In general, your issue sounds like a "video display" problem.
Changing, not just "turning off", hardware acceleration inside of Office may help.
Changing hardware acceleration in Windows may also help.
How to Make the Windows Desktop Work Well on High-DPI Displays and Fix Blurry Fonts on win 8.1
http://www.howtogeek.com/175664/how-to-make-the-windows-desktop-work-well-on-high-dpi-displays-and-fix-blurry-fonts/
<snip>
Upgrade to Windows 8.1
Windows 8.1 offers much improved display scaling for high-density displays. If you’re still using Windows 7 — well, you shouldn’t use Windows 7 on a high-density display. New laptops with high-density displays will come with Windows 8.1 — stick with Windows 8.1 and don’t try downgrading them. Windows 8.1 can be configured to work much more nicely on a desktop system and has much better support for high-DPI displays.
Control System-Wide Display Scaling
To access this setting, right-click the Windows desktop background and select Screen resolution. Click the “Make text and other items larger or smaller” link in the Screen resolution window and you’ll be able to set a custom scaling level for your display.
Fix Blurry Fonts in Specific Applications
Many third-party desktop applications have blurry fonts when scaling is used. Windows 8.1 enables DPI scaling for all desktop apps, and ones that aren’t high-DPI aware will have blurry or fuzzy text, especially when they’re blown up to 200%.
To fix this problem, you can disable display scaling for specific apps. To do so, right-click the desktop application’s shortcut and select Properties. If the application is on the taskbar, right-click the taskbar icon, right-click the application’s name, and select Properties.
Click the Compatibility tab and click the “Disable display scaling on high DPI settings” checkbox. After you do, close the application and re-open it.
Fonts will no longer appear blurry in the application, but graphical elements will likely be much smaller. This is a trade-off you’ll have to make. Depending on the program, you may be able to enlarge fonts and other graphical elements in its preferences window to make them appear larger and compensate for the loss of proper scaling,
You could also just disable DPI scaling system-wide by selecting 100% scaling in the control panel screen above. If you did this, everything would appear smaller. Whether this is acceptable depends on how pixel-dense your screen is and how good your eyesight is.

Fix Blury Font
<snip>
I needed to disable display scaling on high DPI settings.
Normally, this would be very simple. You just:
· Right-click on your PowerPoint shortcut, and select Properties
· Go to the Compatibility Tab
· Check the “Disable display scaling on high DPI settings” checkbox
· Click OK / Apply
· Relaunch PPT
Presto ackgr, problem solved. However, PPT15 is a 64BIT application, which means that these checkboxes are grayed out and cannot be changed from this UI.
The only solution I found was to edit the registry manually (caution: this is generally a very dangerous thing to do, so be very careful with this)
· Type Windows Key + R to open the run dialog
· type “regedit” and click OK
· Expand the tree to HKEY_CURRENT_USER > Software > Microsoft > Windows NT > CurrentVersion > AppCompatFlags > Layers
· Click on the “Layers” node in the tree
· Right-click in the right hand side of the window (where it says Name / Type / Data) and select New > String Value
· In the name of the key item that is created, enter the location of your POWERPNT.EXE file (mine was “C:\Program Files\Microsoft Office\Office15\POWERPNT.EXE”) and hit Enter
· Now, right click the key that was created and select Modify
· In the Value Data text box, enter “~ HIGHDPIAWARE” and click OK
· Close the registry editor, and try reopening PPT
If your problem was scaling on high DPI displays, the problem should be solved.
To confirm that you edited the registry correctly, follow the first set of directions above to view the compatibility settings of PowerPoint in the UI. The checkbox will still be grayed out, but it will now be checked.

Finally I’ve found the solution... (it’s not perfect though... but now I am using Office 2013).

What to do:
“After you apply your desired font size in windows settings (like 125% dpi, I use this with 125%) > Open notepad, paste this into it:
Code:
REG ADD “HKCU\Control Panel\Desktop” /v DpiScalingVer /t REG_DWORD /d 0x00001018 /f
REG ADD “HKCU\Control Panel\Desktop” /v Win8DpiScaling /t REG_DWORD /d 0x00000001 /f
REG ADD “HKCU\Control Panel\Desktop” /v LogPixels /t REG_DWORD /d 0x00000078 /f
then save it as <yourname>.cmd somewhere on your HDD > open local ground policy editor (gpedit.msc from search bar) > In user config (im translating this from my language so there might be little translation differences) > go to Windows Settings > Scripts (login/logout) > In the window on the right double click on Log in to open it (because we want this to be applied every time you login) > in Scripts tab, select Add > then in new window select Browser > navigate to where you saved your cmd file and select it > then just press Ok > Apply > Ok > Then sign out/reboot your pc > Log in to your account for the first time after adding this script so it will be applied > then if it will not work, Sign out/reboot again and from now on it should work every time (works for me).
I noticed that fonts are much more crystal clear everywhere now, it seems MS messed up badly with dpi in windows 10... In some places font is only 5~10% blurry (right mouse click menu, display settings etc.) while in others (device manager for example) is 100% blurry. After this I have crystal clear fonts everywhere :3”

