Welcome to Windows 7 Forums. Our forum is dedicated to helping you find support and solutions for any problems regarding your Windows 7 PC be it Dell, HP, Acer, Asus or a custom build. We also provide an extensive Windows 7 tutorial section that covers a wide range of tips and tricks.
Setting the DPI size to a smaller number or percentage will decrease all items size on the display, while setting the DPI size to a larger number or percentage will increase all items size on the display.
Typically, the higher the dots per inch (DPI), the better the fonts will look. If you set the DPI higher than 96, and you are running aWindows Aero theme, the text and other items on the screen might appear blurry in some programs that are not designed for high–DPI display in this version of Windows. You can avoid this issue by using legacy DPI scaling (Windows XP style DPI scaling) for these programs.
2. Right click or press and hold on an empty area of your desktop, and click/tap on Personalize. (See screenshot below) NOTE:The Windows 7 Starter and Home Basic editions do not have Personalize included in them.
A) Towards the bottom left corner, click/tap on the Display link. (See screenshot below)
B) Go to step 4.
3. Right click or press and hold on an empty area of your desktop, and click/tap on Screen Resolution. (See screenshot below step 2)

4. You will now see this screen. (See screenshots below)
5. To Select a DPI Size
A) Dot a size that you want for the Display DPI size. (See screenshot above)
Smaller - 100% = 96 DPI (Pixels/Dots Per Inch)
Medium - 125% = 120 DPI (Pixels/Dots Per Inch)
Larger - 150% = 144 DPI (Pixels/Dots Per Inch)
B) Go to step 7.
6. To Set a Custom DPI Size
A) In the left pane, click/tap on the Set custom text size (DPI) link (Windows 7) or Custom sizing options link (Windows 8). (See screenshot below step 4)
B) To the right of Scale to this percentage of normal size, click on the drop down arrow and select a percentage you want the DPI size to be. (See screenshot below step 6D) NOTE:You can also click and hold on the Inch Scale below this and drag it to change the percentage.
C) If needed, check the Use Windows XP style DPI scaling box to make text and items clearer in programs that are not designed for higher settings than 96 DPI (100%). (See screenshot below step 6D) NOTE:See the TIP box at the top of the tutorial.
D) Click/tap on OK. (See screenshot below)
8. Click/tap on the Apply button. (See screenshot below step 4)
9. Click/tap on the Log off now button to apply the DPI changes. (See screenshot below) WARNING:This will log you off immediately. Be sure to save anything you are working on before you click on this.

To Restore Default 96 DPI Using a REG File Download

1. Click/tap on the download button below to download the file below.
2.Save the .reg file to your desktop.
3. Double click/tap on the downloaded .reg file to merge it.
4. Click/tap on Run, Yes (UAC), Yes, and OK when prompted.

Since doing my i7 build a few days ago I have had problems with some applications not displaying the content within their windows correctly. I have uploaded a picture of one of the interface that is doing it. It worked perfectly fine on all other windows 7 64bit installations I have had until I built the i7 one.
The problem is that whenever you initially load this interface up, it presents it self fine and well proportioned to the window it is held in. As soon as you try to move the window or close and then re-open it shrinks from the right side inwards and cuts off tabs at the top rendering them inaccessible.
I have tried formatting 3 times again and decided it must be something to do with the DPI scaling. I have tried your registry method and checked DXDiag, which is now displayin 96DPI for user and system (it was showing as User: 96 DPI and system 120 DPI as I read this thread). Still no luck!
Ive been trying to fix this for days now. I installed Vista 64bit on my other partition and there are no problems on with that version!
It may be a issue with the program itself running in Windows 7, or a setting in the program for it. You might check to see if there is a new update or patch available for it that may cover this issue. If not, then you might see if using compatibility mode with the program may help.

My son has messed with the desktop settings and the best I can assume from what he told me and what is on the screen is that he has changed the DPI to some ridiculously large size. Consequently I can only see a very small part of any window and I cannot use the GUI to alter this particular setting.
Is there a way, such as through safe mode with command prompt to restore a more reasonable 96 DPI? I have tried system restore, but it did not change the DPI setting.
