Avocor G Series vs LG CreateBoard: Is the Difference in Writing Experience Worth the Cost?

For people who write on the board all day, often yes. For a classroom or meeting room where the board mostly shows slides, usually not. The Avocor G Series is built around writing feel: FlatFrog InGlass touch, palm rejection, fine-tip passive styluses and optically bonded glass that Avocor describes as zero parallax. The LG CreateBoard TR3DQ is built around value and software: Android 14 with Google EDLA, 50 touch points, two pens and LG's teaching tools. SourceIT does not sell the G Series. If you want a premium writing surface that we do stock, the closest is the bonded-glass Avocor H Series AVH-6520 at S$4,971.25, against S$2,587.50 for the LG 65TR3DQ (both listed 31 Oct 2026). That puts the cost of better writing at about S$2,400 on a 65-inch board.

What actually makes writing feel different?

Three things decide whether ink appears to come out of the pen tip.

• Parallax. This is the gap between the surface you touch and the pixels underneath. With an air gap, ink appears slightly offset from the pen, and the offset gets worse when you view the board at an angle. Optical bonding fills that gap. Avocor makes bonding claims for both the G and H Series. We found no equivalent claim on the LG pages we used.
• How touch is sensed. FlatFrog's white paper describes InGlass as light carried inside the glass itself. By contrast, infrared touch relies on a grid of light just above the surface, which needs a raised bezel and can register things that are not touches. The paper dates from 2015, so treat it as background on the technology rather than a spec for the current G Series.
• Palm and pen handling. A board that ignores a resting palm and tells pen, finger and palm apart lets people write naturally. The G Series lists palm rejection and a palm rest.

Touch points measure how many people can use the board at once. Parallax and palm rejection decide whether one person enjoys writing on it.

Where does LG make up ground?

The TR3DQ wins on features that matter in schools. It runs Android 14 with Google EDLA, so Google Play, Drive and Classroom apps run on the board itself. Its 50 touch points let several students work at once. LG's CreateBoard Share mirrors from student devices through a web page and a code, without installing an app. LG CreateBoard Suite and ConnectedCare handle device management, though ConnectedCare is sold separately. LG rates the TR3DQ for 16 hours a day, 7 days a week.

The G Series has no built-in OS listed, only an OPS slot. A school would need a Windows or Android module before it is useful on its own. Its 20 touch points are also fewer than the TR3DQ's 50. In a classroom where group work at the board matters, that is a real limitation. For more on LG's range, see LG CreateBoard Review.

Who should pay for the better writing surface?

• Worth it: design reviews, engineering mark-ups, maths and science teaching that is mostly handwritten, and rooms where people regularly stand to the side of the board.
• Probably not worth it: rooms used mainly for slides, video calls and occasional notes, and large classroom rollouts where the budget is better spent on more boards or on training.
• Middle ground: the Avocor H Series, which SourceIT stocks, adds bonded glass and PCAP touch. It costs less than buying a G Series elsewhere, and it is compatible with the Lenovo ThinkSmart Core for meeting rooms.

How can you judge writing feel before buying?

1. Write small text, about 1 cm high, and check that the ink lands exactly under the pen tip.
2. Repeat from one side of the board at an angle, as a teacher would.
3. Rest your palm on the glass while writing and watch for stray marks.
4. Draw quick strokes and circles to see whether the ink keeps up.
5. Have two or three people write at once, using pens and fingers.

Ask for a demonstration unit or a supplier visit before committing to a large order.
