Laptop + monitor - niska rozdzielczość VGA + HDMI

Recommended Posts

Monitor zewnętrzny: LG 24MP48HQ

Po podłączeniu HDMI jest wszystko ok.

Natomiast po podłączeniu VGA rozdzielczość na dodatkowym ekranie jest bardzo niska.

1. Wbudowany ekran

Karty graficzne w laptopie:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GTX 660M] (rev a1)

Dodam, że muszę mieć podłączenie przez VGA, ponieważ przez HDMI jest podpięty drugi komputer.
