Samsung 4K - can't run FSX in full screen

[simflyer11 0]

Hi

 

I purchased the Samsung 4K UHD TV and connected it to the HDMI output on my GTX 770 3840x2160)  to the TV's HDMI input using an HDMI-HDMI cable.

 

FSX runs fine in windowed mode, with lots of vertical screen tearing.

 

In full-screen, the screen repeatedly flickers between full black and the desktop.

 

How can I fix the vertical tearing in windowed mode, and get full-screen to work?

 

I have FPS locked at 30 (also tried 20),  nvidia inspector has Adaptive Vsync on, and Vsync forced on (also tried "Enable the 3D application setting" and "1/2 refresh rate".)

 

I previously used an LG 23" LCD at 1920x1080 with zero tearing in full screen mode.

 

Thanks for reading.

Do not like the sound of that... I have been looking at that screen as a possible upgrade..

I have a regular Samsung HD TV I'm using and, for whatever reason, my sim crashes when I go to full screen.  I always figured it was a setting or something in my sim.  Never thought to think about the monitor.  It's never mattered much to me since I prefer windowed mode but, still, it's not a good thing.

Make sure you're using a Cat II (aka "high speed") HDMI cable.  Some of the cables designed for older specs (pre HDMI 1.4)--especially long ones over 5m in length--aren't going to be able to reliably carry full HDMI 1.4 (i.e. 2160p30) bandwidth.  I suspect cable issues are *really* going to rear their heads when HDMI 2.0 starts coming into vogue for people wanting 4K@60Hz.

 

For tearing issues in windowed mode, check out this old thread:  http://forum.avsim.net/topic/375526-addendum-to-vsync-fix-windowed-mode/
