Poco X4 GT Screen Replacement Vienna
Your Poco X4 GT suddenly shows layer tearing in 144 Hz mode while gaming – horizontal blocks of the picture visibly shift in FPS titles, racing games or during fast scrolling. Drop back to 60 Hz and everything runs cleanly again. It is a classic gaming-panel fault, where the 144 Hz sync of the 6.6-inch IPS LCD no longer stays in step. Reparo replaces the complete display module in Vienna – EUR 139 fixed price, done in 1–2 hours, with a 6-month warranty.

What to expect from your Poco X4 GT screen replacement
The Poco X4 GT is gently warmed at the back cover and opened, the 6.6-inch IPS module is freed from the mid-frame and replaced with a tested spare module that supports the full 144 Hz DynamicSwitch rate. We pay particular attention to the sync lines between the mainboard and the new panel sitting perfectly clean – any imperfection shows up later while gaming.
Usually 1–2 hours of repair time from the moment the device reaches the workshop. With pickup in Vienna you normally get your Poco X4 GT back the same working day, in time for the evening session. For mail-in from other regions: 1–3 business days after arrival, including insured return shipping.
The 144 Hz gaming display runs again without layer tearing, fast movements in FPS or racing games are rendered cleanly, and the touch responds with the low latency gamers expect. The 5080 mAh battery cell, the 67 W USB-C charging port, the cameras and all sensors stay untouched during a screen replacement.
EUR 139 fixed price – including the complete IPS LCD module, fitting, a sync test at every refresh stage and a 6-month warranty. The diagnostic check (EUR 25) is fully deducted from the repair price once you place the order. The final total is confirmed in writing before the first turn of the screwdriver.
Typical Poco X4 GT display faults
Horizontal blocks of the picture shift during fast scenes in Call of Duty Mobile, Asphalt 9 or PUBG. One block at the top stays a frame behind while the lower part has already moved on. At 60 Hz the problem disappears – a clear sign that the 144 Hz sync inside the panel is disturbed.
The flat 6.6-inch panel of the Poco X4 GT is sturdier than a curved AMOLED, but on impact with asphalt the glass and LCD often break together. Typical: a star-shaped crack spreading from the point of impact and milky patches from the leaking backlight.
The picture runs smoothly, but inputs arrive with a noticeable lag – in competitive games that is the difference between a win and a loss. The digitiser in the IPS panel has a broken trace, usually after a drop or from pressure on the display in your pocket.
The Poco X4 GT shows one or more thin bright or dark lines running across the panel. On IPS LCDs such lines come from torn source lines after pressure or a fall. A restart changes nothing – the panel has to be replaced.
When you launch gaming apps with a black background, milky patches of light appear along the edges of the 6.6-inch display. After an impact the backlight of the IPS panel pushes through unevenly – a typical IPS fault that a module replacement fixes.
The Poco X4 GT starts normally, but when it switches into 144 Hz gaming mode the screen stays black. The device still reacts to calls and notifications. A flex connector between the mainboard and the panel is no longer stable during the refresh-rate switch – a module replacement restores the function.

How the Poco X4 GT screen replacement works
-
Book pickup in Vienna or mail-in Austria-wide
Reserve a slot online through the booking form or by phone on +43 677 62801426. In Vienna we collect the Poco X4 GT at the address you choose – at home, at work or at a meeting point. From other regions the mail-in address arrives by email after booking.
-
Gaming-panel diagnosis with a refresh-rate test
We check the Poco X4 GT specifically for the 144 Hz sync: test images with horizontally moving patterns, refresh-rate switching between 60, 90, 120 and 144 Hz and a touch-latency test. The diagnostic check costs EUR 25 and is fully waived as soon as you place the repair order.
-
Open the back cover and remove the IPS module
The back cover is warmed, carefully lifted and the 5080 mAh battery cell is disconnected. We free the faulty IPS panel from the plastic mid-frame, clean off all adhesive residue and inspect the condition of the flex connectors to the mainboard. Typical on the X4 GT are small dust deposits at the vent from intense gaming sessions.
-
Fit the tested 144 Hz IPS panel
The new 6.6-inch IPS LCD is set in place with fresh frame adhesive, all flex cables are clipped onto the mainboard and the battery cell is reconnected. We pay particular attention to the sync line for the refresh-rate switching sitting tight – the smallest deviation otherwise leads to layer tearing later while gaming.
-
Gaming stress test at full 144 Hz
The Poco X4 GT is started and the panel runs through a stress test with fast motion patterns at 144 Hz. We check touch latency with a tap-test tool, run a short gaming benchmark and verify 67 W fast charging and the fingerprint sensor on the frame. Everything documented.
