Display For Asus ExpertCenter P400 AiO P440VA P440VAEST 23.8 inch FHD LCD Touch Panel
iProGadgets OEM Repair Parts for the Asus ExpertCenter P400 AiO 24 (P440VA / P440VAES / P440VAEST) — Screen Reference and Fitment Check
Quick answer: this is a brand-new 23.8 inch FHD 1920 x 1080 in-cell touch panel for the Asus ExpertCenter P400 AiO 24, model P440VA and its touch builds P440VAES / P440VAEST, IPS, anti-glare, 250 nits, 75 Hz, 30-pin LVDS plus a separate 6-pin USB touch lead. Two checks before you order: this fits the touch build only — the non-touch P440VA uses a different panel that runs at 100 Hz and has no touch lead — and the suffix matters, because the other codes we stock are 60 Hz panels built for Lenovo all-in-ones. Every unit is double tested before shipping and covered by a 30-day return window on unused, uninstalled parts.
- Fit: The 23.8 inch FHD in-cell touch panel for the Asus ExpertCenter P400 AiO 24 — model P440VA in its touch configurations, sold as P440VAES and P440VAEST . 30-pin LVDS connector at the bottom left of the panel, plus a 6-pin USB lead for touch, matte anti-glare surface, 75 Hz
- Panel: an IPS panel, 1920 x 1080, matte anti-glare, 250 nits, running at 75 Hz, with an in-cell touch layer and its own 6-pin USB touch lead alongside the 30-pin LVDS display connector. In-cell means the touch sensor sits inside the LCD cell: there is no separate digitizer glass to lift, and the surface you touch is the panel's own 3H-coated cover
- Testing: every unit is double tested before shipping — display check at full resolution, touch check across the full surface, and fitment check against the machine it is sold for
Technical Specifications
| Item | Detail |
|---|---|
| Machine this panel is sold for | The Asus ExpertCenter P400 AiO 24 — model P440VA, in its touch configurations, which ASUS lists as P440VAES and P440VAEST. Order codes we have seen on the touch build: P440VAEST-BPD054X and P440VA-BPD046X (90PT03X6-M0CNE0). Touch build only — the non-touch configuration of the same machine is a different panel, covered in the last two rows |
| Part numbers | The one number that settles it is the label on the back of the panel you are removing: read it, photograph it, and send it to us if in doubt |
| Condition | Brand-new, unassembled |
| Quality | iProGadgets OEM Quality |
| Size and resolution | 23.8 inches diagonal, 1920 x 1080 (FHD), 16:9, about 92 PPI. Active area 527.04 x 296.46 mm |
| Panel technology | a-Si TFT-LCD, IPS, normally black, transmissive, with WLED edge backlighting along the bottom edge (15S4P, 30,000 hours) and no separate backlight driver. 16.7 million colours, 89/89/89/89 viewing angles, 14 ms grey-to-grey. IPS is what makes this panel usable as a touch screen at an angle rather than straight on |
| Surface finish | Matte anti-glare, haze 25%, hard coating 3H. Every source agrees on this one, which is unusual in this family and worth saying: the anti-glare finish is what keeps a 24 inch touch panel readable in an office with windows, and it is also why finger marks wipe off rather than smear. Clean it with a dry microfibre cloth, never a solvent |
| Brightness and contrast | 250 cd/m² typical, contrast 1000:1 typical. This is the one figure every document states the same way — panel record 250 cd/m², machine page 250 nits — so there is nothing to reconcile here. It is a normal office-brightness panel, not a 400 nit outdoor screen |
| Colour | 72% NTSC, which the panel record puts at 95% sRGB coverage (and 73% Adobe RGB, 75% DCI-P3). The ASUS page for the machine states sRGB 100%. Those are the panel's own measurement and the machine's marketing figure for the same glass, and they are close rather than contradictory — but we print both rather than pick the flattering one. Expect a good, ordinary office colour range; this is not a wide-gamut editing panel |
| Refresh rate | 75 Hz. This row decides whether the listing is yours. The P440VA range was sold with more than one 23.8 inch FHD panel in the same chassis: the touch build runs at 75 Hz and is what this listing is, while the non-touch build runs at 100 Hz and is a different part. Some regional ASUS pages also carry an older P440VA row at 60 Hz / 72% NTSC. Check what your machine reports under Settings, System, Display, Advanced display — 75 Hz with touch working means this panel |
| Touch | Yes — in-cell touch, 10 points. The touch sensor is integrated into the LCD cell, so there is no separate digitizer sheet and no air gap between glass and panel. The controller is on the panel and talks to the machine over its own 6-pin USB lead, which in practice is the single most important thing to remember at installation: the screen will show a picture with that lead unplugged, and the touch will simply not respond |
| Display interface | LVDS, 2 channels, 8-bit, 30 pins, at the bottom left as you look at the back of the panel. The metal latch lifts before the connector slides out — pull the plug body, never the cable. This is LVDS, not eDP: an eDP panel from a newer all-in-one will not connect to it even where the size matches |
