23 Up to 15 hours of battery life based on typical Surface device usage. Testing conducted by Microsoft in September 2020 (Surface Pro X with Microsoft SQ® 1 and Surface Pro X with Microsoft SQ® 2) using preproduction software and preproduction configurations of Surface Pro X. Testing consisted of full battery discharge with a mixture of active use and modern standby. The active use portion consists of (1) a web browsing test accessing 8 popular websites over multiple open tabs, (2) a productivity test utilizing Microsoft Word, PowerPoint, Excel and Outlook, and (3) a portion of time with the device in use with idle applications. Wi-Fi was connected to a network. Battery life varies significantly with settings, usage and other factors. 24 Up to 11.5 hours of battery life based on typical Surface device usage. Testing conducted by Microsoft in September 2019 using preproduction software and preproduction 13.5” Intel® Core™ i5, 256GB, 8 GB RAM and 15” AMD Ryzen™ 5 3580U Mobile Processor with Radeon™ Vega 9 Graphics Microsoft Surface® Edition devices.
The USB 3.0 specification was released on 12 November 2008, with its management transferring from USB 3.0 Promoter Group to the USB Implementers Forum (USB-IF), and announced on 17 November 2008 at the SuperSpeed USB Developers Conference. USB 3.0 adds a SuperSpeed transfer mode, with associated backward compatible plugs, receptacles, and cables. SuperSpeed plugs and receptacles are identified with a distinct logo and blue inserts in standard format receptacles. The SuperSpeed bus provides for a transfer mode at a nominal rate of 5.0 Gbit/s, in addition to the three existing transfer modes. Its efficiency is dependent on a number of factors including physical symbol encoding and link level overhead. At a 5 Gbit/s signaling rate with 8b/10b encoding, each byte needs 10 bits to transmit, so the raw throughput is 500 MB/s. When flow control, packet framing and protocol overhead are considered, it is realistic for 400 MB/s (3.2 Gbit/s) or more to transmit to an application. 4-19 Communication is full-duplex in SuperSpeed transfer mode; earlier modes are half-duplex, arbitrated by the host.
On the TV side, make sure you disable your TV's overscan. It might be disabled automatically, but if the edges of your desktop are cutoff, dig deep into your TV's menus for something like "size" or "zoom." If you're gaming, also see if your TV has a game mode. This should help reduce input lag, the delay between you pressing a button and that action showing up on screen. It's also a good idea to lower the sharpness control. I mean, in general this is a good idea, but here specifically it should help you make out fine details better, like text. A TV's sharpness control usually just increases artificial edge enhancement, masking fine details and adding noise. Note the "halo" around the objects in the version on the right. Speaking of text, if you're trying to work from your couch it's likely that despite the extra screen size, text is still too small. If that's the case, you can adjust text size on Windows and Mac.
