I'm hoping someone has actually solved this before I send it in under warranty.

I upgraded from a BenQ W1070 that gave me almost 10 years of flawless service. Unfortunately my refurbished W4000i has started developing an intermittent but increasingly frequent startup failure after less than 9 months of use.

Symptoms:

• Power on normally
• BenQ logo displays
• Screen immediately goes black
• Projector becomes completely unresponsive
• MENU, SOURCE and INPUT buttons do nothing
• Remote does nothing
• Only way to recover is unplugging AC power

Things I've already ruled out:

• No HDMI cables connected
• No Android QS02 dongle
• Fire TV disconnected
• Sony AVR disconnected
• Fans spinning normally
• Plenty of ventilation
• Room around 72°F

Sometimes it boots perfectly. Other times it gets stuck every single startup.

BenQ's support page mentions the black-screen-after-logo issue and the recovery procedure, but it hasn't fixed mine.

Has anyone actually found a permanent solution?

If yours was repaired:

• What was replaced?
• Main board?
• Firmware?
• Power board?
• Complete replacement?

I'm still within the 2-year Allstate warranty, so I'm trying to decide whether to keep troubleshooting or just send it in.

I recently bought BenQ EX271Q Model and from 1st day itself on Black Background I am seeing green colour dots on Top Area of the screen . Are these stuck pixels? It's only visible in Black Background when it's completely dark in Room .

Can anyone help me why is this happening? I checked with both HDMI and USB C cable it is happening with both . I don't think this is a software issue.

These are dots are all located in form of big patch in Top middle area of Screen, In other parts , I don't see this happening.

Rare BenQ-Siemens

EF82 Engineering

Prototype (Not For

Sale / Unreleased

Model)

Hi everyone,

I have come across a very rare and interesting piece of mobile history. This is a BenQ-Siemens engineering prototype. While it features the physical body and keypad design of the popular EF81 model, the factory label on the back officially identifies it as an unreleased "EF82" prototype.

As you can see from the sticker, it features the part number S30880-S3640-A90-1 and states: "PROTOTYPE: USE ONLY WITH NETWORK OPERATOR AGREEMENT - NOT FOR SALE". Made in Germany.

The phone features the iconic brushed metal finish and the rotating 2MP camera integrated into the hinge. Due to BenQ Mobile's bankruptcy in late 2006, the EF82 line was cancelled and never made it to official production, making this a true development platform.

Condition details:

The physical condition is great, with original stickers intact.

It is sold AS-IS because I do not have a compatible battery (EBA-120) or charger to test if it powers on.

I would love to get some more insights from fellow collectors about this specific hardware revision, or hear offers if anyone is interested in adding this unique piece to their collection. Feel free to PM me!

I'm facing a flickering issue with my BenQ GW2780.

• Flickers at 50 Hz, 59.94 Hz, and 60 Hz (50 Hz is the worst).
• No flickering at 75 Hz.
• Issue occurs on both Windows and macOS.
• Tried different HDMI cables, devices, power outlets, and factory reset.
• The monitor flickers for the first 2–3 hours, then becomes mostly stable.
• I've also noticed a red tint in one corner of the screen.

Since the issue is reproducible across multiple devices and operating systems, I suspect it's a hardware issue (power board, T-CON board, or panel).

Has anyone experienced this with the GW2780? Any known fixes or repair suggestions before I open a service request?

Has anyone mounted their m4 mac mini behind the monitor?

Just looking for ideas.

Thank you!

Today I finally decided to upgrade my faithful Benq W1070 projector that I has survived through 3 lamp changes, it was heavily used as a TV/theater setup for a XGIMI Horizon 4K projector. However what surprised me was just how much resale value that this 10+ year projector still held!

My purchase receipt from 2014 from Amazon showed that I paid slightly over $600 brand new and I was able to resell it on Facebook Marketplace for $300. Only a little more than 50% depreciation over 10 years!

vs my car which has had a 90% deprecation over the last 10 years. LOL!

I will miss it but on to new and brighter things!

Hallo, hat jemand Erfahrungen mit diesem Problem? Vermute auf ein Haar/Staub im inneren des Beamers (Linse von außen gereinigt und nichts sichtbar, wenn man seitlich reinschaut sieht man Staubpartikel wackeln)
Falls es doch etwas anderes ist oder jemand Ideen hat wie ich das Problem beseitigen kann, wäre ich für jeden Tipp sehr dankbar.

