Black bar on monitor

[axility]

so i bought a monitor samsung s22a100n "21.5" and its native resolution is 1920*1080
and when i plugged it in the gpu i got a thin black bar almost 3 mm vertically on the edg of the screen
now the monitor dosent have any auto adjust and the driver is updated my gpu driver is also updated
i tried to move the desktop from nvidia panel it went behind the black bar which got me wondering maybe the screen is not ok , i was wrong i changed the resolution it worked fine no black bar
i turned off my gpu it also work fine
now i am left with 2 options either this monitor is weird and in native will always show that bar or the graphics card is damaged

now i just want to know anyone faced this or idk im confused

system
win 7
cpu e7500 core 2 duo
gpu gt430 gigabyte oc edition
ram 8go
mobo GA-G41MT-ES2L gigabyte

( ik my pc is old but i cant afford to buy a new one no furthur explanation )
thank you

If it was the video card the issue would have shown up on the old monitor also. It's likely a combination of the card and the monitor model. See if using another connection type makes this go away.
