I have windows 10 64 bit with intel HD 3000 graphics and nvidia gt740m on a laptop.
Until yesterday i was playing in 4:3 aspect ratio in a game (counter strike) and everything was fine (stretched). Today when i logged in the game it had black bars. Nothing changed since yesterday, i just logged off at night and logged back in today.
Here is my update history. http://prntscr.com/eg0di0
I am searching on the issue for multiple hours and still haven't found a fix. My nvidia control panel doesn't have a display tab so i can change scaling option from the intel control panel. Also because my intel hd is 3000 thats the control panel i get with the latest driver i can install. http://prntscr.com/eg0j34 Do you see were it says scaling? There i have maintain display scaling or scale fullscreen on all resolutions. This prevents the black bars from appearing on desktop. But when i launch csgo they appear. If i keep the intel control panel on the laptop screen (i am using a monitor for my main display) when i launch csgo the option in the scaling field changes to "Maintain Aspect Ratio". If i try to change it back, when i click on the control panel or alt tab to it, it changes back to the options i had selected before.
If i play the game on Windowed Fullscreen, then csgo doesn't magically override my display settings and i can play on 4:3 stretched, but the input lag is too big.
I have tried reinstalling drivers, updating them, messing around with different resolutions even changing some registry values (https://www.reddit.com/r/GlobalOffensive/comments/4hneko/black_bars_issues_on_windows_10/d2r21ki/) but nothing works. And yesterday everything was just fine! I installed HRC also and tried it but when i press the hotkey to change to the lower resolution the same problem (black bars) appear on my desktop also. Which means by default it changes to maintain aspect ration in the intel control panel. I can see some correlation there but i can't figure out a way to find it.
Only workaround is to hit Ctrl+Alt+f11 which the hotkey for panel fitting http://prntscr.com/eg2lco 2 times and then it stretches. Meaning, on the intel control panel on my laptop screen the scaling field (which magically changed to "maintain aspect ratio" when i launched to game) changes back to maintain display scaling. Problem with this is it changes the whole screen resolution so i have to change it back when i quit the game.
Any ideas? Do you know were i can find something similar to override application settings as show here? http://prntscr.com/eg0p0q (i cant get the above control panel to show). Do you think its a driver issue? I have the latest. Or maybe intel/microsoft/valve changed something internally in 1 night? If so can something be done or its an old model and intel just dont care anymore?
