Windows 10: Win10 Won't Output NATIVE 1366x768 To HDTV (Win7 Does) - Fix?

Can't get Windows 10 to output native 1366x768 resolution to HDTV, instead it software scales 1080p down to the lower res which looks horrible -- Windows 7 does not have this problem (i.e. Win display setting 1920x1080 -> TV 1080p, Win display setting 1366x768 -> TV native 1366)

I have a Samsung HDTV which supports both 1080p and a native 1366x768 input mode. When browsing from the couch I prefer 1366x768 @125% DPI, it's easier to read and just plain looks better than 1080p @150% DPI. With Win7 the TV will actually switch its input mode to the native 1366x768 automatically when I change the display resolution in Windows. Not so with Win10, regardless of the display res set in Win10 the GPU always outputs a 1080p signal and the lower resolutions are software scaled down (looks horrible).

So far I have been unable to find a fix for this in Win10. I did come across an article which explained how Win10 changed DPI scaling to accommodate the fact that phones and tablets can turn sideways. The article also pointed to a REG hack to put the scaling back to the way Win8 does it with a program called Windows10_DPI_FIX, unfortunately that didn't solve the problem.

I have two PC's that I've tried, one w/Nvidia GPU and the other w/AMD:
PC1
R9 270X GPU
Asus P8B75-M/CSM MB
i5-3570
16G RAM

PC2
GTX 650 GPU
MSI B75MA-E33 MB
i3-3220
8G RAM

I'm reasonably certain it's a Win10 driver issue. When I upgraded PC2 from Win7 to Win10 the TV was still using its native 1366x768 mode before I manually updated to the latest Nvidia Win10 driver. I've since performed clean Win10 installs on both PC's and the TV will not change input mode like it does w/Win7 -- seems like Win10 always wants to output the display's highest resolution (HDTV 1080p in this case) and software scale the lower 1366x768 res.

Any ideas on how/where to find a fix for this. If I can't fix this I'm going to have to roll back to Win7 *Sad

HDMI Not Working after update

After install of WIN10 my HDMI cable to Samsung HDTV is no longer recognized as 2nd display. Re-installed previous version of Win7 and the cable is recognized and works as before.

Reinstalled WIN10 and again HDMI is not working.

AMD Catalyst Control was updated after WIN 10 new install.

Anyone have a suggestion to enable sharing laptop to HDTV?

Thanks in advance for your help!
