See the quality

My platform is Windows 10

Please sent me a complete video on how to fix this

OK, so it's exactly #40: your device definition is waaaayyyy bigger than your computer screen definition (the rendering is done on your device, then captured/resized to a tiny grid, so it's ugly). Btw, if you resize to "pixel-perfect" (Alt+g), the rendering should be perfect (but it's too big).

The real solution is to use a computer screen with a better definition :trollface:

To mitigate the issue, mipmapping has been implemented, but only for OpenGL, so you could try:

scrcpy --render-driver=opengl

However, on Windows, OpenGL drivers are not always ok, so it may be better (in quality) but worse (in performance or stability).

probably this has to do with windows hidpi settings. On .exe property go to compatibility-> settings for hidpi -> set to application.

@rom1v your app comes with hidpi support built in. Unexperienced windows users may not know how to handle this sort of bad scaling so you should advise what I told on readme/faq

rom1v commented 4 years ago

@sagarcyber-hw4 As @Manu99it suggested, try to change the "scaling behavior": https://github.com/Genymobile/scrcpy/blob/master/FAQ.md#the-quality-is-low

@Manu99it However, given the screenshot, it really looks like linear downscaling issue (#40).

Manu99it commented 4 years ago

@rom1v didn't see that you already added that to FAQ, excuse me 😅. However actually the linear downscaling issue could be also because when windows is used on hidpi screens, size of things (like apps, buttons etc.) is set 150/200% or even more. Then, windows scale down apps to have 100% size but that won't be pixel perfect anymore. To me this is always been a windows bad behavior to manage hidpi. Having hidpi "application" managed as default is not the best thing because many apps doesn't have hidpi support. "System" managed most likely breaks apps that support hidpi and "advanced system" sometimes does a good work sometimes not. So one have to always manage that behavior per each app :/

Also I'm unsure it's like #40, screenshot quality isn't that great so who knows, we will know when op reads :D

Outstanding!!!! Been using scrcpy for 2 years, was convinced it was #40 , I was just stuck with it. Nope. Caught @Manu99it's suggestion, regarding the scaling. the hidpi issue...done.

Feels like I'm on scrcpy 2.oh! It's beautiful. Thanks!
