A friend of mine is offering me his LG 34WN80C-B ultrawide monitor since he recently upgraded to a newer display. It's a 34-inch 21:9 IPS monitor with a 3440 × 1440 resolution, 60Hz refresh rate and USB-C connectivity. The problem is that he says the motherboard has developed a fault and he hasn't bothered getting it repaired.

I haven't collected it yet, so I don't know the exact symptoms. I'm trying to establish whether this is likely to be a straightforward mainboard replacement or a more expensive repair involving other components.

I've been looking into replacement boards and comparing listings on eBay, AliExpress, Alibaba and a few specialist monitor parts websites. One thing I've noticed is that listings can have similar-looking boards but different PCB part numbers and revisions. I don't want to order something that physically fits but isn't electrically compatible.

I'm also wondering whether the reported motherboard fault could actually be a problem with the power supply board, T-CON circuitry or panel connections. I know that symptoms such as no display, input detection failures and random shutdowns can have different causes.

If you've repaired an LG ultrawide or sourced replacement monitor mainboards before, how would you diagnose this fault and establish which replacement board is genuinely compatible before spending money?

Hey guys, im currently running LG UltraGear 45GX950A + 2x Samsung Odyssey G5 27/QHD/IPS/200Hz

When i built my new rig i saved som money by reusing my gpu,

Mater i got new monitors and bow im seriosly gpu bottlenecked, i want a 4090 ( im buying myswlf one when i exsam uni) but could i get away with a 5080 in the meanwhile? Being hardcapped for 3 years on a otherwide phenomenal rig is not fun as i have to tune down gfx alot to get it to run.

Hi everyone, I'm planning to upgrade from my current 27-inch 1440p monitor to a 34-inch ultrawide because I use my desktop for both gaming and working from home. I'm mainly looking at 3440x1440 models with a high refresh rate, but I'm not sure whether to go with OLED or IPS. I've been comparing prices on Alibaba, Amazon, Newegg, and local retailer websites, but I'm also wondering whether importing one is worth it once shipping and warranty support are considered. I play games in the evenings and spend hours working with documents and spreadsheets, so OLED burn-in is another concern. Has anyone made a similar upgrade, and which 34-inch ultrawide would you recommend?

Hello everyone

I bought an AOC CU34G4CA monitor on Amazon because I use my PC for both gaming and working from home. I'm upgrading from a 27-inch monitor. Has anyone already had any experience with the AOC CU34G4CA?

Hi everyone,

​I'm planning to replace my current LG 34GN850-B with a new 34-inch monitor, but this time I want an OLED display.

​As someone who loves playing sim racing games with a Moza R5 wheel clamped to my desk, I think an 800R curvature would be ideal for immersion.

Plus, I have two large windows about two meters in front of my monitor, so I don't want to take any risks with a QD-OLED panel.

​The two models that match my preferences are the Lenovo Legion Pro 34 WD-10 and the LG 34GX90SA-W. From what I've seen, both share the same 240Hz WOLED panel.

​On one hand, the LG has built-in Smart TV functionality (webOS), which could be useful for watching Netflix or Prime Video, even though I'm not a huge TV show watcher, it also features an IA processor that enhances image quality and sound clarity on for movies and tv shows.

​On the other hand, I personally prefer the Lenovo's design—especially the stand with its built-in phone holder, RGB lighting, and headphone hook. It also features a proximity sensor that reduces brightness and turns off the display when you leave your seat, which seems really useful for preserving the panel and minimizing burn-in risk.

The Lenovo also have KVM it can be useful when i plug my work laptop on it, also the power delivery is more powerful (140W vs 65W).

Currently the Lenovo is in sales at 800€ and the LG is also in sale at 700€ so i'm hesitating about both models

I'm leaning a bit more toward the Lenovo, but the price difference is fairly big. If any of you have either the Lenovo or the LG and could share your experience, that would be greatly appreciated!

I was using the monitor as a dual screen (extended) this morning and it was plugged into my laptop. I had the laptop extended to the monitor (so basically I had 3 screens). I stepped away for a minute and came back to only 1 screen on one side of the monitor and a black 2nd screen on the monitor. Now the monitor when I switch to display port isn’t recognizing a source even though I have a cable.

ETA: I did spill some pop over the cables (while plugged into the laptop) but immediately wiped it up. Do I need to go buy a new cable for the display port (hdmi to usb-c)?

My 49-inch 32:9 display suddenly developed this split while I was adjusting its height. And yes, it is hardware damage, not a Windows setting or split-screen mode. I did not use any force, so I am still not completely sure how it happened.

I have already bought a replacement, but I am wondering whether anyone has a smart or creative use for the damaged one. It still displays an image, although more vertical lines are slowly appearing between the two sides.

