Tente usar as configurações nvidia - > Configuração de exibição do servidor X - > Detectar exibições. Eu usei com sucesso para exibir a área de trabalho em dois monitores (um @ 2550x1440, o outro @ 1920x1080).
Eu tenho um laptop e estou tentando conectar dois monitores, um dos quais deve ser executado em 2560x1440
Eu instalei os drivers nvidia-331-updates proprietários e (eu acho) configurados para usá-los por padrão ( prime-select nvidia )
Eu tenho um Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz e um Nvidia 710m runnung Ubuntu 14.10
Quando tento definir a resolução via:
~$ cvt 2560 1440
~$ xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
~$ xrandr --addmode HDMI1 "2560x1440_60.00"
~$ xrandr --output HDMI1 --mode 2560x1440_60.00
Eu recebo o erro: xrandr: Configure crtc 2 failed

ATUALIZAÇÃO:
Seguindo as instruções aqui: link Eu era capaz de obtê-lo para a saída sem o erro, no entanto, agora meu monitor tem um erro "fora do intervalo"
Tente usar as configurações nvidia - > Configuração de exibição do servidor X - > Detectar exibições. Eu usei com sucesso para exibir a área de trabalho em dois monitores (um @ 2550x1440, o outro @ 1920x1080).
Sinto muito, mas você está sem sorte. A exibição de 2560x1440 pixels requer o uso de uma freqüência de chip gráfico mais alta e, mesmo que esteja dentro da especificação do chip, os fabricantes de laptops desativam qualquer coisa acima de 1920x1080 para evitar o superaquecimento.
Ainda estou para ver um laptop cuja especificação diz Support of external monitor @2560x1440 pixels .
Você pode usar seu monitor brilhante com uma estação de trabalho de mesa com placa discreta com saída HDMI - desde que essa resolução esteja dentro da especificação da placa.
