Controlling screen resolution on web HTML 5 clients
Posted: Mon Jul 07, 2014 5:48 pm
Hi,
When creating a TSplus windows/ java client, there is an option to set or fix screen resolution of the client. With HTML 5 clients, there does not appear to be any way to control the screen resolution of the client or color depth bits of the client. In TSplus version 7.30, the screen resolution appeared fixed and to us, the text was very readable. Although after client is started, resizing the browser window would not change the TSplus client screen and thus some of the client screen would only be accessible by the browsers scroll bars. After upgrading to TS 7.50, resizing the browser window would resize the client screen as well. Which is nice, but bigger problems are occurring. On some computers (those that are capable to show higher resolutions than desired) the initial resolution of the client screen is much higher than the resolution user’s current computer’s screen resolution, thus the fonts on the screen are very small and can be hard to read. Is there anyway to control or set a maximum resolution of the TSPlus HTML 5 client web page? Likewise, the applications that we are using do not need 32bits of color depth. We would like to use the small bandwith of a 16 bit colour depth. Is there anyway to set the HTML 5 client web page color depth? Windows will not let RDP clients change screen resolution or color depth.

OK, through experimentation, I found out that the resolution of the initial screen is kept in two cookies (xdW and xdH) on the client. And wherever the HTML 5 client was opened the initial screen resolution of client portion of the browser is stored. In my case, I have a notebook attached to a monitor with a much higher resolution than the notebook screen. I must have opened the browser for a TSPlus session on the monitor first. Then when I moved the browser to the notebook the RDP session resolution is still set at the monitor resolution and thus the font is very small. Clearing these cookies will allow the client screen resolution to be set at the current screen that the browser is on. However, since this resolution is kept, thus when starting as session on a browser window at a different size, the stored resolution is used. It would be nice to have control of the resolution used, or at least be able to set the expiry dates of the cookies to a day.
Thanks,
Rob.
