How to know exactly which display is on the Xiaomi Redmi Note 8 Pro: original or copy?

Owners of the Xiaomi Redmi Note 8 Pro often face the need to determine the model of the installed display — especially after repairing or buying a used device. The reasons can vary from suspicion of a non-original spare part to checking for firmware compatibility. The display in this model is one of the most vulnerable components, and the market is full of copies of different quality. Without accurate information, you risk incorrect color reproduction, sensor problems or even damage to the motherboard if incompatible.

In this article, we will explore all the working methods of screen identification, from software methods to visual analysis. FT8719 It's all about fakes, what codes are put into the engineering menu, what the labels on the plume mean, and why some displays, when they're replaced, are curved, even when they're externally identical.

1. Checking through phone settings: a fast but inaccurate method

The easiest way is to look at the system information of the smartphone, MIUI It doesn't display the display model directly, but some indirect data may be a concern. → The phone. → Version. MIUI and tap 7 times on the kernel line to activate developer mode. Then go back to the basic settings and go to the new developer section.

Here, pay attention to two parameters:

• 🔍 Screen density (400 dpi for the original) If the value is different (e.g. 380 dpi), this may indicate a non-original matrix with a different resolution.
• 🎨 Color profile: Original displays support sRGB and Display P3, Copies are often limited to basic RGB.

⚠️ Note: These parameters are easy to forge software, especially if the phone has been stitched with custom firmware. For example, some Chinese copies emulate density. 400 Dpi, but they have a valid resolution. 2280×1080 instead of original 2340×1080. Additional methods will be required for accurate verification.

2. Engineering menu: hidden data about the display

A more reliable way is to use the Engineering Mode.

1. Open the Phone app.
2. Enter the combination: ##36446337##
3. Select Version Info (or Hardware Testing in some versions of the firmware).

In the menu that opens, find the sections:

• 📱 LCD Version – This may display a matrix model (e.g, FT8719 original).
• 🔧 Touch Panel Version - Touch layer version (must match the display).
• 🎯 TP Firmware – touchscreen firmware (non-original displays often have outdated versions).

If you see Unknown instead of a specific model, or a set of numbers without lettering, that's a sure sign of a non-original spare part. It's also worth checking the color calibration in the engineering menu: the original displays show DeltaE. < 3, and copies of this parameter is usually higher.

Physical examination: markings and external signs

If the software methods fail, you'll have to take the phone apart. Attention: this cancels the warranty (if it's still valid) and requires care. You'll need a plastic spatula, a screen suction cup and a hair dryer (to soften the glue).

After removing the display, examine:

1. The screen plume should have a labeled sticker on it. The original Redmi Note 8 Pro displays have the inscriptions: 🏷️ Tianma FT8719 or FT8719 FHD+ (Main supplier to Xiaomi). 🏷️ HSD or HSD S60 (alternative). 🚫 BOE, JDI, AUO — These markings are found on copies (although they are not available). BOE Sometimes it is available for other Xiaomi models).

Date of production

20W35

Assemblance quality

A critical sign of fake: If the plume has the words "For Samsung" or "Compatible with Note 8 Pro" on it, it is a 100% unoriginal spare part, often with a screen yellowness problem.

💡

If you are buying a Redmi Note 8 Pro, check the display for burnout. Turn on a clean white background on the phone (like in the Colors app) and light up the flashlight at an angle. The original displays have no visible wear even afterward. 2-3 years of use, and copies often fade in places of static icons (for example, navigation panels).

4. Specialized applications for diagnostics

If you don't want to take your phone apart, use the display testing apps, which won't show you the matrix model, but will help you identify problems that are common with non-original screens:

• 📱 Screen Test (from Keuwlsoft) - checks broken pixels, gradients and color reproduction. the original display should not have visible defects on the Color Bars test.
• 🔍 Display Tester – analyzes the response to touch (delays over 50 ms indicate a non-original sensor).
• 📊 AIDA64 — In the Display section, you can see resolution and density. Compare it to the original settings: 2340×1080 upon 400 PPI.

⚠️ Attention: Some applications (e.g, CPU-Z) They can show incorrect display data if the phone is rooted or stitched with custom Recovery. 2-3 Programs and compare results.

