A poll - your monitor resolution

I created a vga driver which displays the picture @ 1920x1200 resolution - maybe it is simply too high to be used.

So there is a poll. What resolution is your monitor capable of.
Maybe there should be a switch/a register which will allow a resolution change.select.

    To all moderators: change the "fimest" with "finest" if it is possible.. :( And it should be 1680x1050.

    I answered 1920x1200 because that is my highest resolution monitor but I most often use a laptop that is limited to 1680x1050.

    As I see the most of monitors are 1920x1080. So it should be a switch/register/sth which can make my driver work with this resolution. The pixel clock is 148 MHz, the difference between this and 154 MHz 1920x1200 clock is about 3%, so when I only change timings, 1920x1080 monitors should display this.

    The vertical resolution will be then reduced from 1120 to 1000 pixels. All as in good old times... PAL vs NTSC version... 525 vs 625 display lines... and now there will be 1200 vs 1080 lines.

    For my monitor on mega workstation, I have one of those 4k 27" monsters. Its really great and only cost a couple hundred bucks, cheaper than some 1920 offering.
    For my prop projects, I use character only in al cases so far.
    Aside from the JupiterACE project NONE of my prop project have needed to generate video at all.
    All other instances have used character only on a terminal program on some other device. On PC, teraterm (windows) or minicom and picocom on linux.
    All non PC instances (i.e mobile) have used bluetooth + android device as terminal interface. Either the galaxy phone or the Nexus tablet, which ever is closest at hand.

    Since the display device itself can handle any picture of any format, image support in the prop driver seem unnecessary.

    Of course, this is likely the exception case, but may be of interest anyway.

    I added a demo @ 1920x1080 to the retromachine topic.
    The 1920x1080 timings are still non-standard - if someone has DE2-115 and 1920x1080 monitor.. please check if this demo can run in your environment. I don't know how exact these timings have to be - I can see now a picture on 1920x1080 monitor and it tells this is 1920x1080x60 Hz, so all seems to be good... but then, these timings are far from VESA standard and they have to be until I change the retromachine verilog code to get rid of some hardcoded constants which are still there.

    I have three monitors on my main machine (Mac Pro). One is 1920x1200 and the other two are 1920x1080.

    However the monitor I have for my electronics projects is only 1920x1080. I would suspect most people like me have quite a low res display for that sort of purpose.

    My main monitor is 3840x2160, and my secondary monitor is 2560x1440.

    That sounds like a nice setup. What is your main monitor?

    In all honesty, I don't have a clue what my monitor resolutions are.

    I have three VGA monitors and two notebook computers -- all different. And now I have a new Asus ZenPhone with whatever it has.

    You may think this odd, but for most of what I am doing I don't try to get the highest resolution out of my monitors. I simply want to learn how the code works and verify that it does work.

    When you start working toward getting the utmost out of you monitor, you have different issues and more issues to contend with. So I just Keep It Simple and strongly suggest that new learners start out with learning the code first at a reasonable resolution.

    Just look at that nasty HDMI cable and you will begin to realize that as you desire more, you are going to have to deal with electrical issues as well as code issues. (I have one HDMI capable monitor that I am happily using in VGA mode.)

    On the other hand,
    if I were to get into computer animation and graphic creation, I would get a 44" HDMI TV to use as a display.

    The main monitor is a Dell UP2414Q Ultrasharp. The secondary older monitor is a Dell U2713H Ultrasharp. Both have 30bit color and reasonable response times.

    I have these because most of what I do is coding, with a little reading of technical docs and datasheets. I want to have as much text/code visible without scrolling as possible, but I also want it to be well defined and readable.
