Problem with screen size on TV connected via HDMI in Windows 10 [SOLVED]

Not only did Micro$h4ft mess up the DPI scaling as now you cannot have one scaling level across all connected displays which in turn makes text looks blurry in some places like services.msc and GPEDIT so I am not doing any DPI scaling anymore and living with a 100% scaling......

but now I have a problem, my SONY TV has a 1920x1080 resolution while my monitor has a 2560x1440 resolution so when I connect the HDMI display my monitor switched back to a 1920x1080 resolution as the default option is to duplicate the display on both screens.

So what I'd do then is set it to Extend These displays that way I can have a 1440p resolution on my monitor whilst keeping the TV on the right hand portion of the screen @ 1080p

This worked great in Windows 7 but in Windows 10 the screen on the monitor only appears in a small portion of the screen (say about 25%) and the rest is black borders as if it was not using the full size.

I tried everything I can but couldn't figure a way to make it full size so for the sake of watching the movie I just set the HDMI to Duplicate These Displays that way everything is full size but my monitor runs @ a 1080p non-native resolution and thus everything is blurry on it.

Can someone suggest any idea to help me fix this?

Found the solution accidentally!!

It seems the image was appearing as a much smaller size on the TV with black borders all around because for some weird and stupid reason, when I connected the HDMI cable to the TV it kept my DPI scaling on the monitor at 100% as it was before, but I don't know who the heck told Windows 10 to set the DPI scaling to 150% which shouldn't really decrease the total area of the screen but that's what was happening.

So I move the DPI scaling on screen two (which is the TV) back to 100% scaling and now the image on my TV appears as a full sized image covering the entire area :)

I was just about getting fed up and going back to Windows 8.1 Pro this time but luckily I found the trick before I waste another day of hard work formatting.

Micro$h4ft

What are we still in high school? Grow up :rolleyes:

Glad you found the solution though. That is a bit weird. Usually that kind of thing is caused by overscan or underscan on HDMI that is corrected in the video driver control panel someplace.

sorry for that

do you think it may be nVIDIA's Drivers fault or is it Windows' fault?

Because in Win 7 or 8 that never happens, if you extend the desktops, by default the scaling is @ 100% for both displays as I never tinkered with it and even though the resolution on my monitor and TV screen are not the same, the sizes are all perfect since I didn't do Duplicate These Displayus but rather, Extend These displays so each screen should have its own 100% resolution, but in Win 10, it was showing me only like a quarter of the total size and the rest were black. it was like a small preview window I would've never thought that has anything to do with DPI scaling as everything still looked sharp on the TV just small... instead of big since Windows performed a 150% DPI scaling so naturally things should be bigger

I have complained in the past before about the whole underscan/overscan retardedness with HDMI and how it feels like regression from DVI which is perfect every time. And it isn't always consistent either. So, maybe not so much an nvidia issue, partially a MS issue (like you said DPI adjusting that shouldn't make that act up), and partially a HDMI issue since HDMI introduced that whole scaling issue in the first place.

makes sense!

Glad I found the solution! took a lot of tinkering with all the settings

I'd be curious, if you turned the DPI back up does the NV control panel show it set to underscan?