Pay special attention to the screen flicker test (turn on the front camera and shoot the display on video - the original matrixes do not flicker at a frequency above 200 Hz). Copies often have noticeable flickering even at 60 Hz, which leads to eye fatigue.

Check compatibility with the Redmi Note 8 Pro (begonia code)

Check the seller's marking on the plume (should be) FT8719 or HSD)

Ask for a photo of the display with a white background on (whether yellowness is not)

Make sure that the kit comes with a new adhesive layer (original displays come with a 3M LOCA)

Compare the price to the average market (original costs from 8000) ₽, copies from 3,000 ₽)

5. Problems of non-original displays: what awaits you?

Even if a copy of the display is indistinguishable from the original, it can show up over time.

• 🔥 Overheating – non-original matrices often consume more power, leading to processor heating and quick battery discharge.
• 🎨 Distorted colors – copies rarely undergo color calibration, so photos and videos look unnatural (for example, the skin of the face gives green).
• 👆 "Ghost touches – the sensor responds to touch on its own, especially in high humidity.
• 🔋 Reduced running time – Unoptimized drivers make the display consume up to 20% of the extra energy.
• 📉 Artifacts when scrolling – horizontal stripes or “breaks” of the image appear.

The most dangerous problem is incompatibility with updates MIUI. After new versions of the firmware are released, the non-original displays may stop working completely or start to flicker. MIUI 14 Many users with copies of screens encountered an error EDID Mismatch that blocks the image.

If you have already installed a non-original display, avoid firmware updates via OTA. It is better to use manual firmware with compatibility checks disabled (for example, through XiaomiFlash with the option). clean_all_lock).

💡

The original Redmi Note 8 Pro display has a unique identifier in the firmware. If after changing the screen, the phone stopped detecting brightness automatically or there were problems with Always-On Display, this is a sure sign of a non-original matrix.

6. Where to buy the original display and how not to run into a fake?

The original displays for the Redmi Note 8 Pro are sold under the following articles:

• MDY10-00021 — Full module with frame and sensor (Tianma) FT8719).
• MDY10-00022 — alternative HSD (less).

Checked places to buy:

• 🛒 Xiaomi official service centers – the guarantee of the original, but the price is higher than the market 30-50%.
• 🌍 AliExpress – look for sellers with a rating above 98% and reviews in English (Chinese reviews are often fake.
• 🔧 Local repair shops – some buy original parts in bulk and sell at a small margin.

⚠️ Warning: Markets like Avito or Yula often sell "originals" for the price of a copy:

• 📸 No photo of the plume with the marking - 90% that it is fake.
• 💬 The description contains phrases like “100% as original” or “indistinguishable from native” – these are markers of the copy.
• 🔄 The seller refuses to provide video with a display test (for example, a color rendering check).

If you are buying a display for self-replacement, make sure that the package comes with:

• 🧲 New adhesive layer (better) 3M LOCA or B-7000).
• 🔧 Tools for removal (suction, shoulder blade).
• 📄 Guarantee card (even from Chinese sellers on AliExpress).

7. Self-replacement of the display: risks and recommendations

Replacing the display with the Redmi Note 8 Pro is a medium-sized repair. If you don't have experience, it's best to contact the service - disassembly errors can lead to:

• 🔌 Damage to battery plume (phone will not turn on).
• 📶 Loss of antenna signal (if you touch metal frames).
• 💥 Battery fire when connected incorrectly.

If you are planning to do a repair, follow this algorithm:

1. Turn off the phone and remove it. SIM-map.
2. Heat the edges of the screen with a hair dryer (temperature not higher than 60°C) to soften the glue.
3. Carefully tuck the display with a plastic spatula, starting at the bottom edge.
4. Disconnect the battery plumes and display (use insulation tweezers!).
5. Install a new display, connect the plumes and check the operability before applying the glue.

⚠️ Critical error: Never turn on a phone with a display plugged in, but without a battery! This can burn the power controller. Always plug in the battery first, then the display plume.

After replacement:

• Check the Always-On Display (copies often don’t work).
• Calibrate the sensor in the engineering menu (#6484##).
• Update the touchscreen firmware via Fastboot (if the sensor is buggy).

💡

If the phone starts to discharge quickly after replacing the display, check the brightness settings. Non-original matrices often have an understated maximum brightness (for example, 350 thread 500 The original thread, which makes up for this with the increased power consumption. 60-70% smack-in.