| Touch interface | 6-pin USB (YEONHO 10035WR-H06D, 1.0 mm pitch), separate from the 30-pin display connector, at the bottom left as well. Seat this one first when you reassemble, because it sits closer to the frame and is harder to reach once the LVDS plug is in |
| Outline and mounting | 3-side borderless, 535.12 x 313.12 x 12.76 mm overall, weight about 1.93 kg. Fixed from behind through 13 M3 mounting holes in a rear frame — there are no side brackets and no adhesive, so the panel is not bonded into the housing the way a tablet screen is. Handle it by the frame edges and never press on the glass |
| Power | 5.0 V typical, supplied over the LVDS connector. No separate inverter and no high-voltage lead — this is LED backlit |
| Operating temperature | 0 to 50 °C operating, -20 to 60 °C storage |
| NOT the non-touch build | The non-touch configuration of the same P440VA. Same 23.8 inch size, same chassis, same 1920 x 1080 — and a different panel that runs at 100 Hz, has no touch layer, and has no 6-pin USB lead at all. It appears on ASUS order codes such as P440VAK-BPCJ22X (90PT03X6-M09830). The two do not interchange in either direction, and this listing is not an upgrade path for a non-touch machine: there is nothing on the board to plug the touch lead into. If your machine reports 100 Hz and has never responded to touch, stop and send us the panel label |

Before We Ship — Please Send Us These 2 Details
The P440VA was sold with both a touch and a non-touch 23.8 inch panel in the same chassis, and they are different parts. After you place the order we will contact you for the two items below, so please have them ready:
- Confirm your machine is the touch version. Open Settings, System, Display, Advanced display and read the refresh rate: the touch build reports 75 Hz, the non-touch build reports 100 Hz. You can also check Device Manager under Human Interface Devices for a touch screen entry. If your machine is non-touch, this is not your panel and we would rather tell you before dispatch.
- A photo of the label on the back of the old panel. The label carries the panel code, and it is the only reliable identification. It also settles the suffix question, which the model name on the machine cannot.
We check your photo against our stock before dispatch. If something does not match we will contact you first instead of sending a part that may not fit. Once your details are confirmed we arrange shipment within 1 to 3 business days. Thank you for helping us get it right.
Installation Notes
- Unplug the AC adapter and hold the power button for a few seconds so the board discharges. An all-in-one holds charge in its power supply long enough to damage a panel that is unplugged live.
- Remove the stand first, then the rear cover. On this family the cover unclips around its edge; work with a plastic pry tool, not a screwdriver, and keep the clips warm if the room is cold.
- With the cover off you are looking at the back of the panel in its front frame. Note where the two leads run before you release anything — the routing is tight and it is easy to pinch a cable on reassembly.
- Release the 30-pin LVDS connector at the bottom left: lift the metal latch, then pull the plug body. Never pull the cable.
- Release the 6-pin USB touch lead as well. There are two connectors on this panel, not one, and forgetting the second is the most common reason a replacement screen shows a perfect picture with dead touch.
- Undo the mounting screws and lift the panel out by the frame. Do not press on the glass to get leverage, and do not flex the panel — the in-cell touch layer is part of the glass stack and does not survive a bend.
- Clean the flex contacts with alcohol before assembly and confirm both connectors are fully seated and latched. Test the panel and the touch before you refit the rear cover.
- In Windows, confirm the resolution reads 1920 x 1080 and that touch responds across the whole surface including all four corners. Only then reassemble.
- Keep the protective film on until everything works. Handle the screen carefully, because the panel is too fragile to take pressure on its face.
Quality Control
Strictly tested by the iProGadgets QC Team — every unit is double tested before shipping and ships in good working order, including a display check at full resolution and a touch check across the full surface. After receiving the part, please check the appearance and test it first: connect the panel and the touch lead to the machine for a functional test before full installation, and only reassemble once everything works. We are not responsible for any installation mistakes — if you are not experienced with all-in-one screen replacement, have the part fitted by a professional repair shop.
Shipping
We ship worldwide. Orders are dispatched within 1 to 3 business days, and every package carries a tracking number you can follow on the order page. Delivery typically takes 7 to 10 days after dispatch.
