I got my OTG USB cable today. It works like a charm on Stream 7.
The first thing I tried is to connect my X-Rite i1Display Pro.
Works the same as if plugging device to regular USB.
Ok here's the stuff that'll bring the boys to the yard.
I calibrate the Stream 7 screen and here are the profile for people to use:
1drv.ms/1zINllF add http, I can't post link, This is one drive link)
Stream7_d55_sRGB_native = D55 white point, sRGB gamma (will make your screen yellow)
Stream7_d65_2.2_native = D65 white point, 2.2 gamma (slightly deeper dark gamma)
Stream7_d65_sRGB_native = D65 white point, sRGB gamma (USE THIS, this is Standards for a lot of things)
Stream7_d75_sRGB_native = D75 white point, sRGB gamma (will make you screen bluish white)
*native = native brightness and contrast ratio (calibrated at 50% brightness w/ White LED backlight settings)
Copy the profile(s) you want to C:\Windows\System32\spool\drivers\color
To use it:
1. Search "Color Management"
2. goto Advanced tab > Change system defaults...
3. Then goto advanced > [V] Use Windows display calibration.
4. Click close (the system defaults window).
5. Goto Devices tab, Click Add...
6. Add profile: sRGB IEC61966-2.1 ( this is equivalent to no color management)
7. Add profile: Stream7_d65_sRGB_native (or whichever profile you prefer)
8. Click on the profile you want to use and click "Set as Default Profile"
9. toggle between that and sRGB IEC61966-2.1 to see before n after.
10. Then proceed to sing "My tablet is better than android/ios, damn right it's better than android/ios"
This profile fix 2 issues:
1. Gamma/Contrast issue in HP Stream default profile. (which makes highlight blown and shadow burnt).
2. Calibrate to proper white point and color accuracy.
To my surprise, Stream7 is very close to SP2 gamut coverage and in fact exceed the green gamut of SP2.

For obvious reason, SP2 wins in contrast ratio, gradation completeness, upper white and lower black range coverage.
But for non technical people and NORMAL photo viewing. I'm super impressed by the result of the calibration.
Photos viewed in Stream7 is VERY VERY close to Photo viewed in SP2 (Surface Pro 2).
So there you have it. For people that are skeptical about Stream 7 screen, the answer is DON'T.
Enjoy.
