This article explains how to fix touch is rotated 90-degrees after the monitor is rebooted or powered on while in portrait mode

See the below information concerning touch being rotated 90-degrees after monitor is rebooted or powered on while in portrait mode.

Affected monitors:
PCAP monitors with NAPA CTR-9300 controller, in this case the 2494L
Problem seen on POSReady 7 system

Symptom:
After a system in portrait mode is rebooted or powered-on, computer remembers the video rotation setting but appears to ‘forget’ the touch rotation setting, resulting in touch response that’s rotated 90 degrees.

For example, a touch in the physical upper left (which would be the lower left in landscape mode) results in touch response in the portrait-mode OS in the lower left.

WORKAROUNDS:
1. We identified the basic/simple workaround: reset the touch USB device after PC power-on. This can be done either by physical plug/replug of the cable, power cycle of the ET2494L touch monitor, disable/enable the touch device from the Device Manager, or USB reset system command from the PC. Simplest way to ‘silently’ implement would be a batch file in the Windows startup process to reset the touch USB device.

2. A custom Elo driver can be created that sends a custom touch reset command when NAPA controller detected
