I am trying to get this resolution on my ati radeon 9800 pro secondary vga out. I have attached details of my consternation below:
I have a radeon 9800 pro hooked up to the moni on secondary vga out. In my display settings i have the choice of 1280x720 selected but the moni doesn't display the entire resolution. As I move my mouse around, the screen scrolls at the edges to show the whole picture. missing about 4 inches top to bottom and about 14 inches (by eye) side to side. the moni is set to 16x9, refresh is at 60. Anyone know what I am missing? I am running a 3 monitor setup. apple cinema display 23 on radeon dvi out 1920x1200, moni on radeon secondary vga, 21" crt on pci vga card 1024x768. Yes, I admit it, I am a bit nuts with displays. Thx in advance for any pointers,
ATI does this with their drivers. They let you pick resolutions higher than what they think your monitor supports. They then set the actual res lower, but give you a scrolling virtual desktop.
You may be able to fix this by changing the display type. For instance lie and tell the system you have a Sony GDM-W900, then the ATI may pick set the correct res because it thinks your monitor is more flexible.
Also, sometimes you can get that "scrolling mode" if you have the card doing too many things - like if desktop #1 was 2048x1536 (for example), and there wasn't enough VGA card memory left for your 2nd screen to run in full res.
Do a search of the htpc section of this forum and look up virtual desktop.
I don't remember how to fix it, but I believe that is what you have described.
Hello fellow electronics warriors. Lots of whining ahead so you might want to bypass this post if you don't want to hear it!!! An update for those interested or perhaps experiencing my same dilemma. I have tried custom resolutions in Powerstrip, tried custom monitor .inf creation with powerstrip, tried sony gdm-w900 .inf, tried a custom monitor .inf posted by karnis, removed all ati drivers, reinstalled 3.5 ati driver, reinstalled 3.4 driver, tried making moni primary monitor, tried reducing resolution of my primary lcd, all without a positive outcome. started out getting 1280 with virtual desktop, 1024 and lower were fine. then i started getting virtual at 1024 too. now i can't even select 1280 in xp display settings. It starts out being available but when i select it, It says i don't have administrative priviledges to do so, then another screen pops up and says the settings are invalid, then it no longer appears. custom res in powerstrip used to be accepted immedieately. now it tells me to reboot to see if res is accepted. when i reboot custom res is not available so i assume it was not accepted. No wonder things are screwed up after all the troubleshooting i have been attempting. I did manage to get rid of virtual at 1024. (victory, not) After several days of this b.s. i installed my old geforce 2 gts and was able to immediately get 1280x 720 no problemo. Played back the first five minutes of t2 wm9 disc, powered monitor off and took a much needed shower break in preparation for enjoying the movie. when i came back and fired the monitor back up, the monitor is now apparently belly up just when i finally got it to work. no pic and a chirping sound is all i get. I must have killed it, right, running non standard res? So moni wants me to file rma. but the form needs an invoice number. of course with my luck, i haven't received an invoice yet from avscience. called them up, and they can't give me invoice number over phone??? am now waiting for their call back. WTF. And Now i understand that i may not have on site warranty service because i may not be in a non remote area. I have a bad feeling i will be paying another shipping charge to get it back to them just so they can fix it, send it back, so that i still can't use it as intended due to ati driver issues. Anyone else out there as frustrated as me? Thx for letting me vent. also, moni tech support does not acknowledge that this monitor does this res. and ati hasn't responded to my email. I did manage to get 1280 x 756(?) working on an old tnt2 card. gotta love living in this 'wonderful' age of electronics. Oh, and my new 23" cinema display has hundreds of bad pixels. Can't get it replaced cause like a dumbass, I bought it brand new on ebay, but no warranty. European or something, not quite sure. sob, sob, sob, but that's a whole 'nother story. Somebody send me some good luck, i'm in dire need. Thanks,
