How can I make Doceri show the whole Windows screen?

help

If you find that only part of your Windows computer display is showing on your iPad when connected to Doceri Desktop, there are a number of settings that may need to be changed to resolve the issue, depending on your particular combination of hardware and software. These are addressed step by step below, starting from the most likely cause that is easiest to change.

  1. Changing your zoom level in the Doceri app
  2. Changing Windows Display Settings: Scaling
  3. Changing Windows Advanced Scaling
  4. Changing Java High DPI Settings

Changing your zoom level in the Doceri app

The first thing to check is your Doceri zoom level. Try using the pinch gesture to change the zoom level in or out. Rotating your iPad a quarter turn and back (from landscape to portrait or vice versa) also should reset the zoom level to its natural state.

Changing Windows Display Settings: Scaling

When using Doceri Desktop on a Windows computer with multiple displays (and a projector counts as an additional display), the Scale & Layout setting for all displays needs to be the same, otherwise one of the monitors may be cut off when displayed in Doceri.

  • • Open Windows Display Settings. (See instructions from Microsoft Support.)
  • • As you click on the display images at the top of the Display window (see attached Windows Display Settings screenshot image), you will see current Scaling percentage for the selected display shown in the dropdown box (indicated with a red arrow in the screenshot) as a percentage.
  • • Click the Scaling dropdown box change any of those values as needed until all screens that will be used in Doceri have the same percentage.
  • • As the display changes, you may also find it useful to adjust the resolution setting in the next dropdown list control.

Changing Windows Advanced Scaling

If changing the scaling settings does not resolve the matter sufficiently, then it may be necessary to modify the Advanced Scaling Settings as well or instead. However, note that this change sometimes resolves the appearance of the screen at the cost of side effects such as misplaced clicks when Doceri is in control mode. We therefore do not recommend this step be taken until exhausing the previous options listed above.

  • • Quit Doceri Desktop. (See this brief video if you are unsure how to find the Quit command, which is different from Minimize.)
  • • Return to the Windows Display Settings screen from the prior step.
  • • Click the Advanced scaling settings link (highlighted in yellow on that attached Windows Display Settings screenshot image) on the Display window.
  • • On the resulting "Advanced scaling settings" dialog, under "Fix scaling for apps" turn on the “Let Windows try to fix apps so they’re not blurry” feature. See the Windows Fix Scaling screenshot image attached.
  • • Restart Doceri Desktop and establish your Doceri connection again to determine whether the issue has been resolved.

Changing Java High DPI Settings

The final option is to change properties within the Java environment on which Doceri Desktop is built.

  • • Launch Doceri Desktop if it is not already running.
  • • Open the Windows Task Manager. (See this WikiHow article for several ways to do this if you are unsure.)
  • • Right-click on the Task Manager process Java(TM) Platform SE binary. (See left side of attached Java Task Manager screenshot image.)
  • • On the resulting context menu, click the option for Properties.
  • • On the resulting javaw.exe Properties dialog (pictured on the right side of the attached Java Task Manager image), select the Compatibility tab.
  • • On the Compatibility tab, in the Settings section, click the "Override high DPI scaling behavior…" checkbox (highlighted in yellow on the screenshot) if that option appears, then select Application from the dropdown block immediately below the checkbox.
  • • Depending on your software versions, some systems will instead have a "Change high DPI settings" button on the On the Compatibility tab. If you have that instead of the checkbox mentioned in the previous step, click that button to reveal the same "Override" checkbox.
  • • After applying your change by clicking OK on the Properties dialog, Quit and restart Doceri Desktop, then and your Doceri connection again to determine whether the issue has been resolved.

If all of these solutions have been applied and your iPad still will not display the full computer screen, then you unfortunately have discovered one of the rare combinations of hardware that is not fully compatible with Doceri Desktop. We will be unable to resolve the matter further, as Doceri Desktop has been retired as of 2022-08-01.
