Chart not being updated on laptop while display turned off or lid closed

All 3 of my charts in market replay stopped at some point with the display turned off since the replay takes 6.5 hours.

It happens at random times. This started around November 2016 release.
Everything is still calculating in NT8.0.3.1, the strategies are running fine, it's just all the chart stops updating. Before I noticed on my Win10 laptop, and now it is on my Win7 laptops. 2 of them specifically today. (It didn't happen on last nights run).
If I touch in the chart with the mouse and move the candles, it will update to the most current day.
Surprisingly - I just uploaded the screencast image, and looked at my laptop screen - and all charts finally updates to the current date.
My other laptops still has 2 charts that haven't updated yet (I did manually force the ^VIX chart to update).
I'm not too concerned about it - all the results are there and everything else is as it should be - but this might offer some clue into live with charts stopping and not updating.

Originally posted by aslane View PostSounds a lot like a problem I reported in the Beta (and it still persists in 8.0.3). See http://ninjatrader.com/support/forum...ad.php?t=90367
The problem is NT does not update/render a window if there is no update (no new data), but the issue is with WPF/Windows/Graphics drivers when the display is turned off the cache of the window contents is lost, and when the display is turned back on the window is rendered black by the OS/driver. This may be graphics adapter specific, but I know it happens when using built in Intel GPU (which would cover some laptops also).
I provided a potential fix for NT in the original thread but was never implemented. NT needs to detect that the display turned on and mark all windows to update/render.
I've been having issues with my other laptop running NT8B4 so I haven't paid attention as much - but I do know it is running NT8 with the Nvidia Quadro, as the power button is Orange. I do not recall this kind of chart stoppage on there.
Interesting, my newer laptop I can not change from balanced. I'll have to try on reboot next time. Will report back to see if it helps this week.

Originally posted by sledge View PostGood tip about the laptop Intel GPU. My Windows 7 box is running NT8 with display off (on 2nd monitor, so not sure how this plays into things), but the light on the power button is still white (indicating no Nvidia Quadro activity). I changed the Intel performance setting from Balanced to "Maximum Performance".

I have a ^VIX chart stuck at 1:30pm. Going to restart with Nvidia Quadro 2000.

Using Nvidia Quadro secondary addon card did not help previously.
I have upgraded to 8.0.5.0 tonight and have 1 laptop running with Intel HD and the other laptop running with Nvidia Quadro (both on latest drivers).
I will be keeping my eye out on this one.

Screen is off. Using remote desktop connection to access, so screen doesn't turn on.
Will keep watching.
