XP Displaying bug

[DELTA-km]

The displaying on the screen is inverted (right-left), the device has windows XP. It needs mirror to read right

Seems like at some point the rotation feature was enabled under your video card's options.

Right click on desktop->properties, from then on you have to enter either to "Nvidia control Panel", "AMD CCC Catalyst" or "Intel integrated Graphics" depending on which video card you have, then look around for monitor or screen options until finding anything related to Rotation, there should be different options with degree options (0º, 90º,180º) or simply "rotate to left/right/up/down", keep choosing each of them until you get your monitor back to normal.

Sorry, but the problem isn't about screen rotation, but it is display inverting (flip horizontal),I put a mirror so I can see the screen correct .

My bad, I shouldn't have said "Rotation", however that mirroring effect is also a feature, you'll have to look around until finding which option is causing it.

See if you have a restore point available and go to a time before this started. The only option I know that does this is for projectors so you can display with the projector being behind the screen not in front, maybe someone was playing around with those settings. You can also try to remove the video card from Device Manager, and reboot, that should reset the options for it to defaults.
