Not my time for 480hz

Bought during Presidents Day promo. DEAD ON ARRIVAL. Wanted to do an exchange at the promo price but cant. Called customer support, they told me to reach out to chat, chat told me to reach out to promo team. Im good. Rating experience, not so much for the monitor, well, because it didnt work.

Scam Rebate

I pre-ordered this product within the $200 Virtual Master Gift Card offer window and never received the gift card. I contacted support through live chat and they redirected me to another department. After 38 minutes of holds, I had to send a screenshot verifying that the offer was real, only to be told I would not receive the gift card because I did not have the foresight to also screenshot the Terms & Conditions of the offer which no longer exists. This is a scammy way to get out of their side of the deal.

Incredible monitor but $200 was disappeared

I'm someone who always thinks LG monitors are the best. I bought 27gx790a-b with excitement and again, LG never betrayed my expectations. However, the $200 I was supposed to receive as a promotional event was canceled because I am not currently in the United States. It was a notification that we exchanged e-mails with the person in charge for two weeks, but the ending was canceled unilaterally I've been thinking a lot about this, but just because I'm not in America right now I don't understand that the promotion was canceled

Great looking monitor BUT?

I pre-ordered this monitor when it was advertised to have Displayport 2.1 UHBR20. Not only does this monitor NOT have 80gbps of bandwidth, there was never an update sent out to notify buyers of the change. If I hadn't come across an article about this monitor's port changing I would have been stranded with this monitor. Worst of all I had been EAGERLY awaiting my first OLED monitor for over a year skipping the 240hz WOLEDs, the Dual Mode OLED and the 360hz QD-OLEDs because I wanted to be smart about my purchase and buy an OLED (that if babied) would last several years. I am disappointed to say the least.

Terrible monitor and customer service

Panel quality is terrible, I got a dead pixel about 20 days after getting this monitor. Literal $1000 with a dead pixel in less then 3 weeks. I have 2 other monitors that was less then $200 Ive been using for 8 years and neither of them have any dead pixels. Whats even worse is they refuse to replace the monitor since its out of the 2 week return window.

Amazing

I have had this monitor about two weeks and been using it as much as possible. The display itself is absolutely incredible. The audio out is super convenient. Having 480 fps is a dream. Not having to worry about maxing my frame rate is a beautiful thing. Blacks are pure black and the hdr looks beautiful as well not washed some other units do. So far I truly have nothing to complain about!

It's so smooth

This is a wonderful monitor for gaming. The refresh rate makes the experience first in its class. The colors are fantastic and the 2k resolution is perfect for gaming on the highest settings. I can move the monitor up and down for improved eye lines and I have my usb camera plugged in too.

REWARDS WAS A SCAM

monitor was not the issue , the issue was preordering the monitor and being promised a $200 rewards card only for the monitor to be delivered but the link is nowhere to be found to redeem it. LG that was very very poor and bad timing with everyone involved.

SCAM ON REBATE

Description of the product said you would get a $200 virtual mastercard giftcard if you purchase before 12/25. I purchased it on 12/19! I tried applying the rebate, which says you need the serial number of the product and the rebate was valid till the end on 1/2025. I received the product, i tried looking for the promo link which you cant find it nowhere, i tried calling LG which continuously tried to redirect me to different places which didnt solve the problem. Now they want me to work it out with mastercard, but they dont know anything about the promotion. So is the rebate a scam to make people buy stuff and never get the rebate money?

Finally, the Only Monitor I'll Ever Need for Gamin

As someone who splits their time between competitive gaming and video editing, I've always struggled to find a monitor that excels at both. This is it!

Great features

I'm absolutely excited about the LG 26.5" OLED monitor. The most important for me is the **480Hz refresh rate** coupled with a **0.03ms response time**. As someone who plays fast-paced competitive games, this means ultra-smooth visuals and virtually no motion blur, giving me a significant edge in gameplay. But it also has several other features that make it a perfect fit for my setup as well: The **OLED display** with **DCI-P3 98.5% color gamut** and **VESA DisplayHDR TRUE BLACK 400** is also crucial for my photo and video editing projects. The rich colors and deep blacks ensure that I see every detail accurately, which is essential for producing high-quality content. Moreover, the monitor's **ergonomic adjustments**-including tilt, height, swivel, and pivot-allow me to customize the setup for maximum comfort during long sessions. The **anti-glare, low-reflection** screen is a bonus that reduces eye strain in my brightly lit room. Lastly, the inclusion of both **AMD FreeSync?** and **NVIDIA G-Sync?** technologies ensures compatibility with my current GPU, providing tear-free and stutter-free visuals. The multiple connectivity options like **DisplayPort 2.1** and **HDMI 2.1** make it easy to integrate into my existing system. Overall, this monitor's combination of high-performance specs and thoughtful design features makes it an ideal addition to enhance both my gaming and professional work experience.

Very Excited

In my opinion the most important feature of the GX7 is the combination of the 480hz refresh rate with the DP 2.1 port, allowing for ultra-smooth visuals and the very pinnacle of a gaming experience. This is perfect for me, as I am a massive fan of competitive gaming (particularly Apex Legends) and I have recently got my dad interested as well. If I win this gx7 I will give my dad my old LG monitor and use the GX7 then hopefully when I have saved up enough money I can buy him one too!

480 is insane

I think the most important feature is definitely the refresh rate, I think the refresh rate will really help when it comes to smoother images and better timing on shots in the games I play!