Returns & Warranty
30-day returns on unused, uninstalled parts. The warranty is valid until installed — once a screen has been fitted, the return window no longer applies, which is why we ask you to test before installation.
FAQs
Is this the touch panel or the non-touch one?
This is the touch panel, 75 Hz, with an in-cell touch layer and a 6-pin USB lead. The same P440VA chassis was also sold with a non-touch 23.8 inch FHD panel at 100 Hz, which is a different part with no touch layer and no touch lead. They are not interchangeable in either direction. The quick test: Settings, System, Display, Advanced display — 75 Hz and touch working means this listing, 100 Hz and no touch means you need the other panel. Send us the label photo and we will tell you which one you have.
How do I check that this is the screen I need?
Three checks, none of them needing tools. First, the refresh rate: 75 Hz for this panel, 100 Hz for the non-touch build. Second, the label on the back of the panel you are removing, and the trailing suffix is what matters,Third, the machine: it should be an ExpertCenter P400 AiO 24, model P440VA, in its touch configuration (P440VAES / P440VAEST). Photograph the panel label and the machine label and send both to us; we match them against stock before dispatch rather than after.
The picture is perfect but the touch does nothing — what went wrong?
Almost always the 6-pin USB touch lead. This panel has two connectors: the 30-pin LVDS that carries the picture and a separate 6-pin USB lead that carries the touch data. The screen lights up and displays correctly with only the first one connected, which is exactly why the second gets missed. Open the machine again, reseat that lead at both ends, and check Device Manager under Human Interface Devices for a touch screen entry. If it is still dead with the lead properly seated, contact us — a failed touch controller is covered, and we will sort it out rather than leave you with half a screen.

Frequently Asked Questions
Is this part compatible with my device?

Match the model number in the title against your own device before ordering. If you are not sure which version you need, email sales@iProGadget.com and we will confirm the correct part for you.
What is the quality of these replacement parts?
We supply iProGadgets OEM Quality / Premium Compatible replacement parts. Every part is manufactured to OEM specifications, so the fit, finish and function match the original component it replaces, and each unit is individually tested before it leaves our warehouse.
Is the part tested before it is shipped?
Yes. Every part we sell is inspected before dispatch and tested wherever testing applies — screen assemblies are checked on the panel, the touch response and the connector. Orders are processed and shipped within 1-3 business days after payment is confirmed.
How long does shipping take?
Orders leave our warehouse within 1-3 business days. Express Shipping (DHL, UPS or FedEx) takes 5-8 working days and is normally used for parcels over 2 kg. Registered Air Post takes 10-20 working days and is normally used for parcels under 2 kg. Every order ships with a tracking number. Customs clearance can add extra time, especially during peak season.
Will I be charged import duties or customs fees?
Customs charges depend on your own country's import rules and its de minimis threshold, not on the seller. Some destinations apply no duty at all on lower-value parcels, and where duty or VAT does apply it is collected by your local post office or courier before delivery. We ship every order with complete and accurate commercial documents, which is what keeps a parcel moving through customs instead of sitting in it. If you would like to estimate the charges before you order, email us your country and we will point you to the right authority.
What is your return policy?
We offer a 30-day return policy, which means you can request a return within 30 days of receiving your item. To be eligible, the item must be unused, uninstalled and in the packaging it arrived in. Once a part has been fitted, bonded or used it cannot be returned, so please test the part before installation. To start a return, email sales@iProGadget.com.
What should I do if the part arrives damaged or faulty?
Inspect your order as soon as it arrives. If an item is defective, damaged or not what you ordered, contact us at sales@iProGadget.com straight away with photos or a short unboxing video, and we will arrange a replacement or a refund.
Do you provide repair guides or installation tutorials?
No. We are a supplier of replacement parts only. We are not a repair shop, and we do not provide repair guides, tutorials or step-by-step installation support. Every part we sell is intended to be installed by a professional technician at a qualified repair shop, which also gives the best result: a technician can transfer the small components, handle the adhesives and test the finished repair. Please do not attempt the installation yourself if you have no previous repair experience, as these assemblies are fragile and incorrect handling can damage them permanently. We sell parts only and do not accept responsibility for installation carried out by the customer. Our warranty covers the part itself and remains valid until the part is installed. If a problem appears after the repair, please take the device back to the repair shop that fitted the part so they can inspect the installation and test the device.
Still have a question about this part? Email us at sales@iProGadget.com and we will confirm compatibility, shipping time or return details for you.
