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.

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.

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.

Official Response by LG - BV

Hey there! We always want you to have the best gaming experience with your LG monitor so you can enjoy all the games you love, like God of War, with excellent picture quality. To use the Displayport 2.1 bandwidth for your monitor, you will need to ensure that the GPU for your PC is also able to support DisplayPort 2.1 to achieve up to 480Hz refresh rate support. So we can make sure everything is taken care of, please send us a private message on social media at @LGUSSupport with your contact details and model number, and we'll be ready to help! *Josh

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!

Official Response by LG - BV

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?

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!
