Great For Gaming, Meh For Everything Else.

By Jack

Ok, I Really Want To Love This Monitor And In Many Was I Do. For Gaming This Monitor Is Perfect In Almost Every Way, The Color, The Frames, The Size And Curve. It Provides You An Immersive Experience Like No Other I Have Experienced. The Issue For Me, At Least, Is Expectation Based On Price. When I Am Paying For A Monitor In This Price Range It Needs To Be Good At Everything And There Are Some Detractors Here That I Cannot Get Past Personally. I Will Address Them Below In A Profs And Conks List As The Monitor Is Awesome For Gaming But Only For Gaming In My Opinion. Which With Any Review Is Solely Based On My Opinions, Others May Very Well Feel Differently. Monitors, Like Keyboards Are A Matter Of Personal Preference. Pro’s 800R Curve And 39” Screen Size Make It Perfect For An Immersive Solo Set-up. 240Mhz At 1440p Is Perfect For Gamers. It Lets You Get The Most Out Of 4080 Thru 5090 Graphics Cards. 2K Is Much Better Than 4k For Gaming. Con’s Web OS Is Annoying And Not Suited For A Monitor. Speakers Are Tinie Sounding. Wouldn’t Even Bring This Up Were It Not For The Advertising Claiming Otherwise. As Many Do Not Use The Monitor Speakers, This Is Really A Nonissue. This Is An OLED Monitor And Halo’s Badly Toward To Middle. Video Included. OLEDs Should Not Halo Like A MiniLED Monitor. I Assume This Is Due To The Curve But It May Just Be A Defect In My Monitor. Monitor Is Dim, Noticeably Dim At 270nits. While I Love The Immersive Experience And Frames, I Cannot Let The Halo’ing Go, Combined With The Dim Image Go. This Is A $1300 Monitor. The Text Clarity Should Be Crisp, The Brightness Should Be A Minimum Of 400nits, A Minimum. This Peak Brightness Marketing Garbage Is Just That, Garbage. I Do Love This Monitor For Gaming But It Feels More Like A $400 Monitor That They Tried To Spruce Up With A WebOS. The WebOS Is Also A Detractor For Me. I Have To Navigate Through That Nonsense Just To Use My Computer.

Ditched My Dual Setup for This OLED Beast

[This review was collected as part of a promotion.] I absolutely love this LG 39GX90SA-W monitor! Coming from a messy dual monitor setup, this single ultra-wide display has completely transformed my workspace into something clean and streamlined. The 39-inch curved display is the perfect size with stunning OLED visuals - colors are vibrant, blacks are truly black, and my games look incredible. One of the biggest surprises has been the built-in audio quality. Having speakers built into the monitor solved a major problem for me since I was dreading finding a separate audio solution. Now I don't need to wear headphones all the time, and the sound quality is surprisingly good. This monitor handles everything beautifully whether I'm working, gaming, or watching shows. The webOS smart features mean I can stream content directly without needing my computer. This is an outstanding monitor that delivers on every front - highly recommended!
