DisplayPort (DP) cables do not technically have version numbers like 1.4 or 2.1; rather, they are classified by bandwidth capacity (e.g., RBR, HBR, HBR2, HBR3, DP40, DP80). Version numbers are marketing labels, while certified cables ensure performance for features like high resolution (4K/8K) and refresh rates. While many retailers label cables as "DisplayPort 1.4 cables," VESA does not officially classify them this way; any cable, regardless of "version" labeling, will work if it has sufficient bandwidth. Higher-rated cables (like HBR3) are generally backwards compatible with older devices, allowing them to function properly across different standards. The DisplayPort on the LG 27-inch UltraGear™ IPS QHD 1440p 200Hz 1ms Gaming Monitor, Model # 27G610A-B, is a DisplayPort Version 1.4 port, and the monitor has a native QHD (2560 x 1440) resolution, so the included DisplayPort cable will be a DP40/HBR3 cable, which supports up to 4K@120Hz or 8K@30Hz...^Ivan.
