How to fix the TaxCalc display when the High DPI settings are set incorrectly

In some cases users prefer to change the zoom settings in TaxCalc rather than their display settings, However, if too radical a change is made to the Advanced Display Settings (High DPI Support) the TaxCalc display can become garbled.

In this case the registry setting that control the High DPI settings need to be reset. This can be done via the TaxCalc Configuration tool, or directly through editing the registry.

Using the TaxCalc Configuration tool

  1. Download the TaxCalc Configuration tool from the following link TaxCalc Configuration tool
  2. Make sure TaxCalc is closed.
  3. Run the tool. You should see the window below

  1. From the menu click on Reset HiDPI Settings, this resets the values to the default.
  2. Close the TaxCalc Configuration tool and open TaxCalc, it should now display as expected

Please Note: if the tool cannot be downloaded or run as above, then users may need to choose one of the other options to reset the registry values

Edit the Registry directly

  1. Open the registry editor (regedit)
  2. Browse to HKEY_CURRENT_USER\SOFTWARE\Acorah Software Products\TaxCalcHub
  3. Double click on the HighDpiScaleFactor entry and set the value to 1
  4. Double click on the HighDpiMode entry and set the value to 1
  5. Close the registry editor and open TaxCalc. It should now display as expected
