+# Set display name to work with. You can get it via 'xrandr --listactivemonitors'
+display="HDMI-2"
+# Set width of this display in px
+width=1600
+# Set height of this display in px
+height=900
+
+# Sometimes cvt and gtf generates different modelines.
+# You can play around and look which of them gives best result:
+modeline=$(cvt ${width} ${height} | grep "Modeline")
+# modeline=$(gtf ${width} ${height} 60 | grep "Modeline")
+
+# Some important data needed to xrandr:
+modename="${width}x${height}_my"
+params=$(echo "$modeline" | sed "s|^\s*Modeline\s*\"[0-9x_.]*\"\s*||")
+
+echo "Set resolution ${width}x${height} on display $display:"
+echo "$modename $params"
+
+# Simple logic:
+# 1. Switch display to safe mode which always exists (I believe) to avoid errors
+xrandr --output $display --mode 640x480
+# 2. If display aready have our mode -- we must delete it to avoid errors
+if $(xrandr | grep -q "$modename"); then
+    # 2.1. Detach mode from display
+    xrandr --delmode $display $modename
+    # 2.2. Remove mode itself
+    xrandr --rmmode $modename
+fi
+# 3. Create new mode with freshly generated parameters
+xrandr --newmode $modename $params
+# 4. Attach mode to our display
+xrandr --addmode $display $modename
+# 5. Switch display to this mode immidiately
+xrandr --output $display --mode $modename
