HDR

[Tapi]

I have tried to set it ON (ULTRA settings) but the result seems to me not only lighter but also more "flat", i.e. not only light colors are lighter but dark colors are lighter too.

HDR stands for High Dynamic Range so I thought there should be a more noticeable difference between bright and dark colors.... 

I am using TN LCD (QHD resolution, G-Sync, 144 Hz) so I thought it is a TN technology that is the cause why HDR seems to me so bright and "flat".

So I scanned YouTube for some vids and found this one: https://www.youtube.com/watch?v=L_5aUSGXwPM

Authors result is visually similar to mine.

Do I miss something about HDR?

Well, I found out this piece of info but not sure if it is relevant:

The latest Windows 10 versions for instance will support HDR, but from many systems you will see some odd behaviour from your monitor when it is connected. The image can look dull and washed out as a result of the OS forcing HDR on for everything. HDR content should work fine (if you can achieve it - more in a moment!) and provide a lovely experience with the high dynamic range and rich colours as intended. However normal every day use looks wrong with the HDR option turned on. Windows imposes a brightness limit of 100 cd/m² on the screen so that bright content like a Word Document or Excel file doesn't blind you with the full 1000 cd/m² capability of the backlight. That has a direct impact on how the eye perceives the colours, reducing how vivid and rich they would normally look. It also attempts to map the common sRGB content to the wider gamut colour space of the screen causing some further issues. Sadly Windows struggles at the moment of turning HDR on/off when it detects HDR content, so for now it's probably a case of needing to toggle the option in the settings section (settings > display > HDR and Advanced Color > off/on).

It's possible that the "black" in the non-HDR picture is the result of truncation due to lower frame-buffer depth and image compression.

Just looked at it at much higher monitor brightness - it is not totally black.

If it is the same as in photography, then the idea is that lighting will be more balanced between indoor scenes and outdoor scenes in the one shot.  What this means is that if you are taking a shot inside a room with a window, no longer will it be either you get the lighting right for the inside of the room or, you get the lighting right for the scenery shown in the window.  This means either the Window scenery is too bright and blown out with its lighting range or the room itself becomes too dark so as to allow for the higher light range of the outside light as shown in the window.

 

Our eyes can deal with both cause we are special and have that ability but in Photography it usually means you have to take multiple instances of the one pic with different F-Stop (Aperture) settings and then build the image to represent what we see naturally.  Modern digital cameras with their sensors and built in software can now do this automatically. 

 

If you look at the split screen image of HDR off and HDR on, you will not that with it off, the inside cockpit shadows drown out the detail of the cockpit.  With HDR on, you will still see the area in shadow but, it will not drown out the detail under shadow whilst still being able to make out lighting detail outside of the cockpit.  Notice more the difference under the panel where the rudder pedals are.  There is more detail which can be seen in HDR that is too dark in the non HDR split.  It is still under shadow but you see detail and form as you would in real life.

HDR ON

 

HDR OFF

 

Notice how some details completely disappear in the shadows without HDR (fastener in top left, instrument panel).

Be careful to not confuse HDR rendering with actual 10-bit HDR video (requiring special hardware).

OK, you are right.

But comparing both screens - subjectively HDR OFF produce a better image for me. HDR ON seems to me too much bright (especially snow and sky). Maybe if I have IPS panel I would see it differently and HDR ON would look better then...

 

Thanks all for answers. I think I now understand why HDR. It is clever technology but it needs quality LCD technology as well. I think it is limit of TN technology of my LCD that makes the final HDR result too much bright for my taste...

You could also try adjusting the gamma/contrast/brightness to get an image that appeals to you with HDR enabled.

Would You mind taking a shot of a plane against a forest in Kuban map with and without HDR? I have OLED panel and I seem to lose my target instantly when practicing bnz attacks?

Unfortunately, I'm away from my computer, so I can't produce any new screenshots now. However, I've heard that quite a few people have trouble spotting targets from above. Not sure what effect (if any) HDR has.

Brightness: 0% but still too bright image due TN technology so this setting doesn't help

Contrast: 50% ideal setting but do not solve the problem

Gama: THIS SETTING HELPS A LOT WITH HDR ON - I set in game gamma to 0.8 and LCD's gamma to middle value 2.0 (OSD offer three settings 1,8 and 2.0 and 2.5) and I am now satisfied with HDR ON 

 

Thanks for tips!

Has nothing to do with TN technology. What I did on my TN Monitor was this

 

Changes in Graphic Driver

Gamma = 1,5

Brightness = -100

Contrast = 138

Saturation = 200

 

-> after this was done I made some very small changes in the Settings from my Monitor.

 

This Game doesn't support HDR - This is not HDR what we see when we enable HDR in the Game! The name "HDR" what this Game use is very misleading.

-> To see and to enable HDR in Games you need a "HDR Ready Monitor" that support the new Vesa Standard DisplayHDR 400, 600 or 1000

Thx, changes in Graphic drives offers wider range of settings then OSD menu & in-game gamma seetings. 

Combination of all three methods gives me the very good result and HDR ON is great even on TN LCD.
