電腦安裝的是Windows10系統，近段更換了一個較大的顯示器，螢幕出現了字型模糊的現象。原因應該是DPI縮放的問題，設定一個較高的DPI縮放級別解決了字型模糊的問題。具體設定方法如下：
工具/原料
硬體：電腦
作業系統：Windows10
方法/步驟
Windows10系統螢幕字型模糊問題的解決方法
修改登錄檔鍵項解決Windows10系統螢幕字型模糊的問題。
登錄檔路徑：HKEY_CURRENT_USER\Control Panel\Desktop
步驟：
右鍵點選系統桌面左下角的【開始】，在開始選單中點選【執行】，在執行對話方塊中輸入：regedit命令，點選確定或者回車，開啟登錄檔編輯器；
在開啟的登錄檔編輯器視窗，展開HKEY_CURRENT_USER\Control Panel；
在Control Panel的展開項中找到Desktop（桌面），並左鍵單擊：Desktop，在Desktop對應的右側視窗中找到Win8DpiScaling（Win8 DPI縮放），並左鍵雙擊：Win8DpiScaling；
在彈出的編輯 DWDRO(32位)值對話方塊中，把Win8DpiScaling的數值資料從“0”修改為“1”，再點選：確定；
再在Desktop對應的右側視窗，右鍵點選空白處 - 新建 - DWDRO(32位)值；
我們把新建#1命名為：LogPixels（對數畫素），並左鍵雙擊：LogPixels，在彈出的編輯 DWDRO(32位)值對話方塊中，把LogPixels的數值資料從“0”修改為“96”，再點選：確定，退出登錄檔編輯器；
【說明：放大到150%，就填寫96，其他縮放比例和數值資料為：120% - 78，125% - 7D，150% - 96，200% - C8。】
登出一次系統，設定修改生效，則不會出現螢幕字型模糊的現象了。
在Desktop（桌面）新增LogPixels（對數畫素）鍵項，我們也可以複製以下內容到記事本中：
