1280x1024 is the maximum for a 17 .. 19" monitor.


Remark : Why use the title HELP ? This is a HELP Forum.
Descriptive titles, please.

It doesn't matter what the graphics card can do, if the monitor can only support lower resolution. If you want higher, you need a better monitor. And as knudfl said, use a subject that describes your problem. You won't get much help with a subject of HELP!!!.

You are limited by both, what the video card can do and what the display device can do. You can grep the /var/log/Xorg.0.log for "mode" to see what X thinks about things. In addition to what xrandr might output when run with no parameters. Sometimes the EDID that the monitor uses is in error and some trickery can be done to circumvent things. Check for firmware upgrades, which might make all of this moot. And be aware that sometimes the connection method is the limiting factor for monitors with multiple input types.

Im sorry for putting the title as help because im new to this website about this is what the terminal shows everytime I try to change the resolution "John@JohnPC ~ $ cvt 1366 768 60
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz

Current serial number in output stream: 24" before installing the nvida 304 driver my resolution was at 1366x768 after installing the max resolution I can get was 1280x1024 as you see above i tried to change the resolution but it has been fruitless so far is there any way around this my graphic card is nvidia geforce 7050 and my current graphic card driver is the nvidia 304 my monitor is acerx193hq the optimum resolution for me is supposed to be 1366x768 but i cant achieve that now so the graphic looks kinda lame on the resolution im on now prior to installing the driver the resolution and graphics was awesome but it kept on freezing so linux said that i should download the new driver to oversome the problem after installing the problem mentioned above occured.

And monitor {Brand and type number}.

It would be nice to have the outputs for:

$ grep -i "mode" /var/log/Xorg.0.log

and

$ xrandr

You shouldn't have to --addmode, it should already be there(if the card supports it, and the display supports it). Although I'm finding out that nvidia cards are far less informative relative to my ati card (that failed). At least when it comes to the proprietary driver.

For example on this ancient laptop with an intel video chipset:

$ xrandr
Code:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 2048
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 286mm x 214mm
   1024x768       60.0*+
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 disconnected (normal left inverted right x axis y axis)
(current mode is marked by a * in the output of xrandr)

And this can change between modes:

$ xrandr --output LVDS1 --mode 800x600

And of course restore it by chosing the other mode

$ xrandr --output LVDS1 --mode 1024x768

Your parameters might be different depending on the output of xrandr. Like VGA-0 or HDMI-0 instead of LVDS1.

The GPU in theory supports up to 1920x1440

$ cvt -v -r 1366 768

What it comes out to on my hardware. GeForce 6150. Oddly I get the same error as you, but my 1600x900 display doesn't do 1366x768. And I'm not quite sure why it bumps it to 1368, aside from it being a multiple of 4. Same result and stuff on my sansui which is a 1366x768 monitor, but only does 640x480 by default with the nvidia driver. And able to do 1024x768 with the nouveau driver.

I guess the nvidia drivers, at least the 304 / legacy ones really do suck this bad. At least it mostly works on my 1600x900 display. To be fair, debian jessie / testing which might be too bleeding edge for the proprietary nvidia drivers. I suppose you could get an aftermarket card (probably not nvidia) to use your display at it's native resolution.
