Resolution

[RichB]

Hi
I have 1 x Dell P190s connected by DVI into Mini Disp
1 Xerox connected byVGA.
Both into 7970 and are fine when i use them for gaming only.
My center screen is Philips 273ELH connected by HDMI used all the time, it appears to be set at its highest setting on AMD Catalyst at 1280 x 1024 and the same in display settings but it doesn't look sharp at all. When it first gets a signal it says "ATTENTION" i should use a different setting but i think its lower, i cant get it to do it now....

Any Help

From what I gathered, your Philips 273ELH is a 1920x1080 LCD monitor, so driving it in anything besides the native resolution will always give a slightly blurry image. Especially if you're using a non-16:9 resolutions fitted to the whole screen, like the 1240x1024. The problem with this is that it will have to stretch the image more on the horizontal axis than on the vertical axis. Which would result in circles being ellipses, and so forth. In other words, the geometry will suffer.

If you in any case want to use a lower resolution for some reason, the best pick clarity-wise (blocky, but not blurry) would be the half-resolutions, in this case 960x540. You could also try the mid-point between 960x540 and 1920x1080, meaning the 1440x810, in which case it would use the scale-factor of 1.5x. But unfortunately, HDMI is apparently quite selective on what resolutions it's willing to input/output, and the 1440x810 doesn't sound like a common resolution. The half-resolution 960x540, on the other hand, might be possible.

Your other option would be to try to output the 1280x1024 (or anything you want, really) with 1:1 pixel mapping, and thus leaving black bars around the actual image. You will have to check whether your Philips supports this. At least Philips HDTVs usually support this. Check for options like “Picture format” or “Aspect ratio”, and select something like “Unscaled”, “Pixel-to-pixel”, etc. The used terms might differ. If there's something like "Zoom" or "Super-Zoom", then you should probably pick anything besides those, as they will usually just mess things up. You'll just have to try and see.

But if you have already tried all this, and it is still a blur, then I don't know what to try next. (Well, there's a GPU driver/software work-around, but it's a bit more tricky... There was a thread discussing it recently, to which I replied.)

Hi
None of those resolutions are listed in AMD catalyst or Display Settings, the highest is 1280x1024.
Also i just noticed it says "Desktop Area" on Catalyst.

If i go to any lower numbers everything just gets bigger and worse...

Are you running the three screens in Eyefinity mode? If so then that requires all the monitors to be the same resolution. If you run them in extended mode then this will allow you to set all the resolutions on each monitor independantly.

I think iv got it.
i have had to remove the other screens rather than disable the display group, this allows me to go higher to 1920x1080, it looks better although when i look at AMD Catalyst it just says under "desktop management - desktop properties" Mode 1080p and desktop area 1080p
