Bonjour,
Hello,

Depuis quelques semaines, je lance mes jeux GOG mais ne peux y jouer qu'en mode fenêtré.
Sauriez-vous comment puis-je régler le souci ?
Je pense que c'est dû à une mise à jour de Windows 10 car j'ai eu le même problème avec STEAM.
Mais depuis, il y a eu une mise à jour STEAM et tout fonctionne normalement.
Pour GOG je ne peux pas jouer à mes jeux en fenêtre aussi réduite...

Since a few weeks, I launch my GOG games and I can only play in small windows (I'd love to play full screen).
Do you know how to fix this issue please ?
The issue may be the last windows 10 update (since 3rd or 4th week of may 2019).
I had this issue on STEAM too but the last STEAM update must have fixed it.

Merci et bonne journée.
Thanks, have a nice day.

Je ne peux jouer à aucun jeu donc je n'achèterai plus rien sur GOG tant que ça ne sera pas résolu.

And that's your good right, of course.

However, if you write something like: ...it gives the impression, that the fault lies on your side. Not on GOGs.

Edit: to be more clear...I also have the newest Win10 update - yet I have no problems like you describe.

Thanks for your answer. I think it's windows 10... But a steam update fixed the issue. Do you know if GOG will fix it soon please ? Have a nice day

Sorry but it's not possible to play in a so small window......

I just edited my comment, when you wrote yours, so you may miss it.

Therefore here again: I also have the newest Win 10 update installed - but I have no problems like you describe.

You sure, you didn't change anything else on your system?

I don't think so but thank you for your help BreOl72 :))

Alt+Enter

Hey thanks for your advice. I already tried Alt + Enter but it doesn't work.
But when I connect my computer to my TV (HDMI), I can play with full screen... Very strange.
Now I have to find how I can play without my TV lol.

Hmm all of this looks like the problem is with your GPU (either a botched configuration or a corrupted/incorrect driver) or some particular Windows graphical config.

Do you have any problem with any other program? Any window at all?

Also, do you use Gog Galaxy? Have you tried opening the game without Galaxy running?
