Changement résolution durant boot (driver NVidia)

Bonjour,

J'utilise les drivers propriétaires NVidia (pour une GeForce 750 TI) sous Ubuntu 16.04. (Je fais un peu de 3D avec Blender, les drivers proprio sont obligatoires).
Ma carte est branché en HDMI sur une TV Sony Bravia qui date un peu et n'a aucune option pour régler les problèmes d'overscan...

En bidouillant un peu dans nvidia-config, j'ai fini par trouver les paramètres "de mes rêves" : 1920x1080_60i +0+0 {viewportin=1920x1080, viewportout=1820x1024+50+28}
Ils me permettent de voir tout (pas de panning).

Mon problème est le suivant : ce mode d'affichage ne semble "tenir" à l'écran que quelques secondes lors de l'affichage de la fenêtre de login... Le Xorg.0.log ci-dessous sera plus parlant :

La ligne à 61.413 correspond à mon action d'aller dans nvidia-settings pour ressaisir les paramètres et faire "Apply". Mais on voit qu'à 11.043, ce même mode avait été choisi, puis il est remplacé (plusieurs fois) par "je ne sais quoi"...
Auriez-vous une idée de l'origine du souci ? (Qui demande à changer le mode plusieurs fois comme ça durant le boot ??)

En espérant avoir été complet... Merci d'avance
