- Added to my Que on 4-14-2026 When projector is being used in touch screen mode: the screen that is being manipulated is the desktop and not the projector — removed from que 4-16-2026 [2026-04-16 13:37] Teacher uses his monitors in both duplicate and extend modes depending on his lesson and activities. The interactive board requires extended screens. Furthermore, when the settings are changed in that way, the tablet PC settings get defaulted, requiring the user to identify which screen is touch, and which is not. So I repaired these settings and tested. Touch is now working and calibrated. But the pc is lagging when taking touch input. For example: minimize/ maximize, volume bars, start stop or any touch command lags, and then will try to execute those actions 2-3 seconds after input. So it appears like it’s not working but it actually is. - this lag is most likely due to cpu load issues, or maybe drivers for the touch reader device.
