I want to know if there is a way to disable auto scaling on start screen in windows 8.1. My laptop does not have a touch screen, so this scaling is useless for me and it get worse when I connect my laptop into my TV, the Tiles on my screen get even bigger that it already are.

Normally on my laptop I can use the option show more tiles, this options enables 6 rows of tiles, but I don't know why on my TV this option doesn't have any effect and the start screen and it shows only 4 rows of tiles.

My TV is a Sony 42" Full HD and my laptop a Sony Vaio SVS 15.

This is on the Laptop:

and this on the TV:

Hi,

We can try to configure this setting: under Control Panel\Appearance and Personalization\Display

Please check on "Let me choose one scaling level for all my displays" option.

This setting determines whether the automatic DPI-scaling of Windows 8.1 is enabled or not. If the setting is unchecked, Windows will automatically select scaling values for each display the PC is connected to.

For detailed information about what is changed on Windows 8.1 DPI Scaling, you can refer to this article:
