Avocor G Series Review: Why Would Anyone Pay More for an Interactive Display?

Mainly for the writing experience. The Avocor G Series uses FlatFrog's InGlass touch technology behind zero-parallax, optically bonded glass, which Avocor says gives "pixel-perfect inking": the line appears directly under the pen tip instead of slightly offset, as it can on screens with an air gap or an infrared frame above the glass. It also supports palm rest and palm rejection and up to four fine-tip passive styluses. For teams that sketch, mark up drawings or write at length, that can justify the premium; for rooms that mostly show slides, it rarely will. We have not tested this unit ourselves. This review is based on Avocor's G Series datasheet (August 2025) and FlatFrog's published technical material. SourceIT does not currently list the G Series; the Avocor models we do list start from S$2,236.52 for the 65-inch S Series (listed 31 Oct 2026).

What does the G Series offer?

From Avocor's G Series datasheet, August 2025. Note the 85-inch model code is AVG-8560.

What is InGlass, and how is it different?

Most interactive displays in schools and offices use infrared (IR) touch. A frame around the screen projects a grid of infrared light just above the glass, and a touch is detected where a finger or pen breaks the beams. FlatFrog's 2015 white paper describes the drawbacks: IR "depends on an above-the-surface light matrix", "requires a protruding bezel" and can register touches that are not real, such as a sleeve near the surface.

InGlass works inside the glass. FlatFrog describes it as based on frustrated total internal reflection: light is "injected into the core glass", and a touch disturbs that light where it meets the surface. Because detection happens at the surface rather than above it, the glass can be flat to the edge and bonded directly to the panel. FlatFrog's 2021 description adds that InGlass can tell pen, finger and palm apart.

Two cautions. The white paper is a 2015 technology document claiming more than 1,000 pressure levels and up to 80 touches; Avocor's shipping G Series datasheet lists 20 touch points and no pressure specification, so go by the datasheet. And we found no published InGlass latency figure, so any claim that it is "faster" than a particular IR board cannot be checked.

Premium touch is about where the ink lands, not how many fingers the screen can count.

What does zero parallax mean in practice?

Parallax is the gap between where the pen touches the glass and where the line appears on the panel underneath. It is caused by distance: cover glass, an air gap, then the LCD. Viewed straight on, the offset is small; viewed from the side, as a presenter standing beside the board usually does, it grows. Optical bonding fills the air gap so the image sits closer to the surface. That is why bonded glass matters most for people who write a lot: detailed diagrams, handwriting, maths and engineering markup.

Why would anyone pay more?

• Writing that feels like a whiteboard. Fine-tip styluses, palm rest and minimal parallax suit long writing sessions.
• Several writers at once. Up to four passive styluses for workshops and design reviews.
• Brightness. 500 nit is brighter than the 350 to 450 nit listed for the Samsung, LG and MAXHUB boards covered in this series, which helps in bright rooms.
• Flexible compute. An OPS slot lets you add a Windows PC for meeting and creative software.

The G Series does not, on its datasheet, include a camera or microphones. Video meetings need a separate camera or video bar.

What can you buy from Avocor in Singapore instead?

SourceIT lists three Avocor touch ranges that show the same trade-off at different prices. According to Avocor's datasheets, the H Series uses projected capacitive (PCAP) touch with up to 40 touch points and one stylus behind 2 mm optically bonded glass, at 400 nit with an OPS slot. The E50 Series uses IR touch with up to 40 points and one stylus, runs Android 13 with Google EDLA, and is rated for 16/7 use. The S Series is Avocor's Google EDLA education range. At SourceIT, a 65-inch E50 is listed at S$3,728.05 and a 65-inch H Series at S$4,971.25 (listed 31 Oct 2026). On the datasheets, the main differences are PCAP touch and bonded glass on the H Series. We compare brands in Avocor vs Samsung Flip Pro, Avocor vs MAXHUB and Avocor G Series vs LG CreateBoard.

Frequently asked questions

What is Avocor InGlass? A touch technology from FlatFrog that detects touch inside the glass using frustrated total internal reflection, rather than with an infrared frame above the surface. Avocor uses it as InGlass M5 Intelligent Touch on the G Series.

What does zero parallax mean on an interactive display? The ink appears directly under the pen tip, with minimal offset. Optically bonded glass reduces the gap between the writing surface and the panel.

How many pens does the Avocor G Series support? Avocor's datasheet lists up to four fine-tip passive styluses, with two 3 mm styluses included, and up to 20 touch points.

Does the Avocor G Series have a camera? No camera or microphones are listed on Avocor's G Series datasheet. Video meetings need a separate camera or video bar.

Can I buy the Avocor G Series in Singapore? SourceIT does not currently list the G Series, so ask us about availability. We list the Avocor H, E50 and S Series, from S$2,236.52 on 31 Oct 2026.
