compatibility tab. Eric, there is a dropdown with 3 possible overrides. Application (default), System, System [Enhanced]. Which one did you use? In my experiments, 'Application has the same effect as SetProcessDpiAwareness(1), while 'System' is the same as SetProcessDpiAwareness(0). I expected this from what I posted on #33656. Since the properties settings may or not be correct for all graphics packages, but will likely be correct for all tk and tkinter apps, I think tkinter should perhaps be modified. The question is whether SetProcessDpiAwareness(1) is correct (for tk and tkinter) for all monitors. I suspect so but don't know for sure. |

| I used the default Application setting. |

| Elisha Paine, who prompted #33656 by posting the SetProcessDpiAwareness(1) fix to the idledev list, wrote to me that pyglet and probably pygame have similar issues. I wonder if Python should be installed with the 'application' setting, or if DPI adjustment should be discussed in the Windows section of the Using manual. https://docs.python.org/3/using/windows.html |

| The fix for IDLE on Windows made it into 3.6.6rc1 and 3.7.0rc1. Changing the python.exe and pythonw.exe default dpi settings is a possible issue for 3.8, and should have Steve.Dower nosy. |
