Green Screen 1920x1080

[Janita Locklin]

Weare having a problem where some of our laptops are having a bit of a weird problem where if you link to our interactive Screen via a USB C docking station it will cause half the screen to turn green this does not happen when directly plugged in, annoyingly it only happens with some laptops not all of them even ones from the exact same batch seem to react differently for one another.

But we have worked out that if we drop the resolution from 2048x1152 60 Hertz to 1920x1080 60 Hertz that everything works fine so we want to force the resolution on this one particular interactive screen to 1920x1080, is there a way to do this via group policy or SCCM for this particular screen?

Some laptops only do it when they are duplicating the screen and some only when they have the screen extended. To say it is annoying would be an understatement, especially when I tested 3 different laptops (same models that are having the problems) when putting the docking stations in and did not get the problem once.

For the life of me, I can't seem to get the right image size for a Zoom background. From what I've read, the recommended pixel size is 1920X1080. My photo app says the image I'm uploading for a background is 1920x1080, but when I set it for my background, I end up with black bars on the right & left sizes which the help files says indicates "wrong size". Any suggestions welcome. I've uploaded the desired background photo in png format (have tried JPG too which behaves the same way) and also a screen grab of what the background looks like with it's black bars. Any/all suggestions appreciated. Platform I'm on is a windows 10 PC, no green screen if that makes any difference. I've got the most recent Zoom client version, too.

The HD setting on the client is really just allowing more video area to be captured by Zoom (fullscreen 4:3 vs widescreen 16:9), but actually sending HD video is dependent on other factors. This means your bandwidth usage for video will be slightly higher, but it doesn't guarantee that you will be sending full 1080 HD, which would have a greater impact on bandwidth usage.

If you wanted to resize the image for fullscreen, you would want to crop that background to a 4:3 ratio. Not sure what exact dimensions that would be, but most image editors have an option to crop at a specific ratio, so it would do the math for you.

User LUT Cube Import

F6 PLUS provides S-log2/3, V-log, Log-C etc, to convert log mode to REC709 for all major cameras. The LUT loading function makes the color calibration work of the previous shooting easier and more intuitive, optimizes the workflow and improves work efficiency. User creative 3D LUT cube or calibration 3D LUT cube can be uploaded to F6 PLUS by SD card.

Brightness Histogram

The Brightness Histogram is a quantitative tool to check the picture brightness.The feature shows the distribution of brightness in an image as graph of brightness along the horizontal axis (Left:Dark, Right:Bright)and a stack of the number of pixels at each level of brightness along the vertical axis.

Peaking Focus Assist

The Peaking Filter is used to aid the camera operator in obtaining the sharpest possible picture. When activated, the internal processor will display a colored highlight on the screen where sharp edges appear. You can switch the peaking color between yellow, red, green, blue, white according to different tone of the subject. The focus level can be adjusted from 1 to 10 levels.

False Colors

The False Color filter is used to aid in the setting of camera exposure. As the camera Iris is adjusted, elements of the image will change color based on the luminance or brightness values. This enables proper exposure to be achieved without the use of costly, complicated external test equipment.

Exposure (zebras)

The Exposure is used to assist in exposure adjustment in the mode of Zebra Pattern. It is considered overexposed and displays the moving warning lines onto the over exposed areas. There is a 1%-100% zebra value that can be adjusted.

Check Field

Check Field is an assistant function to adjust camera color settings. Under the check field mode, you can use red, green, blue or gray pixels to generate the image, because hue and saturation can be adjusted more quickly and accurately in this environment.

Zoom In (100%300%)

Image magnification is HD signal in any part, an amplification for high quality close-up. The touch panel can help you zoom in quickly, zoom out and move the image after zooming in.

Image Flip

Image flip is to flip the image horizontally, vertically, and horizontally/vertically. Simultaneously turning on the horizontally flip and the vertical flip can achieve horizontal/vertical simultaneous flipping.

I suggest to drag the lower right corner of your anchor widget to the bottom right of the visible space, so that your anchor fills the whole screen. Then reset the position and size x/y to 0. Your picture should now fill the whole screen independantly of the actual screen resolution, thus your UI is useable for customers with a screen resolution different from 1920x1080.

Not sure but is the Game/Editor in the Lower Image actually running in Fullscreen? Since I can see the Window-Taskbar I would assume that the Editor/Game is not actually running at 1920*1080 but I could be mistaken.

You guys, i spent over an hour trying to figure this out when finally i was reading official UE4 documentation and a saw something so easy. It is all about your anchor point. You know how you can choose which corner of the screen to be anchored? Well open the anchor menu, scroll down, and there will be stretch option. There is an option to stretch to full screen no matter resolution. Very helpful for fullscreen widgets like loading screens and such. Hope this helps.

I've only had my laptop for 1 week, and until today I'd only used it for programming work. However this evening while looking at some photos I noticed the colors just seemed a bit off. It was really hard to pinpoint exactly what was wrong, but they just looked really really bad, particularly skin tones. It was almost like it had a greenish tinge or something.

To compare I put my old XPS M1530 next to it and displayed the same photos with the same brightness. The difference was quite shocking. Photos on the M1530 were smooth and warn, and natural, and on the XPS 17 they were garish and just plain unpleasant to look at.

Anyway now I'm feeling somewhat devastated, as one of the primary reasons I wanted this laptop, with the fast graphics and cpu etc. was so that I could use it for video and photo editing. However with poor color on this display, that simply is not going to be possible. I'm feeling like now i've bought a very expensive multi-media laptop which will be good for programming and nothing much else. For video and photo work, I'll have to persist with the somwhat underpowered M1530.

Just to provide a little more info. I'm thinking possibly this may be related to the anti-glare coating. When I try displaying a pure white screen, it has a distinct blue-green tinge. Since this happens on a white screen, I don't think it could be an issue with the LCD screen itself, but either with the back-lighting or the coating.

The one notable difference between this laptop and my old XPS M1530 is that it had a TL glossy screen. I'd therefore conclude that most likely the AG coating is at fault. The fact that I can't seem to correct the issue with the control panel, I think kind of backs up this theory.

I have the same problem, intensity of color is blown out and contrast is too high. Really strong blue tint, and it limits any photo-manipulation or other work that I do. Otherwise this system rocks...love it! I've tried to adjust this with the laptop brightness button of course, windows 7 calibration, and nvidia panel, but I cannot get it quite right. This was not an issue with my prior Inspiron 1720 laptop, or any other dell products I've had. I can usually get these settings nailed pretty well, but I can't get this to work since purchase in Apr. 2011. What are we missing? Is it an anti-glare coating? I can't even recall if I got that feature, but I have the documentation tucked away no doubt. Wish I could tame this monitor a bit...

The color temperature of the monitor just appears to be on the cool side, and unfortunately there doesn't appear to be anything that can be done to change this. Desktop monitors, and TV's etc. often have an adjustment for color temperature, unfortunately laptops don't, and there is no way to get the same result by calibrating or adjusting the regular color settings. It may appear to correct the colors at certain levels, but invariably it will mess up other colors. Probably the only way to correct it would be to add some kind of additional warm tone screen protector or something over it. I'm not sure if they make such things though, and it would degrade the clarity of the screen.
