This is for all that have LG monitors with the latest software that changed UI settings for GAME OPTIMIZER I could not find this anywhere on the internet for an update on what happened to the compatibility modes for DisplayPort/HDMI. Everything is outdated. Apparently LG updated their UI and MOVED the option for compatibility modes to disable DSC. This USED to be in the common GENERAL tab, but NO LG moved it to the External Devices, which makes no sense as it should be with the common general menu. I'm not sure if this is a bug or an oversight, but here it is SETTINGS BUTTON > GENERAL > EXTERNAL DEVICES > INPUT COMPATIBILITY Why would you disable DSC, you ask? Well, if you don't disable this mode, you will not be able to use scaling factors like DSR on NVIDIA. I have seen remarks about AMD being able to use it without this option turned off, but for NVIDIA they are behind on this. This WILL disable high frame rates beyond 144 Hz for the trade-off, but you will be able to scale your resolution higher. link hidden, please login to view TESTED 1.4dsc off (full dsr support higher res) -

The LG internet browser is out of date. I get that error message with many sites. -
After spending two days troubleshooting NVIDIA Surround, I finally isolated the root cause. Hopefully this saves someone else a lot of time. Hardware • MSI RTX 4080 Ventus 3X OC • Windows 11 • 2x LG UltraGear 27GX790A-B (2560x1440 OLED 480 Hz) • Certified DisplayPort 1.4 cables (Cable Matters VESA Certified) • NVIDIA drivers tested: - 576.52 - 610.62 - 610.74 Symptoms NVIDIA Surround would either: • Display "Display connection error" or • Both monitors would lose signal immediately after enabling Surround. Things that DID NOT fix it • Clean driver installation using DDU • Older drivers • Latest drivers • Different DisplayPort ports • HDMI • Lowering resolution to 1920x1080 • Lowering refresh rate to 60 Hz • Lowering color depth to 8-bit • Disabling HDR • Disabling G-SYNC • Adaptive Sync OFF • Adaptive Sync BASIC • Adaptive Sync EXTENDED Root Cause The culprit was the monitor's DisplayPort Compatibility Version. LG OSD General → Input Compatibility Version Default: DisplayPort 1.4 This causes NVIDIA Surround to fail. Changing BOTH monitors to: DisplayPort 1.2 Immediately fixes the issue. After switching to DP 1.2: • NVIDIA Surround works normally. • Available refresh rates become: - 60 Hz - 120 Hz - 144 Hz • 5120×1440 Surround enables successfully. Returning the monitors to DP 1.4 immediately reproduces the failure. This behavior is identical on NVIDIA drivers 576.52 and 610.74. Conclusion This appears to be a compatibility issue between NVIDIA Surround and the LG 27GX790A-B when operating in DisplayPort 1.4 mode (possibly related to DSC and/or the monitor advertising 480 Hz capability). For anyone wanting to use NVIDIA Surround on these monitors: Set BOTH monitors to: General → Input Compatibility Version → DisplayPort 1.2 Then enable Surround. Hopefully NVIDIA and LG can investigate. Additional note: Games with native multi-monitor support should NOT use NVIDIA Surround. Example: DARIUSBURST Chronicle Saviours includes a native Dual Screen launcher and performs better using its built-in dual-screen mode than using NVIDIA Surround. My use case is Rocket League local split-screen. NVIDIA Surround allows each player to occupy a full 2560×1440 monitor instead of sharing a single monitor split down the middle. This workaround makes that possible.

Hi Guys, I share your frustration and I assume there's been no change, still about 13 button presses to change aspect! Surely this should be easy to rectify with the WebOS. My LG is a fantastic TV but for this highly irritating 'design flaw'. I have three old TV's with Aspect buttons on the remote! My partner and I watch a lot of 4:3 TV shows and films, the LG drives us crazy! Come ON LG -

Hi all, hoping for some expert help. TV: LG 65QNED86T6A.ADKFLJD (Russia-market unit, now in Iran), S/W 33.31.68.01 (webOS25), 2024 build. Location settings only show CIS/Russian-speaking countries. Using an original Factory SVC Remocon (WK-17226), both IN START and ADJ (code 0413) lead to the same SVC menu. Current Area Option values: Area Code 3638 / Continent Index 54 / Language&Country CS / HW Settings EU. I've tried entering various Area Option codes (adjacent blocks 3712/3840/3968, and legacy ME/CIS codes from older webOS threads) — all rejected with an error. Continent Index / Language&Country / HW Settings appear to be read-only/derived fields, not directly editable. Has anyone successfully changed the Area Option on a 2024-model webOS25 QNED TV? Any known working codes or is this generation's SVC menu fully locked without RTOOL/GSDF access? link hidden, please login to view -
