Hi, I now got probably the same issue with him (Moderator: split away from an old thread in CentOS 6 Support viewtopic.php?f=14&t=66829 - please don't hijack threads for unrelated problems). I just installed Centos7 on my computer. When I tried to change the resolution, I only got one available option of 1024*768. However, the recommended resolution may be 1920*1080. I tried to solve this as follows.
[root@localhost X11]# cvt 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
[root@localhost X11]# xrandr --addmode default "1920*1080_60.00"
xrandr: Failed to get size of gamma for output default
xrandr: cannot find mode "1920*1080_60.00"
I got a failure the I type in 2nd command. I also have one monitor installed.
[root@localhost X11]# lspci | grep -i --color 'vga\|3d\|2d'
00:02.0 VGA compatible controller: Intel Corporation Device 3e92
Can you please give me some advice on that? that will be greatly appreciated. Thanks.
Unable to get good resolution on monitor

Please post the output from lspci -nn | grep -i vga
Is the xorg-x11-drv-intel package installed? Post the contents of /var/log/Xorg.0.log either here on on http://pastebin.centos.org and link to it.

The future appears to be RHEL or Debian. I think I'm going Debian.
