please include data here ( pictures, gif etc ) look at gpu frequency both core and v ram thanks for participating

my guess is just to go with a thunderbolt to displayport cable. thunderbolt is able to do 2 k at 160hz and much more.

currently need to post an answer to make my topic visible again thanks for understanding as the topic was moved by a mod to "user review" and have been moved back

hello to every tech lover out here ! i'm a quiet and peacefull web designer/ video editor in France. i say that because today is the day that i stop being quiet and patient, because as much as i am, i have limits. never buy the surface book line ( 2nd generation ) if you plan of doing graphics intensive work. the fact is that, as bizarre as it can be… the gpu goes insane when connected to an external monitor via usb c to displayport, and lose so much perfs that it can't even get past a gtx 960m performance and goes lower than that ! i went and tested in details 3 surface book 15 and collected the results of a current YouTube friend "OWNORDISOWN" to have a larger idea of what the f*** is going on !, results are very bad... Microsoft services in France are the worst you can get , they take you for a marble and solve Nothing, they just know how to reinstall drivers, look at the task manager (even when you say that there is no task/processing errors or shady .exe running and wrecking performances ) look if you have any update then say "your unit must be defective" ….. and that's not the worst part ! i went to contact them because i knew the surface line have a problem, but can you Believe it ? they can giggle at you went you tell them you tested on a pethora of devices and have results from all over the world see the link bellow https://answers.microsoft.com/en-us/surface/forum/surfbook2-surfdrivers/surface-book-2-15-1t-connect-to-monitor-for-gaming/b6119f0c-d4a2-4169-8c3e-68845f7709ff In a first time, i would like some feedback : some of you guys that own a surface book 15" or 13" please do this test if you have time and passion to spare : plug a displayport monitor to the usb c of the surface, select the external display as master display, kick the surface in max perfs and run any type of game you want or really intensive gpu sofware for 10 min or more and post the results here ! Be sure the gpu is giving it its best by setting the nvidia control pannel for the app you will be running into " prefer max performances" you can run afterburner or any other gpu setting fiddler you have, and look at the frequencies of both Vram and core clock….take screen shots, videos, GIF, anything that show the result of the test so we can look deeper into this sh** to take a firt look here's mine (see pictures i linked) any comment is good as long as it doesn't state anything bellow: - changing device once again - install drivers for GTX - change app - change cable - use an other PSU or disabling performance mode (i tryed and the gpu went to 94°c) because of the fan curve being slow as heck ( hello mac settings in a window machine ) - OMG UR GPU MUST BE OVERHEATING WDFBBQ, nope my gpu stand as a max of 78 °c when the card is pushing its full boost ( core at 1.8 ghz and vram at 4 ghz ) - trying to lock the frequencies via afterburner or other sofware ( tried that and it doesn't work ) have fun and a very large thank you at everyone who will take part in testing this. ps ( i know the pictures doesn't show the gpu load, because it took thos photos for "Microsoft service France" to show them it wasn't a overheating issue, but the load is at 100 % all the time)