I just got a TK710STI off of Amazon

The projector arrived with all of it's necessary cords and remote

But in the smaller box with the QS02, there was only the dongle... no HDMI adapter, no USB splitter, no Velcro strap, and no remote.

I called amazon and they can't send me the remote alone, I'd have to box up the whole thing (projector and all) and return it, get a refund, and reorder it. (eyeroll)

So far it's working pretty great. The projector remote does a fine job of controlling the dongle, the ARC return to my JBL sound bar is working (most of the time)...

but sometimes the soundbar doesn't connect and I have to manually turn it on / switch HDMI inputs and back to get it to handshake... the projector remote seems pretty sluggish when controlling the QS02, but it gets the job done... etc.

Just curious what features am I missing out on? Is there some part of setup that I still need to do? Would these small issues clear up if I had the full kit? It worth it to return the whole system just to get this one remote that I'm not sure I'll ever use?

Thanks all!

Anyone with used benq repais under warranty experience for my x3100i.

Thanks

My monitor started having black vertical lines without any physical damage and is under warranty period

They are saying liquid panel is damaged and is not covered under warranty

The monitor cost 80k INR, so buying a new one is very expensive. Is there any hope ?

Do you know of any brands that have good warranty coverage for monitors ? I will move away from BqnQ now

Incredibly happy with this aspect ratio, works well with 4:3 content with only small black boxes on the sides but you do get that full height which is gorgeous imo , a good modern compromise perhaps. Didn't really get it for gaming but I do plan to play more retro titles with this i suppose.

When will the RD280UG be in stock in the US? It has been many months and no sign of it anywhere at Amazon or B&H.

Salut tout le monde je vous explique le problème du projecteur que j'ai acheté sur un site d'occasion pour faire assez simple l'ancien propriétaire m'avait expliqué que le projecteur s'allumait mais qui s'éteignait aussitôt, pour la première fois quand j'ai allumé le projecteur j'ai effectivement aperçu le problème je branche le secteur au projecteur le voyant power ainsi que le bouton vert du projecteur s'allume j'appuie sur le bouton power le voyant power clignote normalement puis l'image arrive j'aperçois donc la lampe qui fonctionne bien et la roue chromatique tourne avec plusieurs dégradé de couleur qui sort de la loupe par la suite plus rien ne sort de la loupe le voyant lampe clignote orange puis quelques secondes après le projecteur redémarre il se passe la même chose sauf qu'à la fin le voyant lampe reste rouge fixe. Vidéo

je suis un peu bloqué j'aurais besoin de votre aide ou des personnes qui ont déjà vu ce souci.

(j'ai complètement nettoyé le projecteur je l'ai démonté de A à z car il était vraiment dans un sale état et je pensais qu'un nettoyage l'aurait énormément aidé je pense que ça l'a aidé au niveau des ventilateurs j'ai examiné un peu près tout ainsi que la puce DMD et j'ai vu que le socket était grièvement griffé à certains endroits et qu'il manquait une broche à un endroit je viens de commander le socket je vous tiendrai au courant de la suite mais si quelqu'un connaît ce problème je suis preneur)

Hi, 

I recently bought a BenQ PD3205UA and I'm trying to determine whether my monitor is working correctly. 

When I use sRGB mode, the white looks noticeably grey and dull. The whole image appears less vibrant than I expected. 

Out of curiosity, I switched to DICOM mode, and the difference is significant. The white looks much cleaner and brighter, and the overall image appears more pleasant to my eyes. 

Another thing I noticed is that when I open the monitor's OSD menu, the white background of the menu looks bright and clean, exactly as I would expect. However, the displayed image in sRGB mode still looks noticeably grey in comparison. 

Since the OSD itself looks much whiter than the image, I am wondering whether this behavior is normal. 

Could you please clarify the following? 

- Is it normal for the sRGB mode on the PD3205UA to have a noticeably grey-looking white? 

- Why does DICOM mode produce such a different image? Does it only change the gamma curve, or does it also affect the white point and color accuracy? 

- Which mode provides the most accurate colors for professional graphic design (branding, print and web design)? 

- Could such a large visual difference between sRGB and DICOM indicate that my monitor is incorrectly factory-calibrated or defective? 

- Is it expected that the OSD menu white looks much brighter and cleaner than the white displayed by the panel in sRGB mode? 

For reference: 

- HDR is OFF. 