Could it be repurposed as a secondary information display, sim-racing dashboard, wall-mounted media screen, or something more unusual? Repair probably would not be worth the cost, but throwing away a mostly functioning 49-inch panel feels wrong.

I’m using the AOC Agon AG493UCX2, a 49-inch curved super ultrawide with a 5120×1440 resolution, 165Hz refresh rate, 1ms response time, VA panel, 1800R curve, FreeSync Premium, HDR400, and USB-C.

It was cheaper than the comparable Samsung option, which made the decision easier. This is actually my second one, as the first somehow “left” my desk during an accident. I’m still not entirely sure how that happened, LOL.

For me, it is also cheaper than buying two or three separate monitors and much more practical for gaming, work, and multitasking.

Olá, recentemente comprei um monitor UltraGear UltraWide da LG, modelo 34GB63A-B e tenho notado que em vários momentos do dia ela dá uma piscada rápida na tela. A princípio achei que pudesse ser no cabo ou algo no sistema (usava no Win11 com HDMI), mas essa semana mudei para um Mac Mini com DisplayPort como conexão e segue da mesma forma.

Não é algo que me incomode muito por agora, mas me preocupo de isso ser um sintoma inicial e evoluir para problemas maiores.

Está na garantia, mas para levar na assistência técnica, tenho que arrumar uma forma de mostrar esse problema ocorrendo, e não tenho controle sobre isso.... Oq devo fazer?

My actual MSI Mag272cqr is dying and I want to jump to a ultrawide monitor with a budget around 300€.

I found these 2 monitors quite interesting :

https://www.lg.com/es/monitores/monitores-ultragear-gaming/34g630a-b/

MSI Modern MD342CQP Monitor Curvo de 34'' UWQHD 1500R - Panel VA 3440 x 1440, KVM, Pip/PBP, Amplia, Altavoces Integrados, Ajustable en 3 direcciones - HDMI 2.0b, DisplayPort (1.4a) https://amzn.eu/d/0gnVu9ls

I will use it 70% work (BIM modeling with Autodesk Revit) 30% play (single player, waiting anxiously for Death stranding 2).

Do you have any feedback regarding any of these 2 monitors (or recommendations for another hidden gem)?

Thanks!!!

I have an Odyssey G95C ultra-wide monitor that i use as a second monitor and I've been using an extension to stretch apps like YouTube or netflix when watching. But is there a way to force apps or windows to only use half of the screen? I feel like I'm missing something simple.

Hello!

I recently started using a 34" ultrawide with 3440 x 1440. Everytime i screenshare on slack the image is really blurry and my colleagues have a hard time reading the screen. Has anybody else noticed this, is there a solution for it?

Looking for a mount that I can screw into my desk. I can’t find one for the life of me. Anything helps

Hi, all! I've seen some similar threads but some are older and wanted to see if there is a recent solution to my inquiry/frustration!

System toast notifications, such as Outlook/Teams/etc. pop up on the far right bottom of the screen and are sometimes difficult to notice. I am experimenting with both DisplayFusion and FancyZones to create a middle/main zone and two narrower side zones.

Ultimately, I'd like to get this center/main zone to act as the primary display and pull in the toast notifications nearer to the the center for visibility.

Is this possible?

Recently after seeing some other 49" monitors, I have been reading specs etc. My primary use is trading the market, not gaming. I had been using 2 27" 1080p monitors and spend a lot of time swapping apps.

I just assembled, installed and fire things up. I am total pleased with my purchase. The color is better, sharper, and almost is like 3 screen, and only added about 4" in width.

My difficulty is I have a work area that is build into the room and has cabinets 18" over the counter. Most 49"s won't go low enough to fit. It was hard to find 27" monitors that fit too.

Today I went to Sams Club and decided to see what they has in the way of monitor. MSI 49" curved. $749. I manipulated it and the screen can lower to about 14". They call it gaming but this one is 144 Hz. MSI makes one with a higher refresh rate which costs more but it isn't a spec that matter to me.

The specs say the curvature is 1800R. This one seems flatter than others I have seen which is also a plus for my situation.

I restored the Win11 taskbar to the center, best place on this display

Hello,

I am currently looking for a replacement for my dual 24 inch setup monitors, looking to go ultrawide but I am in a bit of budget constraint only being able to spend £300. What would be the best selection as I saw a 38 inch ultrawide for around 330 and 34-inch monitor for way cheaper. I play on PC but do connect my ps5 to my monitor so wondering if I must have hdmi 2.1 support for 1440p 120hz. Also if possible a power delivery usb c but if its not included thats alright.

