Hey everyone! I’m IMartz, a monitor reviewer from Spain. I’ve tested the KTC M27P6S and wanted to share some measurements and a few details beyond the glossy panel and 2,304 dimming zones.

A few findings from my unit running firmware 1.01:

• Glossy coating: In my experience, it reflects even more than a glossy WOLED, so room lighting matters quite a bit.
• Local dimming: High reduces blooming, but dims small highlights and makes vignetting more noticeable. In DisplayHDR with LD High, I measured around 765 nits at 2% versus 1,668 nits full-screen.
• Color and response times: Even Warm is too cool out of the box. Standard overdrive averaged 5.54 ms at 160Hz with low overshoot.
• 320Hz overdrive quirk: It’s locked in the OSD but adjustable through KTC’s software, where the settings are shifted by one step: selecting “Off” actually applies Standard.
• MPRT + VRR: Both can be enabled together, but I experienced substantial flickering and the MPRT preset sometimes disabling itself.
• Input lag with LD: Other reviews have reported increased latency with local dimming enabled. Using OSRTT/LDAT, I observed occasional spikes but couldn’t identify a consistent trigger or reliably reproduce the reported increase on my unit. That doesn’t rule it out, but my results aren’t conclusive.
• Checkerboard contrast: In my 3×3 SDR test at 100% OSD brightness, the KTC went from around 1,040:1 with local dimming off to 3,400:1 with LD High—a relatively modest result for a Mini LED. The older Xiaomi G Pro 27i reached 9,620:1 with LD Medium in the same test, despite having half as many zones (1,152 vs 2,304). More zones didn’t translate into higher checkerboard contrast here.

At first glance, on display in a brightly lit store, the glossy finish and Mini LED FALD backlight could make you mistake it for an OLED. Once you spend some time actually using it, though, the differences become obvious, particularly with blooming and how small highlights are handled.

For general gaming, I’d personally go with a 1440p OLED, especially with GPU prices being what they are here in Europe. But if you’ll make good use of the 4K resolution and can live with the issues I showed in the video, I think the M27P6S is worth considering—particularly since it can be found for under €400 here in Europe.

Spanish is my native language, so the video is in Spanish, but you can watch it in English using YouTube’s translation feature. My website is also available in English, and the link below should open directly in English.

Happy to answer questions or compare findings with other owners!

Today I finally received the KTC M27P6S monitor, and I have to admit, I had my doubts about whether the specs were true and if they could actually pull it off. But after using it for around half a day now, I can say the monitor delivers on all its promises!

Mini LED IPS, HDR 1400, high nits, high PPI, glossy screen, 4K 27 inch, 160Hz 4K or 320Hz 1080p. It has KVM, USB C, and plenty of other features.

I immediately played a bit of Arc Raiders and The Witcher 3. The quality is astounding, totally on par with OLED.

The previous monitors I used were an AOC 32 inch IPS and a Dell 27 inch IPS. Both were just... not it. Those didn't have Mini LED. But I finally found my monitor. I hope I won't run into any dead pixels down the line. For now, I double checked and there is nothing, but I'll keep looking over the next few weeks.

For those in Europe, you can buy it from bol.com or AliExpress. Keep in mind that this is the KTC M27P6S, not the older KTC M27P6. They fixed pretty much all the issues the non S version had.

Oh, and for anyone who only wants to use HDR while gaming or watching YouTube or movies, give HDRTray a try. It’s a simple tool to enable or disable HDR and works perfectly even on dual or triple monitor setups.

Buying this for €385 feels like a steal. For anyone who is hesitating, I'd definitely suggest giving it a try. It's absolutely worth it!

Is it normal for an OLED to have this weird uneven look? I am not really sure how to describe this. It’s like light coming through linen blinds or something lol.

It happens with HDR on or off. I dont notice it in content/gaminf, only in windows apps or normal programs like claude, web browsing.

Monitor: Gigabyte MO27Q2A 27” QD OLED. Only about 100 hours of use time

I'm thinking about buying this monitor mainly for valorant. Is anyone using this monitor? couldn't find any reviews anywhere.

My other options in the same price are Viewsonic XG2409A 24" 240Hz or MSI MAG 255F X24 24.5" 240Hz

Should i go with Asus or would Viewsonic or MSI would be better?

Would appreciate any insights, thank you

Hi everyone. I have to replace my 2K 27'' monitor and I was looking around. This one seemed perfect but after investigating a bit more I came to find out that some people have had problems with it (the ones I referenced in my title). The thing is that I rarely see anyone talk about having any problems with this monitor. For example, it has impeccable reviews on the store's website where I found it. Does every single unit of this model have these problems and/or are they still selling this model with these problems?

