Re: Viewing angle dependent flicker

I just tried making a video, it's no use. My phone cam cannot capture the flickering.

Oh well, it's not a showstopper. I've just been wondering if it is normal.

Re: Bug in 64bit Driver on Windows?

Yup, that didn't work out.

Installed 2.10 and the problem persists.

Re: Horizontal scrolling

For a scrolling, or marquee effect, a fixed width font is definitely preferred. Simpler, yes. Preferred, no :P Unfortunately, fixed width fonts waste a lot of precious screen space. It also has a Scroll Screen command which should work well for this application. Exactly what I've been looking for, ...

Re: Viewing angle dependent flicker

Verified on a 5 amps power supply. It's definitely not a power issue :) The flickering is strongest after cold start. As time passes, it weakens. What strikes me is the viewing angle dependency. | = module front <) viewing from left ----> | noticeable flicker ----> | no flicker <) vieweing from righ...

Thanks Troy, that was quick! I will give them a try, although according to release notes for 2.10 the future looks bleak.

Re: Horizontal scrolling

Here's my C# code for horizontal text scrolling for fixed-width fonts (such as default font #1). Enjoy :) if (_ArtistAndTitle.Length > 27) { // increase current start position _artistTitleScrollPosition++; // add spacers to the artist/title string lineText = " " + _ArtistAndTitle + " ...

Horizontal scrolling

I need to implement horizontal scrolling i.e. just a portion of a line of text. Now I could work with string manipulation, but I'm using a proportional font, so a string of a given length (in chars) doesn't always fill the same space on the display (in pixels). I prefer not to use a fixed-width font...

Bug in 64bit Driver on Windows?

I'm developing an embedded device and use the GLK19264 USB Display as an UI. The software is written in C#. When running on Windows (.NET 4.0), this will happen after a brief period of time: - Display stops updating - 9 out of 10 times, the display backlight starts flickering like mad - The virtual ...

Viewing angle dependent flicker

Hi Matrix Orbital,

I noticed on my newly received GLK19264 USB display that, when looking at it standing left from the device, there is quite strong flickering. This flickering disappears if the viewer moves to the right. Is this normal?
