Why is Windows 7 treating my TV as the primary display?

I can't figure out why my TV is "1" in properties. I can make my LCD the default but whenever I set the option to "duplicate" the resolution on my pc matches my tv - meaning it's the wrong resolution. I know it should be possible to have two different resolutions when duplicating screens - I've done it before in Vista.

Also, if I use win-P to switch back to one display Windows will shut off my LCD and show the desktop only on my TV

Is there any way for me to force Windows to use my LCD as default? As you can tell in the window, it's already set to main display. It just doesn't do anything. #2 is my LCD. #1 is my Sony HDTV

repeatedly pressing win+p should change through a couple display settings, but since its saying your tv is monitor #1 its going to change between, expanded desktop, 2nd screen only, and clone screen.

you should be able to click on #2 and check off "this is my primary monitor"

i had a similar problem as well. i think its to do with the type of connection. my graphic card has a vga (which connects to the lcd tv) and a dvi which connects to the monitor. the computer by default tries to look for a screen on the vga port first and then the dvi and sets it as such.

my other card which has two dvi output and i use dvi to vga adapter to connect to the tv, doesnt have that problem since to the computer, its both dvi connectors on the graphic card.

My DVI-out to the TV also gets assigned to #1 as well. Knowing this problem from RC I installed Windows 7 final with the DVI cable unplugged from the PC. But that didn't fix it, Monitor became #1 but as soon as the cable was back in it would make the TV #1 :/

      But we are talking about Elon Musk, no AT&T... I know big companies are evil, but Elon and his companies are in another level which is much more dangerous.
    • New PowerToys update fixes memory leaks and other issues

      New PowerToys update fixes memory leaks and other issues by Taras Buria Another bug-fixing update is available for PowerToys version 0.100. After releasing version 0.100.1 with a bunch of bug fixes and patches, Microsoft pushed version 0.100.2 to address two important issues with one of Command Palette Dock's features. With PowerToys 0.100.2, Microsoft fixed the performance meter displaying incorrect values and memory leaks, which are particularly unwanted things in the current situation with overpriced PC hardware. Here is the changelog: Reverted a Performance Monitor dock refresh change that forced item refreshes on every metric update Fixed a memory leak in the Performance Monitor dock extension by reusing stable network upload/download band items instead of creating new list items on each refresh For those unfamiliar, Command Palette Dock is a relatively new addition to PowerToys. It is a taskbar-like tool that you can keep on top of the screen to pin various useful widgets, commands, and more. It can display time, weather, your PC's performance metrics, and more. Microsoft introduced the Command Palette Dock in March 2026 in PowerToys 0.98. Microsoft has dedicated documentation for Command Palette Dock, and you can check it out on the official Microsoft Learn website. You can update PowerToys to the latest version by going to Settings > General and clicking "Check for updates." Alternatively, you can download the installer from GitHub using this link. In other news, Microsoft is working on a new window-management utility for PowerToys. Called Alt Window Cycle, it will let you use the Alt + ` shortcut to switch between different windows in a single app. You can learn more about the tool here.

      You did take leaf out of Trumps book already and had brexit - only to harm yourself. The same goes with this AI nonsense. The obvious solution for these companies is to move their head office to Brussels. I can see quite much irony there... 🙂

      Wonder if they are trying to slow down Linux traction (not saying this is the only factor) in the consumer space. With the most pressure probably being steam deck/box, etc.