November 18, 2013 ‘Blurry fonts’ bug KB 2670838 persists with IE11 and Windows 7

Blurriness or distortion on newer NVIDIA graphics cards
http://office.microsoft.com/en-us/access-help/office-2013-known-issues-HA102919019.aspx
If you turn on the Manage 3D Setting on AntiAliasing – FXAA option for newer NVIDIA cards, you’ll see distortion or blurriness. This option is off by default because the option states “enabling this setting global may affect all programs rendered on the GPU, including video players and the Windows desktop.”
Workaround NVIDIA has released a newer driver that you can download from the NVIDIA website.
Or since the above setting is global, you can click the Program Settings tab of the Manage 3D Settings and customize your Office programs to turn the global setting for Antialiasing – FXAA to off. By default, the Use Global Setting is the setting and will take whatever is set globally.
Turning off hardware acceleration also fixes the issue but we don’t recommend doing this.
NVIDIA App
When you install GeForce Experience from NVIDIA, you will be notified about updates as well and allows you to update the driver from within the application; http://www.geforce.com/geforce-experience
Win 8 Enable ClearType Optimization
**http://www.insideris.com/windows-8-tips-enable-cleartype-optimization/**
Explanation
**http://answers.microsoft.com/en-us/windows/forum/windows\_8-performance/blurry-text-in-windows-8/ed053d17-b525-4e09-bdbc-de91114d975c**
The cause for Office, Modern UI and IE10 to look so bad is that they use a new graphics rendering API offered in Windows 8 (and with updates on Windows 7, too).
The new font rendering engine offered by this new API simply doesn’t have Clear Type implemented. So unless Microsoft patches this new API to support Clear Type, no program using this API will ever be able to do so.
The reason why Firefox (and Chrome, to an extend) are able to use Clear Type is because they still rely on the old Windows font-rendering API.
This is a bad decision by Microsoft, but their reasoning behind that (from what I think) is also quite clear: It is based on the assumption that their future will be in the tablet market. Since ClearType only works in one direction (horizontally, that is), it is totally useless if you rotate the tablet. The other thing is animation: if you animate a Clear Type anti-aliased font, its boundaries will start to flicker. And since Modern UI is a lot about animations and transitions, this would offer a bad experience.
Last thing is the much higher ppi (pixels per inch) offered by tablet screens (>200ppi) in respect to computer monitors (mostly <=120ppi), where grayscale-anti aliasing is totally sufficient for crisp fonts.
· And the worst thing: the Surface has a display with only 148ppi! So fonts look crappy on their reference design tablet.
· The bad thing is: no one can help you with the font rendering problem. You’re on your own, as a consumer. For me that meant to downgrade back to Office 2010, ignoring Modern UI and all apps completely and ditching i.e. 10 (but hey, that’s a no-brainer, isn’t it?).
Yoga 13: Blurry text on Win 8 & Win 8.1
https://forums.lenovo.com/t5/IdeaPad-Y-and-U-series-Laptops/Yoga-13-Blurry-text-on-Win-8-amp-Win-8-1/ta-p/1459517
Symptoms
Customers whose Yoga 13 with preinstalled Windows 8 or upgraded to Windows 8.1 may see blurry text on their screen which could be very uncomfortable to some customers.
Diagnosis
There are many discussion all over the internet in regard to this matter. While we are waiting for Microsoft to address this issue, the problem can actually be resolved by changing some settings below.
Solution
. 1. Go to “Desktop” mode.
. 2. Right-click on “Desktop” and select “Screen resolution” option.
. 3. Now click on “Make text and other items larger or smaller” link.
. 4. A “Display” settings page will be opened. You can also directly open “Display” window by selecting “Personalize” option from Desktop context menu and then click on “Display” link given at the bottom of left-sidebar.
. 5. Enable “Let me choose one scaling level for all my displays” option and apply the changes.
. 6. Restart your system.
FireFox Blurred Text

some People used About:config options to fix the problem
It’s a known issue by now. I have the same problem after the 19 update, but when I disable Hardware Acceleration everything is fine. Click on orange Firefox button and then options > options > Advanced tab > General tab > and uncheck Use Hardware Acceleration When Available
This isn’t much of a solution since the browsing speed is affected quite noticeable.
*************
· set the gfx.content.azure.enabled to NO
· disable Direct2D by setting the gfx.direct2d.disabled pref to true
Note: for some people some bookmarks sub-folders content in the bookmark toolbar are totally glitched and became unreadable.
However, I think I’ve found the cause of this mess... it’s Internet Explorer 10! In fact the issue appeared after IE10 has been installed by Windows Update.
Try to uninstall it and the fonts in Firefox will be good again (hopefully Mozilla will fix this issue, though, as sooner or later we will have to update IE).
You can also try to uninstall Windows update KB2670838 if you have this update.
· **http://support.microsoft.com/kb/2670838**
If you tried all the available fixes in about:config and Options|Advanced|General to no avail, there’s one last thing to try. Get rid of the current Firefox in your system. That includes deleting the Mozilla folder from your Programs and from your User Application Data. Then down grade to a lower version of Firefox, such as 15.0, where the text in menus shows grayed out instead of smudgy. Then upgrade to the latest Firefox. This works n a Windows XP Pro 32BIT environment.
This next suggestions is a very long shot:
Office CTR: “Compatibility Mode’ and “Disable Display Scaling on High DPI Settings” Bad font rendering in Office 2016

Both these .exe files DO have a Compatibility tab under Properties and a “Disable display scaling on high DPI settings” option available.

