The Ethernet port on the LG CX 65 inch Class 4K Smart OLED TV w/ AI ThinQ® (64.5'' Diag), Model # OLED65CXPUA has a speed of 100Mbps. If you are only getting 50Mbps, check the type of ethernet cable you are using and the length of the cable you are using, and check to see what speed your router supports. Using Cat-5 cable will technically give you 1,000 Mbps while using Cat-6a cable will technically give you 10 Gbps, but that's not going to be of much use if you're accessing an internet connection that gives you a maximum of 100 Mbps. The TV does not require any more than 100Mbps. Unlike a PC, there is no multi-tasking on a TV. Wi-Fi on the other hand, has been keeping pace with the average internet connection. The Wi-Fi 802.11n standard will give you up to 150 Mpbs, while the 802.11ac standard will give you speeds up to 866.7 Mbps. The Wi-Fi module in this TV is an IEEE 802.11a/b/g/n/ac module. HD video (720p or 1080p) streams require a bandwidth of at least 5 Mbps, while the best internet speed for 4K streaming is a minimum of 25 Mbps...^IFV

Whether or not you should buy the LG CX 48 inch Class 4K Smart OLED TV w/ AI ThinQ® (48.2'' Diag), Model # OLED48CXPUB to use as a computer monitor for doing all kinds of drawings on AutoCAD is at your discretion and will depend on how long to use it for that purpose. Burn-in and image retention are possible on virtually any display. However, with an LG OLED TV, any risk of burn-in or image retention have been addressed through the use of technology that not only helps protect against damage to the screen, but features self-healing properties so that any short-term image retention that may occur is quickly rectified. It is rare for an average TV consumer to create an environment that could result in burn-in. Most cases of burn-in in televisions is a result of static images or on-screen elements displaying on the screen uninterrupted for many hours or days at a time – with brightness typically at peak levels. So, it is possible to create image retention in almost any display if one really tries hard enough. And even if image retention does occur from extreme usage, it can usually be mitigated within a short period of time by turning the display off for a while, and watching a few hours of varying content (such as your standard TV watching and channel-surfing). Additionally, LG OLED TVs come with special features and settings to preserve image quality and prevent burn-in and image retention. First, there is the Pixel Refresher feature n the OLED Screen Saver feature that calibrates any issues that may arise on the screen when your TV has been turned on for a long time. Calibration takes more than an hour. The second feature that can be employed is the Screen Shift feature which, moves the screen slightly at regular intervals to preserve image quality. A third option is the Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention. So, in short: Reasonable, responsible usage of an OLED TV, combined with powerful image preservation abilities should result in a seamless home entertainment experience. Your drawings on AutoCAD are static images that could present issues as described above, especially if they are displayed on the screen uninterrupted for many hours or days at a time with brightness typically at peak levels...^IFV
