monitor not running at native res

TheCenturion · 31 Dec 2008 at 12:30

Until recently, both my monitors were running @ 1280x1024. then I replace one of my monitors with a 19" widescreen tv, but for some reason, it won't run at a res higher than 1360x768, the native res for the widescreen is 1440x900. is there anyway for this monitor to run at 1440x900? I have a geforce 6800 and the latest drivers for my card (178.24).

If it's a TV then thats the res it'll use, iirc only pc monitor use 1440x900, not TV screens

no, it's definitely a 1440x900 tv, it even says it's 16:10 on the box

OK, have you tried forcing the resolution from your display drivers, have you run windows update or installed any drivers for the screen (W/U had an update for my NEC monitor)

there's no way to force it, it won't let me select anything above 1360x768, that's the max res windows is letting me use.

If you haven't already, try:

Control Panel -> Display -> Settings tab -> Advanced -> Monitor and then unchecking 'hide modes this monitor cannot display' then select it from the display settings resolution slider.

tried that, when I selected 1440x900, it wouldn't display and reverted back to 1360x768. Looks like I'm stuck at this res then

are you sure that your card will run than res?

How are you connecting? Most TVs now will need a HDMI or DVI connection to go above the res youre stuck at. I suppose you're connecting by VGA? If so, grab a DVI-HDMI cable and you should be sorted.

thanks, will try and get hold of one, but this monitor is only here as a temporary measure, so I'm not sure. I'm currently connecting with VGA.

Most 19" 1440x900 TVs will do that res over VGA fine afaik - your either going to need to find a monitor def file for that display or use rivatuner to write out the current EDID data and make sure its extended to 1440x900, then load that custom monitor def. Or play around with the custom resolutions option in the nVidia control panel but I've found that to be a bit hit and miss.

My new Toshiba 1080p 37" panel didnt! First things first, before trying to override EDID settings, read the manual for the screen. It should tell you the maximum res for the VGA connection.

See my post above mate. You have the make/model of the panel?

Thats good advice...

we sell a number of 19" TVs at work I've never had any problem driving the 1440x900 ones at their native res off a PC/laptop. Tho anything over 1024x off composite/component generally looks rubbish.

As stated above it's most likely the max res that the display will accept over vga.

TheCenturion · 31 Dec 2008 at 15:03

finally got it to display @ 1440x900, I had to change the refresh rate from 60 to 75 (which is apparently unsupported??) but the only problem is the text has become a teeny weeny bit more difficuly to read

TheCenturion · 31 Dec 2008 at 15:03

the tv is a Linsar L19WDF2V

TheCenturion · 31 Dec 2008 at 15:07

on the box it says 16:10, in the manual it says 16:9?? but on their website it's listed as 1440x900

I find the same with new drivers they are hit or miss with my hdtv at 1360 x 768 some work and some don't work with custom resolution option.