<snip>Thank you for this pointer. Seems that this does, indeed, fix the problem (for me, at least).
For my setup (Windows 8.1, Surface Pro 3, Office 365 - Office 15) the specific instructions are few and simple:
- Go to C:\Program Files\Microsoft Office 15\root\office15
- Right-click on powerpnt.exe.manifest and change the permission so you can modify the file
- Right-click on powerpnt.exe.manifest and open with Wordpad
- Change the line
<dpiAware>True/PM</dpiAware>
to
<dpiAware>False/PM</dpiAware>
5) Save file
(at least with Office 365, you don’t need to do anything in the registry as it’s already looking at the external manifest file.)
Yes, line 4 seems counter-intuitive, but it’s correct. Once you change this to False, Powerpoint will scale moving from high to lower DPI monitors. I’ve not encountered any other issues, but I’ve not used it for very long, yet.
Thanks to the previous pointers/authors for this tip.

PPT Scaling Across Multiple Monitors
<snip>
I followed these instructions and was starting to despair when neither disabling the DPI scaling nor changing the pointer to mouse made a difference.
I was having the same issue in Power Point with the giant ribbon extending my desktop across a pair of Samsung S27E450 monitors.
To resolve I called my help desk and they walked me through these steps which worked and now power point looks normal on my external monitors.
- Go into display settings
- Choose one of the monitors that you was extending to - which is the main monitor for me
- Scroll to bottom and choose Advanced display settings
- In Multiple Displays - choose Extend desktop to this display
- Choose the right resolution for the monitor - listed as (recommended) by Windows
- Hit apply
- Save the changes
- Go back to advanced settings for that monitor - Look for a request to log out next to the Multiple Displays
- Log out
- Log in
- Start Power Point
Hope this helps!

Use Windows 10’s individual display scaling to perfect your multi-monitor setup
**http://www.pcworld.com/article/2953978/displays/use-windows-10s-individual-display-scaling-to-perfect-your-multi-monitor-setup.html**
Windows 10, like Windows 8.1, includes an option to adjust the DPI (dots per inch) scaling on a per-monitor basis using a percentage scale. This wonderful tool gives you more granular control when you’re using monitors of varying resolutions, rather than applying a single DPI scaling percentage to all of your monitors—which can result in nasty sizing wonkiness—as older versions of Windows did.

2017 05 19- Improving the high-DPI experience in GDI based Desktop Apps
https://blogs.windows.com/buildingapps/2017/05/19/improving-high-dpi-experience-gdi-based-desktop-apps/
In recent years, High-DPI displays have become common. Having a lot more pixels to display your application on seems like a simple recipe for crisper graphics but, counterintuitively, the opposite is often the case. Many applications were written without taking the DPI of displays into account and are not able to natively render their contents on High-DPI displays. The visual elements (e.g., text, images, icons) of these applications will appear blurry.
GDI was for many years the de facto win32 2D API and is behind many of these older pre-high-DPI applications. GDI is used by applications to render graphics and formatted text on displays and printers. Beginning with the Creators Update for Windows, we have added a new feature, called GDI Scaling, that allows GDI to natively scale visual content on behalf of DPI unaware applications. Visual elements, especially text, can appear much sharper for these applications when this feature is enabled.
In this article, we will describe the challenge presented by high DPI displays, show you several ways to configure GDI Scaling, discuss how GDI Scaling works and give instructions to developers on updating their apps to run with GDI Scaling. While consumers and IT professionals may find this discussion informative, the primary target for this article are developers wanting to understand how best to make legacy GDI apps look right on high DPI monitors.
2017 04 04- High-DPI Scaling Improvements for Desktop Applications in the Windows 10 Creators Update
https://blogs.windows.com/buildingapps/2017/04/04/high-dpi-scaling-improvements-desktop-applications-windows-10-creators-update/
As display technology has improved over time, the cutting edge has moved towards having more pixels packed into each physical square inch, and away from simply making displays physically larger. This trend has increased the dots per inch (DPI) of the displays on the market today. The Surface Pro 4, for example, has roughly 192 DPI (while legacy displays have 96 DPI). Although having more pixels packed into each physical square inch of a display can give you extremely sharp graphics and text, it can also cause problems for desktop application developers. Many desktop applications display blurry, incorrectly sized UI (too big or too small), or are unusable when using high DPI displays in combination with standard-DPI displays.
In this post, I discuss some of the improvements introduced in the Windows 10 Anniversary Update that make it less-expensive for desktop application developers to develop applications that handle high-DPI displays properly.