-
Return with a 6-month warranty
The repaired Poco X4 GT is handed back at your address in Vienna or returned by insured parcel. You get a 6-month warranty on the panel and the fitting – should layer tearing, touch dropouts or pixel faults appear within that time without a new drop, we fix it free of charge.
No walk-in option – the whole process runs through the pickup service in Vienna or by mail-in post.
Is a screen replacement worth it on the 4-year-old Poco X4 GT?
The Poco X4 GT launched in 2022 as gaming mid-range and was one of the first devices in this price class with a 144 Hz IPS panel and 67 W fast charging. Four years on, the hardware is still strong enough for mobile gaming sessions: Call of Duty Mobile, Genshin Impact, PUBG or Asphalt 9 run smoothly on medium to high settings. For EUR 139 you get a fresh 144 Hz panel and keep your well-tuned gaming device. A current Xiaomi 14 starts new from around EUR 899.
- EUR 139 fixed price – incl. fitting and warranty
- Game progress, gaming accounts and MIUI profile stay
- 6-month warranty on the panel and the fitting work
- Done in about 1–2 hours
- 144 Hz gaming performance stays fully intact
- 67 W fast charging and 5080 mAh battery untouched
- From around EUR 899 – Xiaomi 14 brand-new device
- Set up Google Play logins and gaming accounts again
- Restore game progress in every app individually
- Sell or properly dispose of the old device
- Different display size, different feel in the hand
If the Poco X4 GT is your main gaming phone, the swap for EUR 139 almost always pays off. The 144 Hz DynamicSwitch technology in particular is hard to find in this price class today – many current mid-range devices are capped at 120 Hz.
Which display does Reparo fit in the Poco X4 GT?
We fit a tested 6.6-inch IPS LCD complete module with full 144 Hz DynamicSwitch support – an exact match for the original Poco X4 GT panel. The glass and IPS layer are factory-bonded on the Poco X4 GT, so we always replace the entire module and never just the front glass. Every panel goes through a sync test at all refresh-rate stages (60, 90, 120, 144 Hz) and a touch-latency test targeting under 10 milliseconds before fitting. A fresh adhesive ring is used on the frame so the new panel sits flush and no dust deposits build up during gaming sessions.
Poco X4 GT display faulty – what now?
The Poco X4 GT was a clear statement in 2022: gaming performance in the mid-range with no compromise on the display. The 6.6-inch IPS panel with 144 Hz DynamicSwitch was a rarity in this price class – most rivals delivered 120 Hz at most, and often only on pricier AMOLED models. It is exactly this gaming focus that keeps the X4 GT relevant today: for casual gamers and mobile eSports players the hardware is enough, as long as the panel plays along. But when layer tearing suddenly appears during fast gaming – horizontal blocks shifting against each other – then the 144 Hz sync of the panel is faulty. In 60 Hz mode everything runs cleanly again, but the gaming advantages are lost.
The repair at Reparo runs entirely without a shop visit: lock in a slot online or by phone, and the Poco X4 GT is collected in Vienna or sent in by parcel from Lower Austria, Upper Austria, Styria, Carinthia, Salzburg, Tyrol, Vorarlberg or Burgenland. You will find more about the model and every repair on the Poco X4 GT model page.
Why 144 Hz panels fail differently from 60 Hz displays
A 144 Hz gaming panel refreshes the picture 144 times per second – more than twice as fast as a standard display. That demands clean synchronisation between the GPU and the display controller. When the panel controller is faulty, individual frames arrive late while others have already moved on – exactly the visible layer tearing you notice when scrolling fast lists, in FPS games or in racing titles. At 60 Hz the sync tolerance is far higher, which is why the picture often still works there without trouble. The repair therefore needs a tested 144 Hz replacement panel that matches the sync specification of the original exactly – a simple 60 Hz swap would be a downgrade.
Gaming focus and DynamicSwitch – what makes the Poco X4 GT special
The Poco X4 GT uses a technology called DynamicSwitch: depending on the content, the panel automatically switches between 30, 60, 90, 120 and 144 Hz. In menus and while reading the rate stays low to save battery – while gaming it jumps to 144 Hz for smooth rendering. This automatic switch is often the very point where panels develop problems after heavy use. The 5080 mAh battery and the 67 W fast charging are not affected by a screen replacement, and the side-mounted fingerprint sensor on the power button stays untouched and needs no recalibration.

Frequently asked questions about Poco X4 GT screen replacement
Poco X4 GT screen replacement — what does it cost at Reparo?
EUR 139 fixed price – including a tested 6.6-inch IPS LCD with full 144 Hz DynamicSwitch support, professional fitting and a 6-month warranty. The diagnostic check (EUR 25) is deducted from the repair price when you place the order. The final price is confirmed in writing before work begins – no surprises.
Does the 144 Hz gaming rate stay after the screen replacement?
