    800x600 stopped working! Help Please! Ex-Audio TS LCD

    Hello. I have a 7" Ex-Audio (Lili rip-off) touchscreen paired with a M10000 board. Up until yesterday, worked fine. I was running at 800x600 at 32bit. Then it went blank...

    Now this wasn't a general blank. It was weird. The buttons (hardware buttons on the monitor), were irresponsive. The only button that worked was the channel selector between AV1, AV2, and PC. The brightness, auto-adjust, volume up/down, and menu buttons did nothing. So I was confused. Anyways, I rebooted. When POSTing, I saw everything just fine. Then when the Windows XP boot screen came... nothing. I can't tell if it froze or what, so reboot. Same thing. Really confused.

    I then decided maybe the resolution was accidentally set to 4 bagillion by 3 bagillion or something and the lcd couldn't handle, so I went into the M10000's BIOS. I switched the settings for the video (resolution and output) for all different things. Even tried changing the memory allocated for video! I tried TV out and connected via an RCA to the monitors AV2 input and success! Fuzzy success, but it was there. I checked the display properties, and it was 800x600. Odd, just where I left it.

    So reboot, changed the BIOS back to regular LCD output at 800x600 resolution, and nada.

    So I thought maybe something software. So I reinstalled XP. I didn't want to lose everything, so I didn't format the drive, I just installed windows into the directory it was in overwriting any bad software/registry settings. Still nothing. Keep in mind that the XP installer screens all showed up just fine. Definately confusing.

    After the reinstall, I hooked it up to an old CRT monitor and the video looked and worked fine at all resolutions. The LCD displayed 640x480, 1024x768, and 1280x"whatever it is".

    The point is (and if you got this far, I applaud you), that the LCD will NOT display 800x600 at any colour depth. Other resolutions are fine but not 800x600! I know it did, because it was for a month or two now. Bewilders me.

    Does anyone know of anyway to fix this. I would send it back for fixin' but I like many others hacked it up. I removed the shiny warranty sticker with haste and dremeled the back casing to finish it with epoxy around the front, Not really an option at this point.

    Anything appreciated.

    How about refresh rate? Did you try changing that?
    Sometime from 72Mhz to 73Mhz did make a different.

    No haven't tried. I never changed it from default to begin with, but I will. You suggest I manually set it to 72Mhz or 73Mhz. Any other possibilities. I usually never mess with frequencies unless videotaping something with a screen in it...

    I tried all refresh rates from 60Hz to 200Hz, and no go. I got nothing for the first few. When it was really high (above 150Hz), the screen was green. Also at 60Hz, it said "out of range" which I thought was odd...

    Anyone else have similar problems or a solution?

    I know this is an old thread, but it's the only one I found which describes my problem, which is the same as the OP.

    My Ex-Audio 7" just decided that it wanted to set itself to 640X480 @ 60Hz and display "out of range" on anything except the windows boot screens (before the real graphics driver is loaded and windows displays in 640X480) even if I try to boot into safe mode, it displays "out of range"

    The LCD has no manual settings that i could fine, only the auto adjust feature which doesn't really do anything in this case.

    Also, since the OSD will only show up when the screen has something to show, I can only even see the OSD in the boot menu/load screen/ other things like that.

    Anyone have any ideas? Advice??

    talk about bringing up a repressed memory!

    here's my solution but you aren't going to like it: change resolutions.

    basically i hooked up a CRT to my carPC, and changed the resolution to 1024x768 and then plugged the ex-audio back in. then make sure you set your frontend to the new settings. for instance i use RR so i changed the ini file to show width and such to 1024x768. also in rrconfig. because the frontend autoscales everything, it looks the same, but it is running at a different resolution . only difference is in windows everything is itty bitty but still readable.

    doesn't bother me too much anymore but in the back of my mind it still haunts me...

    sorry to bear bad news but at least youll get a picture now.

    oh and btw, my typing sucks because im on my phone.

    ^ I totally did that after I posted, while I was just sitting there marinating on it. I thought that it just might be that resolution which is fried. As it turns out, that's exactly right, as you say I changed the resolution on the mac mini by hooking it up to a regular lcd. At 1024x768 60Hz it works fine, though when I'm actually in windows and not a front end, 1024 x 768 is not terribly practical since everything is so small. I'm looking into replacing the ex-audio wih a single DN flipout, as I probably should have done in the first place due o the low posiion of the factory radio slot in my tacoma

    Anyway, thanks for the response, it's just too bad that's this monitor seems to have a propensity to freak out (BTW, I wonder how long 1024x768 will last before it blows out too).

    I've been running it like this since I started this thread really. Seems to be ok.
