GT-CTS18.5

It's the sweet spot for seated-one-user interaction. At 18.5" the comfortable touch reach covers the whole screen without leaning, so it fits reception desks, check-in counters and compact info terminals. Go 21.5"+ only if multiple users step up or you need bigger UI targets.

Yes. Windows auto-matches the HID touch rectangle to the display EDID on first plug-in. On 18.5" the pixel density is low enough that tap targets stay large; if your UI was designed for a 24" layout, just bump font/button sizes ~10% and it feels native. No firmware work.

Easily. 10 ms is one touch report frame; for tap-confirm-scan retail flows the bottleneck is usually the app, not the panel. Where 18.5" helps is fewer mis-taps: bigger targets + stable HID means less double-tapping and less "did it register" hesitation during peak hours.

Generally yes for 3 mm clear acrylic, but it depends on the dielectric. Acrylic is fine; polycarbonate with anti-scratch coating can vary. We tune the controller gain for the cover-glass-to-sensor gap, so tell us the exact front-window material and thickness and we baseline it before shipping — don't guess on-site.

The sensor doesn't care about ambient light, only temperature. 18.5" controller is happy up to ~60°C; if direct sun pushes the sealed enclosure higher, add a small vent or thermal pad to the controller bracket. The glass itself won't drift — PCAP baseline auto-recovers as it cools.

No. Calibration lives in the controller, not the OS. Swap the host PC, change the language image, even move the panel to another kiosk — the touch stays aligned. Only if you change the physical glass stack or bezel do you need a re-baseline.

Standard black-matrix border is 4–5 mm, which hides the channel routing cleanly. If your ID wants a tighter 3 mm visual frame, we can shrink the BM print, but keep a 1.5 mm mechanical overlap under the bezel so the gasket seals. Edge touch gets a final tune on your real front-panel sample.
