Kalleh24680 ConseraOfficial One of the patches changed fullscreen to a borderless windowed mode. I don't remember why they did it, I wasn't having any problems with my game's resolution. But anyway, have you tried the shortcut to make it toggle between regular windowed and borderless windowed? Alt+Enter. You can also force it into bordered windowed mode by (in the library view) clicking on the ... on Sims 2 and selecting view properties, then adding a -w to the advanced options field. Some players reported that after trying one of those, they were able to set resolution again.
I don't think they explicitly explain why they added borderless window mode in one of the patch note. But it makes sense why they added it. It's a modern display feature and makes some people lives more convenient. I'm loving it since I got a dual monitor setup and it makes multitasking convenient and I don't have to wait for my computer to unfreeze everytime I tab out
I also have a dual monitor setup, so I keep Sims 4 in windowed mode too.
Why in window mode if you have dual monitors? Your game looks better in fullscreen/borderless window mode
One monitor is hooked up to a Windows machine for Sims 2 and the other is hooked up to my Mac laptop and I use Synergy to go between the two monitors/computers with my mouse and keyboard. I can go between them with the games in fullscreen just fine, and Legacy is in fullscreen/borderless windowed right now. So I can play Sims 4 and look at things on the Windows screen or I can play Sims 2 and look at things on the Mac screen. But I can't drag items from one screen to another or open things from one on the other because they are completely different operating systems. It's not a "traditional" dual setup. When I needed to look at screenshots from Sims 4 yesterday side by side with my game for my build, I had to move the game window over because it's not possible to drag them to the other screen. I also do everything else on my Mac, so it's easier to leave it in windowed mode so I can easily pop in and out of the game. Some of it I could do on the Windows screen, sure, but I hate Windows. If Sims 2 was playable on my Mac, I would have a traditional dual screen setup and wouldn't have a Windows machine.
