can set SiS video resolution higher than 1024x768?
in [Asus]
|
From: peter on 8 Aug 2005 14:46 I recently bought a compaq sr1520nx from compusa with a salmon K8S-LA motherboard with SiS 760 chip. The default installation does not allow display resolution any higher than 1024x768. However, if I re-install winXP, then download the SiS 760 driver from microsoft's windows update, then I can set the resolution higher. However, this is not a satisfactory solution, because the microsoft driver is a bare bone driver and does not come with SiS utilities to change gamma, which is something I also want to do. If I download the full set of SiS utilities for this video board from hp, then after installing them I cannot change the resolution to higher than 1024x768 again. Actually, the change resolution slider would let me do it, but the result is a virtual desktop scrollable in a 1024x768 resolution screen. Has anyone figured out how to change resolution to higher than 1024x768 and also be able to set the gamma on this chipset? Virtual desktop is usually a more advance feature than simply changing the screen resolution. Why is this feature available, but not the more straight forward feature of changing resolution to higher than 1024x768? SiS does not provide tech support directly. HP's tech support offered little help, and I have tried everything I can think of. Changing the type of monitor does not help.

Integrated video chipsets usually have a few registers that program the amount of 3D texture memory to steal from main memory, and perhaps also an allocation for the frame buffer. If the BIOS sets the frame buffer allocation too low, and the driver is not clever enough to ignore what the BIOS has done, perhaps that is why you are stuck at 1024x768. On at least one computer here, I had reduced resolutions offered, until I installed a driver for the monitor. I would have thought the computer could talk to the monitor via DDC, and get the supported resolutions, but you never know. Another remote possibility, is that particular driver has a bug in it. But, seeing as it offered you a virtual desktop, that isn't too likely. The memory that the BIOS steals, for the use by the integrated video, is probably not memory that Windows can see or manage. If the memory is allocated before Windows is running, I think you can see how the BIOS could mess about with the successful operation of your video. Have a look in the BIOS screens, and see if there are any params that can be bumped up. A really cheesy BIOS might not show any options, in which case you'll just have to keep testing new drivers. Just some random guesses, Paul

The other solution you posted (replacing a setup.ini file) does work!! (I found that posting via google search but cannot see that in my newsreader OE). I did search asus' web site but did not find that vital piece of article. How did you navigate/found it? |
