I am trying to maximize my resolution where I have Resolution: 800x600 (4:3) and Refresh rate: 61Hz

I tried the following, but it did not work:

$ xvinfo
X-Video Extension version 2.2
screen #0
 no adaptors present


$ 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

$ xrandr --newmode clever_name 173.00  1920 2048 2248 2576  1080 1083 1088 1120
$ xrandr -q
Screen 0: minimum 640 x 480, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
   800x600        61.0* 
   640x480        60.0  
  clever_name (0x11d)  173.0MHz
        h: width  1920 start 2048 end 2248 total 2576 skew    0 clock   67.2KHz
        v: height 1080 start 1083 end 1088 total 1120           clock   60.0Hz


$ xrandr --addmode default clever_name
$ xrandr --output default --mode clever_name
xrandr: Configure crtc 0 failed
