How to change xrandr maximum value.

Screen 0: minimum 640 x 480, current 800 x 600, maximum 800 x 600

default connected 800x600+0+0 0mm x 0mm 800x600 60.0*

56.0 640x480 60.0 “1024x768_60.00″ (0x78) 63.5MHz

    h: width  1024 start 1072 end 1176 total 1328 skew    0 clock   47.8KHz

    v: height  768 start  771 end  775 total  798           clock   59.9Hz   

“1024×768″ (0x79) 70.0MHz

    h: width  1024 start 1072 end 1176 total 1328 skew    0 clock   52.7KHz

    v: height  768 start  771 end  775 total  798           clock   66.1Hz

where the minimum, maximum, and current value of xrandr will be store ?

If I connect my monitor directly with machine I'm getting 1024x768.

If I connect my monitor via KVM switch the maximum value is 800x600 how to change the max value?

It might be a hardware issue (perhaps, signal quality after KVN switch?).
