Screen Resolution too small

[Pian0Play0r]

Hello!
I've got a problem. My screen resolution from Linux Mint is too small.
Does anyone had the same problem? My PC is an Acer Aspire 5734z-4836.

Are you using the 1024x768 resolution, or other setting? Your maximum resolution on the screen, according to a Cnet review is 1366x768.

[Pian0Play0r]

Yes, the current Resolution is 1024x768. And I meant 1366x768 pixels.

Open a terminal and see if you can enter the command xrandr. If this is an unknown command or filename, install the x11-xserver-utils package, which will install xrandr. Now that you have xrandr loaded, open the terminal and type xrandr again on a line by itself. The output will look something like:

Code: Select all

xrandr
Screen 0: minimum 64 x 64, current 1280 x 1024, maximum 32000 x 32000
VGA-0 connected 1280x1024+0+0 0mm x 0mm
   1280x1024      60.0*+
   1600x1200      60.0  
   1440x1050      60.0  
   1280x960       60.0  
   1024x768       60.0  
   800x600        60.0  
   640x480        60.0

See if your desired 1366x768 resolution is available. If it is, simply choose it from your menu display settings.

If 1366x768 is not available, enter the following in your terminal window:

Code: Select all

cvt 1366 768
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync

The second and third lines are the output from the cvt command.

Code: Select all

xrandr --newmode 1366x768 85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
xrandr --addmode VGA-0 1366x768
xrandr --output VGA-0 --mode 1366x768

When you are entering the 3 lines, the first line numbers, except for the mode name, are simply copied from the previous box's Modeline, VGA-0 is replaced by whatever is in that position of the output of the xrandr command on a line by itself, and the final line should kick you over into the higher resolution mode.

EXCEPTIONS: If you get a message about being unable to read gamma from your display, and the line for the display starts with "default connected" this doesn't work. I have reported the bug to launchpad.

Thanks! I'll try it.

Semi-Necro:

I was told this may resolve an issue I have in which I can't see anything on my HDTV. I posted separately, but this is directly implied as a possible solve. Does anyone concur?

[cwsnyder]

Addendum: If you get the message about 'unable to read gamma' from your display, if you can change to a different video driver, that may fix the problem. For example, on LM 14 Cinnamon 64-bit Live DVD on my system, I first go the 'unable to read gamma' message, but was able to install the nvidia-current driver on the Live machine, then I was able to re-size the display. This doesn't always work, as a VM I have installed under VirtualBox of Bodhi Linux seems to have the correct video driver for VirtualBox, but still can't read the gamma.

[cwsnyder]

In case someone is still following this thread, I have found a fix for the case where the gamma of the display is not being read properly. What you do is change the third xrandr line from xrandr --output VGA-0 --mode 1366x768 to xrandr --output VGA-0 --gamma 1:1:1 --mode 1366x768.

Hello , i am a complete linux noob, as in i havnt sleep because i had the great idea of trying out some linux .
I know this question has to have been answered but i am such a noob that even the slightest change in the answer of some1 else compared to mine loses me.
I have just installed the newest Linux mint OS 64 bit,
i installed correctly (following this youtube guide: http://www.youtube.com/watch?v=AkKkuzWlaGo) the Nvidia propriatary Driver.
but i am still restricted to a low resolution and not the 1920x1080 that my screen and card can handle,
do i need to provide more information?\
can some1 help?
thank you in advance and again sorry for bad english and M$ office user

@pampidou,
What is the output of the terminal command xrandr on a line by itself? Your actual display is probably NOT VGA-0, that is just what I used as an example.

The error messages indicate that either a) the resolution which you wish to apply is already set up and available, probably under Menu >> Preferences >> Monitors, or b) the proprietary driver you installed does not work properly with your monitor/card combination, or c) you simply are specifying a monitor selection which does not match your installation.
