Question 1

Will this monitor work with a PS5 or Xbox Series X?

Accepted Answer

Yes, it supports 3440x1440 at 120Hz over HDMI 2.0, but console compatibility can be tricky. The PS5 will output 2560x1440 (not 3440x1440) at up to 120Hz, and you may see black bars on the sides. The Xbox Series X supports native 3440x1440 at 120Hz, but the monitor's HDMI 2.0 ports can run 3440x1440 at 144Hz, so 120Hz works. However, VRR may not work on consoles because the monitor lacks HDMI VRR (only G-Sync/FreeSync over DisplayPort).

Question 2

Is this monitor compatible with both G-Sync and FreeSync at the same time?

Accepted Answer

No, it can't run both simultaneously. You'll choose one based on your GPU. For NVIDIA GPUs, enable G-Sync in the NVIDIA Control Panel. For AMD GPUs, enable FreeSync in the AMD Radeon Software. Both work over DisplayPort. Some users have reported that FreeSync on AMD works without a G-Sync flicker, but it's not officially certified by AMD for FreeSync.

Question 3

How does the LG 34GN850-B compare to the LG 34GN850? Is the B suffix important?

Accepted Answer

The 'B' suffix typically denotes a different region or minor model revision. In this case, the 34GN850-B is the North American version, and it's identical to the 34GN850 (European version) in specs and performance. There is no meaningful difference.

Question 4

Does the 34GN850-B support Picture-in-Picture (PiP) or Picture-by-Picture (PbP)?

Accepted Answer

No, it does not have PiP/PbP functionality. This is a common feature on premium ultrawides but is missing here. If you need to connect multiple sources simultaneously, look at the Dell U3419W or LG 38WN95C-W.

Question 5

What is the response time of the LG 34GN850-B at 144Hz? Is it truly 1ms?

Accepted Answer

The stated 1ms is the GtG (gray-to-gray) response time, which is usually the best-case scenario. In real-world tests, RTINGS measured ~4.9ms average GtG with the 'Faster' overdrive mode, which is still excellent and rare for an IPS panel. At 160Hz overclock, it reduces to around 4.5ms. You won't see significant ghosting in normal gameplay.

Question 6

Can the LG 34GN850-B run at 160Hz natively or only with overclock?

Accepted Answer

It runs at 144Hz out of the box. The 160Hz option is an overclock. To enable it, go to Menu → Gaming → Overclock and set it to 'On'. You'll also need a DisplayPort connection (HDMI 2.0 is limited to 144Hz at 3440x1440). Some units may not reach stable 160Hz, but most do without issues.

Question 7

Does the 34GN850-B have a USB-C port?

Accepted Answer

No, it does not have USB-C/Thunderbolt. It has a DisplayPort 1.4, two HDMI 2.0, a 3.5mm headphone jack, and a USB 3.0 hub with one upstream and two downstream ports. If you need USB-C, consider the LG 34WN80C-B or similar.

Question 8

Can I mount this monitor on an arm without removing the back cover?

Accepted Answer

Yes, the VESA mount is accessible by removing the four screws on the back plastic cover. You can use any standard 100x100mm adapter. The monitor weighs about 6.7 kg (without stand), so get an arm rated for that weight (e.g., a standard gas-spring arm works fine).