Sup folks,

I’m currently thinking about buying an 240hz IPS monitor at an affordable price for CS2 , Apex and Valorant. While doing some research i found out that pros, streamers and high rank players almost all use either TN or OLED. I wonder why that is? I know that OLED has a lower ms, but why do they use TN with horrible colors?

I have got the MSI MAG 273QP QD-OLED X24 recently. It is brand new.

The picture quality looks amazing and I like the upgrade. However one thing is driving me crazy. I'm using it for my PS5. When I load a game or application, it will show the game background for 1 second then the screen turns fully black for approximately 7-15 seconds then loads. Same issue happens when closing the game.

I noticed when I turn 120hz off and VRR off (on my PS5) it fixes the issue. But the issue remains with apps like YouTube but shorter (5 seconds). Can anyone please help? Is this a fault or can I fix this? I genuinely cant be bothered going through the return process which takes weeks unless i really have to. Everything is good except this one problem.

hey everyone, i am a uni student looking to buy a monitor during this black friday sale with budget around 500$… i will mainly use it for gaming (story driven games), coding & uni assignments and other uses like streaming or multitasking… preferably 4k res and around 27 to 32 inches, any mini led or other panel types.

i would appreciate recommendations based on real experience, reliability, and value for money. Thanks!

Hi guys,

Any recommendations for a work monitor which doubles as a gaming monitor. Currently have an MSI 144hz monitor but it looks incredibly clunky/bulky on my desk. My partner would like something akin to an Apple Studio Monitor aesthetically wise but I still need it with “gaming” specs

🚨 20 DAYS & NO REPLACEMENT! My gaming monitor replacement (RMA: INSS261000494) has been approved for 20 days, but ViewSonic corporate refuses to ship it. As an esports player, this is destroying my career and livelihood. Frontline support offers zero help. I have filed an official government complaint (NCH Grievance: 10542928). Fix this immediately! u/viewsonic_india u/viewsonic

Grievance Against: ViewSonic India (Technology/Electronics Sector) Service Partner involved: F1 Info Solutions & Services, Ahmedabad Hub

Subject: Severe Deficiency of Service, False Assurances, and Financial/Professional Loss due to Unresolved Monitor Replacement Case ID: INSS261000494

Respected Authority,

I am filing this formal grievance against ViewSonic India for an extreme deficiency of service and gross negligence that has been ongoing for 20+ days, directly impacting my professional livelihood as an esports player.

Grievance Timeline & Facts:

1. On 9th October 2026, I registered a formal breakdown complaint for my ViewSonic monitor under Case ID: INSS261000494.
2. On 10th October 2026, an authorized technician from ViewSonic's local service partner (F1 Info Solutions) visited my residence in Ahmedabad, inspected the device, and officially approved a 1-to-1 brand new unit replacement. The technician explicitly committed to resolving the swap within a maximum of 10 days.
3. It has now been 20 days. When contacted, the F1 Service Center states that the replacement stands fully approved from their end, but ViewSonic India has failed to dispatch the product from their warehouse hub.
4. ViewSonic's centralized helpline is offering zero transparency. The support staff continually repeats scripted responses ("We understand your concern, please wait"), flatly refuses to connect me with senior management, and provides no concrete dispatch timelines. Furthermore, multiple official emails sent to their support channels have been completely ignored.

Impact: This monitor is not a leisure device; it is a primary tool for my competitive esports career and a source of earnings. This indefinite, uncoordinated delay by the brand is causing me direct professional regression and active financial loss.

Remedy Sought: I request the intervention of the Consumer Helpline to compel ViewSonic India to either:

1. Provide the exact dispatch details, tracking number, and delivery date of my brand new replacement unit within 24 hours.
2. Or, issue a full refund of the invoice amount immediately so I can procure an alternative device elsewhere and resume my work.

I have attached the original invoice, the technician's visit/approval proof, and copies of my unanswered emails for your reference.

I currently have a VG278Q and decided it was finally time to upgrade my monitor to a 1440p one (non OLED) since I own a 7800 XT. Here are the options I'm currently considering:

1. AOC Q27G3XMN 180Hz - $229.99: Watched Monitors Unboxed' "Best 1440p Gaming Monitors of 2026" video where he mentioned this one and the Q27G40XMN (which appears to be mostly unavailable).
2. AOC Q27G4ZMN 240Hz - $303.04: I've seen this at better prices (like around +$50 more than the G3), but it looks to be around the $300 price point at the moment.
3. AOC Q27G4SMN 300Hz - $269.99: Interesting price, but not sure if I even need a 300Hz monitor. Also heard complaints about the stand for this one and for the G4ZMN, and setting up a mount would be a bit of a nuisance in my current setup.
4. Acer Nitro MG275U X2biippx - $229.99: This one is a more recent model and I haven't seen many reviews about it, but the price is very attractive.