Yes. We only fit replacement panels that support the full 144 Hz DynamicSwitch specification of the original. A downgrade to 60 or 90 Hz is out of the question for us – the gaming display is precisely what sets the Poco X4 GT apart. After the swap we test all refresh-rate stages with stress patterns.
How long does the screen replacement on the Poco X4 GT take?
About 1–2 hours of pure repair time from arrival at the workshop. With pickup in Vienna you usually get the Poco X4 GT back the same working day – in time for the evening gaming session. For mail-in from other regions: 1–3 business days after arrival, including insured return shipping.
What is layer tearing and why does it happen on the Poco X4 GT?
Layer tearing is horizontal blocks of the picture that appear shifted against each other – especially visible during fast movements in FPS games or while scrolling. On the Poco X4 GT the problem arises when the 144 Hz sync controller in the panel no longer works cleanly. In 60 Hz mode the tearing often disappears, in 144 Hz gaming mode it stays visible. A module replacement fixes the cause permanently.
Does the Poco X4 GT have an AMOLED or an IPS display?
The Poco X4 GT uses a 6.6-inch IPS LCD panel – not AMOLED. That is typical for mid-range gaming devices, because IPS panels are more resistant to burn-in during long sessions with static HUDs and are also cheaper to produce. Typical IPS damage: cracks, milky patches, horizontal lines – not the ink-like black blotches AMOLEDs show after a break.
Does the fingerprint sensor still work after the screen replacement?
Yes, fully. The Poco X4 GT fingerprint sensor sits on the side in the power button – not under the display like on many AMOLED models. During the screen replacement it is not touched, so saved fingerprints, calibration and unlock speed stay unchanged. No re-enrolling of fingers is needed after the repair.
Can I drop the Poco X4 GT off for repair?
Reparo works without a shop and takes no walk-in customers. Everything runs exclusively through the pickup service in Vienna or by postal mail-in from anywhere in Austria. That cuts fixed costs and lets us offer a more affordable fixed price on the 144 Hz screen replacement – running a shop would make this price impossible.
How exactly does the Vienna pickup service work for the Poco X4 GT?
You book a time slot online or by phone and give a Vienna address – home, office or a meeting point of your choice. We come at the agreed time, take the Poco X4 GT to the workshop, replace the panel in 1–2 hours and then bring the device back to the same address. You do not have to travel anywhere.
Can I send the Poco X4 GT in from the other regions?
Yes, from Lower Austria, Upper Austria, Styria, Carinthia, Salzburg, Tyrol, Vorarlberg and Burgenland. After booking you receive the mail-in address and packing instructions by email. Insured return shipping is already included in the EUR 139 fixed price. Turnaround: 1–3 business days after the item arrives, repair included.
Will my game progress and gaming accounts be lost during the repair?
No. During the Poco X4 GT screen replacement only the panel is replaced – the internal storage with all game progress, Google Play and Mi accounts, apps and MIUI settings stays completely untouched. A backup via Xiaomi Cloud or Google Drive before sending in is still a sensible precaution for important gaming progress.
What warranty is there on the new 144 Hz panel?
A 6-month warranty on the panel and the fitting work. Repair-related faults – such as recurring layer tearing at 144 Hz, pixel faults, touch dropouts or loose flex connections without a new drop – are fixed free of charge within this period. New damage from a drop, pressure or water contact is not covered.
Original panel or aftermarket on the Poco X4 GT?
For the Poco X4 GT we fit a high-quality IPS LCD aftermarket module with full 144 Hz DynamicSwitch support. Original Xiaomi spare parts are barely available in the parts trade for this model. The aftermarket panel matches the original in refresh rate, brightness and touch latency – every swap is tested at all refresh stages before delivery.
Is a screen replacement still worth it on the 4-year-old Poco X4 GT?
If you use the Poco X4 GT as a gaming phone, the swap almost always pays off. The 144 Hz DynamicSwitch technology is still strong in this price class even in 2026 – a current mid-range device with comparable gaming performance costs significantly more new. A Xiaomi 14 starts from around EUR 899. A EUR 139 screen replacement is the clearly more economical decision.
What does the diagnosis cost if I do not order a repair?
The diagnosis on its own costs EUR 25. If you then decide on the screen replacement, this amount is fully deducted from the EUR 139 repair price – so you only pay it once. With visible layer tearing or a cracked panel, the diagnosis including the refresh-rate test is usually done in 15–20 minutes.
What if the Poco X4 GT has failed after water contact?
The Poco X4 GT has no IP rating against moisture. After water contact we first check whether only the display or also the mainboard, the 5080 mAh battery cell and the 67 W USB-C charging port are affected. The board is cleaned in an ultrasonic bath if needed before the new panel is fitted. Initial diagnosis: EUR 25 – waived on repair.