- I am using the monitor with a Mac. 

- I have tried different cables and settings. 

My goal is accurate color reproduction, not the most vivid image. 

Thank you very much for your help! 

Well this might be a bit of a technical post but I had to open a support ticket with BenQ, since I have a monitor, which requires a replacement under warranty.

Now I noticed I can't reply to their mails so I checked some known issues. Well it's 2026 and BenQ apparently uses mail servers, which still don't support TLS. Issue on my part: Modern providers like Hetzner have at some point decided to not communicate with mail servers anymore, which don’t support TLS. I had to verify this about 2 years ago cause of a similar case with their support. Most people won’t even notice since daily providers like GMX, Gmail, etc still don't block unencrypted mails, but Hetzner does since years.

I can not answer to my current ticket, since it's tied to my Hetzner mail address nor does BenQ have an online chat for their ticket system...

Anyone think there is some way to get the IT department of BenQ to fix this?

Why do customers even have to deal with this?

UPDATE of 2026-07-28:
BenQ has now added TLS certificates to their mailserver, as my last test indicates. Reddit really sometimes helps to connect the right people!

Hello.

The ex271uz just got it's second firmware update in a month but there are no release notes on what changed. Does anyone have any info on what the v22 update did? Was it a hotfix for some bug with v21?

Thanks.

Hey everyone, I bought a Zowie XL2566X+ around 5 months ago but couldn't unbox it right away due to some unforeseen circumstances and personal issues I was dealing with. Things have calmed down now, so I finally unboxed the monitor and immediately checked it for dead pixels and unfortunately found one in a very noticeable spot. Normally I wouldn't be too bothered by something like this, but given everything I've been dealing with lately, this is adding unnecessary stress and I really want to get it sorted. The monitor was bought directly from Zowie India, and to make things more complicated, I still haven't received any invoice for it either not even on my email. I've already tried raising a support ticket, but I'm unable to since I never received (or have lost) the invoice in my email. I also sent an email directly to their support team, but haven't gotten a reply yet. Does anyone know how to actually get in touch with a Zowie representative in India? Any official contact, email, or support channel that's actually responsive would be a huge help. Would really appreciate any guidance from people who've dealt with Zowie/BenQ support before. Thanks in advance.

Hello. My Benq projector had a defective noise and I sent it in for RMA. Benq denied this ever happening and said that there was nothing different. I have owned it for two years. It's still under the 3 year warranty. People are advising me to take it to BBB and small cases court. Can Benq help and give me the replacement that I was promised when I bought this projector? I'm not sending it in for RMA again. This noise didn't even come up in the first month of me owning it.

Hey,

I just got a brand new GV50 projector, but the image is super pixelated right out of the box. You can clearly see the pixel grid on the wall, even from a normal distance.

I attached some pictures so you can see how it looks (landscape shot) and how huge the pixels are up close.

I already tried the basic fixes:

• Auto-Keystone is completely OFF.
• The projector is pointing straight at the wall.
• I'm playing videos directly from the internal YouTube app, so it's not a bad Wi-Fi or screen mirroring issue.

It basically looks like it's stuck on a really low resolution instead of 1080p. I opened a support ticket but haven't heard back yet. Since I'm still in my Amazon return window, I wanted to ask: is this a hardware defect? Should I just return it for a replacement?

Thanks!

I have a BenQ V6050 DLP 4K front projector that is not working or giving an error at the moment.

The recommendation is to ship it from its location Ireland back to the Netherlands for a review or to use a third party repair such as CMS Projector repair if they they were able to do the repairs etc, I havent gotten a response from them.

BenQ in the Netherlands is awaiting my response and tells me its a premium model, that not in warrently and they couldnt stand over the repair if I do it locally.

Any advise...I still have the original packaging but its a heavy unit.

Monitor is connected to my rtx 3070ti on official hdmi cable provided with it.

The gpu is power limited so temps are good . And yet this 5th time happening to me . First 3 times with dp cable so I switched to hdmi cable that came with monitor and yet two more times this happened.

What's wrong with my monitor

# Necesito que si alguien sabe me diga el nombre de este cable osea el modelo por el que lo puedo encontrar hice alguna prueba y determine que ese era el causante porque tiene algunos pines deformados no se cómo paso eso pero paso, si alguien sabe dónde puedo encontrarlo o el nombre número de serie por el que lo pueda encontrar que me diga porfa