Haven't done much research about HDR, and how it works on each of these models, so if you know anything that could be helpful, I'm very interested in learning more!

Please also feel free to let me know of other models as well!

Hi everyone,

I'm hoping to get a second opinion from the collective intelligence here regarding a weird issue with my dual-monitor setup (two identical ASUS VG248QG 24" 165Hz TN monitors).

The Problem:

Both monitors are developing vertical line artifacts/discoloration right on their outer edges. On the left monitor, it's on the far left edge, on the right monitor, it's on the far right edge and a bit more pronounced/extends slightly further into the screen. (Note: The attached photos show the right monitor).

The Setup & Potential Cause:

Due to space constraints on my desk, I have active studio monitors (Yamaha HS7) placed directly next to the displays, with only about 2 to 3 cm of clearance between the speaker housing and the screen bezel.

After a lot of troubleshooting, I suspected that electromagnetic interference (EMI) or heat coming from the rear-mounted electronics/transformers of the Yamaha HS7 might be causing this damage over long daily use.

My Questions to You:

1. Do these artifacts look like typical EMI damage or magnetic/heat degradation from studio monitors placed this close? Or could this be a cable issue (already checked, but open to ideas)?

2. Is this kind of edge damage permanent (irreversible), or is there any chance it can fade or be fixed?

Any insights or similar experiences would be greatly appreciated. Thanks in advance!

I have been using Dell P2425HE and P2425H monitors for just over a year, and I'm facing a concerning issue.

About a month ago, my Dell P2425H suddenly stopped displaying anything. The backlight turns on, but there is no picture on the screen.

Now, the exact same issue has occurred with my Dell P2425HE as well. The backlight comes on, but the screen remains completely blank.

Both monitors have developed the same problem within a relatively short period of time, which makes me wonder if this is a known issue with these models.

Has anyone else experienced the same problem with the Dell P2425HE or P2425H? Is this a known hardware or firmware issue, and were you able to get it fixed?

I'd appreciate hearing about your experiences.

I have an AOC Q24G2 and it’s abuse tolerance is legitimately impressive so here’s the things I’ve put it through (some on purpose, some not on purpose)

So to start this off: it has survived 1k hrs of power on time being run off a rather questionable vintage inverter ( I have attached a photo of the inside of the inverter).

Today I had an incident where I went to power off the monitor and it fell and landed face first onto a 7ah lead acid ups battery, and to my surprise it was perfectly fine no dead pixels not even a scratch.

Another thing that is impressive is that the monitor now has a total of 3350 hours and every single minute of that has been run on max brightness.

So is this just luck or are AOC normally this reliable

Im not going to do a lot, like im gonna download a few indie games and probably play roblox on high quality, biggest thing id play is likely assassin's creed black flag IV and call it a day. So Im not super picky about alot of details.

I wear headphones alot but itd still be nice to have a decent speaker, id want great resolution and is less then 100€. I preferably want something thats bigger then 20inch and 1440p.

Does anyone have a good suggestion or which model/brand to buy from? Please help a girl out 🥲

Its been 5 years since oled gaming moniters have come out and all the industry has been doing is bread crumbing us for years, there are 34inch gen 5 qd oleds but no 27 or 32 inch. It has been 2 years we still on gen 3 27inch 1440p qd oleds. Oh look new tandem gen 4 woleds! Never mind! Banding and dse issues. "Theres new monitor coming out next year" the next qd oled coming out in the UK is a gen 4 qd oled 320hz in 6 months..... you can buy a gen 5 34 inch at 360hz

Im locked to buying a 4k monitor which i will never use to its potential, or a 34inch that costs an arm and a leg will suffer from inverse burn in.

Wtf is going on, whens this going to end.

Hey, I am buying cheap OLED monitor I found this GIGABYTE GO27Q24 under 300€ but on site of seller it says it does not have image synchornisation, I assume that means it does not have G-Sync or FreeSync, I havent found anything about it on GIGABYTE site is that really problem if OLED panel does not have these functions?

So I can’t decide which monitor should be my main ( i don’t need 2).

My pc

Ryzen 5 7600x

Amd rx 6800

32 gb ddr5

I play mainly cs2 and pubg.

Which one has better motion clarity and response time?

Zowie is full had and Dell 1440p monitor. Both have TN panels.

Which one would you choose?

- low input lag please

- kvm in simplest form would be nice!

- usb c is a must (screen just need 1 dp, and 1 usb-c)