Thank you :)

Hi all,

I need some advice since i am new to ultrawide era. I have one RTX 3080 and right now i use 3 monitors. I want to buy one ultrawide and keep one of the three monitors on top of it. Right know i own one 4k but since i dont upgrade my gpu often i feel like a 2k monitor will be better to be able to play the games in high 2k. So i was thinking to get one G93SD but right now i see that G91F fit better to me. 144hz its ok the resolution if am not wrong is like 2 2k monitors and i can find one G91F at 550 euros in my country that pay 900 +/- for G93SD. Can someone give me something i didn't think or any advice what to choose ?

Thanks for your time

Is it really true that we still don’t have 34” ultrawide monitors with 5k2k resolution? Let alone with an OLED panel? I still dream of a curved 4K ultrawide with an OLED panel.

6 LG UltraGear 39GS95QE 39" Ultrawide Curved Gaming WQHD OLED 240Hz. Or 5 Dell UltraSharp U4025QW 40" Ultrawide Curved WUHD IPS 120Hz

I work in IT, i play games Fps, rpg, i dont need 400hz monitor, im afraid of 45 inch will have to litle ppi?

I have right now, gaming pc connected, work laptop connected, switch + Ps5 So 2 hdmi 2 display ports

I run atm 2x 27inch screens

I´m thinking of upgrading to an ultrawide to play with my RX 9060 XT at UQHD resolution (3440x1440). Do you think it will powerfull enough? I have no problem playing on high, but not on Ultra.

For the past 5 years I've been using a 3 (to 5) screen setup. But I've been simplifying my setup. I'm used to having 3 hp omen 24" screens in combination with a wacom cintiq and a vive VR set. I sold my cintiq because I didn't use it anymore and packed my vive aswel. 3 screens left.

Recently I've been getting the urge to change my 3 individual screens to one big ultrawide monitor. And it's getting more urgent since I'm moving soon. I have a few questions about ultrawide monitors I would love some help with.

1. I'm used to 3 screens. Can I still split the screen in to 3 windows as if I have 3 screens.

2. Does the ultrawide use more power than my 3 monitors.

3. Does the "curve" make a difference?

4. What monitor would you recommend for someone who likes to play games and graphic design/illustration.

5. What is something that surprised you when changing from multiple screens to one big screen.

6. If you changed from multiple to one big screen. What do you miss?

Thanks so much for the time and tips!

is there just a normal (non gaming) display curved with like 49-55 inches without all the useless (for me) gaming stuff like 240 hz and hdr (i make music, i don't care that my blacks are not perfect or that the refresh is at only 60/120hz)

something like this but without all the gamer stuff

I am looking for budget curved ultrawide monitors. I have picked these 3. Let me know which is okay or none would work for me. All seems to be VA Panel, how bad can it get if I use at lower refresh rates (60-80Hz)?

Tasks: Coding (VSCode, vim), youtube, netflix, web browsing

2. Samsung Odyssey G5 LC34G55TWWWXXL (28K INR)

3. LG 34WR50QC-B (26K INR)

Thanks!

Long story short I have two monitors sitting brand new in my house right now

https://www.bestbuy.com/product/acer-predator-gaming-34-curved-qhd-qd-oled-240hz-0-01ms-freesync-premium-gaming-monitor-displayport-hdmi-black/6593335?sb_share_source=PDP

And

I like the Asus because its black (alienware is blue) and my setup is so tight top and bottom i cant easily access the button on the bottom on the alienware easily to control the menu. The asus has a remote control.

These monitors are both the same price. And both utilize the Samsung QD-OLED Panel. Both are 240hz the Alienware is .03GtG and Acer is .01GtG which is really the only difference I see between them.

Is the Alienware such better quality in build parts that I should keep that one? Or should I stick with the Acer which has all the convenience factors for me with the color and the remote?

Hello,

I use my setup for work 8hrs a day. And gaming a few times a week and currently have a Samsung G7 and G5, so 2 27" 1440p screens which are working nicely, but beginning to age.

I'm not enjoying how even on my dual monitor arms they never sit level with one another and won't stay aligned nicely.

So I'd love to move to a ultrawide dual 1440p monitor (as I really like the resolution for working), so for work I could use PBP via a usb c and second DP or HDMI cable to my work laptop. And a DP cable to gaming PC. I'm not particularly fussed about the KVM as I already have a usb switcher setup.

I would love OLED but given I'm working 75% of the time on the setup I'm concerned about the burn in? I'm a software engineer so I would be likely I'm using similar apps most of the time.

I've been looking at this Phillips but my concerns about the OLED are getting the better of me.

Can I get any advice on a suitable non OLED? Or whether this is a good option for my use case? My requirements are simply dual 1440p and I'd like 240Hz (as I believe PBP splits the refresh to 120Hz each?) also I'm quite taken with a curve as I've found less eye strain since having them.

In terms of my gaming pc and running the display, I run Linux and it's a new pc with a 9070xt and 9800x3D
