Caixas de texto aparecem à direita da tela como "fantasmas"
Isso pode ser causado por um cabo de monitor defeituoso. No seu caso, por não ter o cabo conectado corretamente, a blindagem foi comprometida.
On what has always been a perfectly good LCD monitor, you begin to see a faint but distracting “ghost image” to the left or right of desktop elements (like windows, icons, or black text on a white screen). Unlike the burned-in images associated with old CRT or new plasma monitors, this image is “live” — when you move screen elements or change the contents of the screen, the ghost image moves and changes, too. The effect looks a bit like those slightly-offset ghost images you used to see on television screens back when t.v.’s were hooked up to “rabbit ears.”
In most cases, it’s the monitor cable. If this just started, you probably added some new electronic gizmo to your desktop, or the shielding on your current monitor cable has been compromised in some way. If the monitor cable is touching another cable, a modem, or even an inkjet printer, move the cable. If this doesn’t fix the problem, replace the monitor cable.
