My Radeon card isn't recognizing the monitor and Catalyst won't read its full resolution (1024 x 768).


Hello there
The HD 2400 is a pretty old card and I doubt it will give brilliant graphics.or will it run DX11
However.
1)Have you disabled the 'on-board' graphics in your BIOS settings ? Your computer will not recognise it if the old on board chip is enabled.
2) Have you tried connecting the 2400 using the 15 pin video connector ?
3) You say it isnt 'recognising' the hd2400 and yet you are saying the monitor is working at 640 !!!! Which is it. Does the monitor work on the old onboard output or the HD2400 ?
4) The version of catalyst depends on your operating system and whether 32 or 64 bit.
Use the right one via here http://support.amd.com/en-us/download
and uninstall the old one first..
5) If the monitor does not work at all on the HD2400 try the card in a different PCI slot.
6) ALWAYS check after you start the PC that in 'Device Manager' that the display adapter (hd2400) is recognised.
7) run ' DXDIAG ' to see how good the monitor is. (type in dxdiag the start orb search box)

Change the resolution on my Samsung B2030 LCD Monitor


1600X900 is a higher resolution than that of 1280X1024. Therefore 1600X900 is a better resolution. If you would like to run at the lower resolution simply right click your desktop screen and click properties. Then on the settings tab use the slider bar to adjust the resolution. Lower to the left and higher to the right. If the desired resolution is unavailable then you could try downloading and installing the latest drivers for your graphics card installed in your computer.

Your card will either be AMD/ATI Radeon or Nvidia. You will need the model number of the graphics card, the latest drivers may increase resolution support for your card.

Also look on the bottom right hand side of your screen for an Nvidia Control Panel logo in green. Right click it and select the option to "change screen resolution" This may provide you with additional resolution options.

Take care!

How can i change the preset resolution of my gnr ts900 monitor.the resolution is set to640x480. this is insufficient for my new radeon hd5450 graphics card.


The video resolution setting is done AT THE MONITOR DISPLAY PROPERTIE SETUP, not at the monitor. The video card driver is up to date?
What OS are you running?
If you are running Windows 7, you need to find driver for this model.

Unable to connect my pc to TV


The reason why your TV is showing no input from your laptop is because of the display resolution of your graphics card, which is higher than what the TV can handle.
What you can try is, when your system is powered up, just go to your display settings, then reduce the systems display resolution to--preferably 800x600, then go to where you normally select the output, and select 'Output to external monitor"...this should send the signal input to the monitor.
Most Laptop graphics display resolution are generally very powerful as compared to what the TVs can handle.
I have actually dealt with a no input signal like this before, and this was what I did.
Hope this helps.
Goodluck!

Cant utilize extended monitor function in XP w/ onboard chipset as other VGA out


You cannot use both the onboard video and a separate card at the same time. Are you trying to use multiple monitors? Your video card must support that if you are, and the Radeon 7500 does not mention that it does. If it does, the ATI Catalyst drivers will have the option.

Can't display 1440x900?


I have a different LCD TV and video card, but I have the same issue.

To work around it, I have to toggle to make it the primary output. It will not work if set to extended, or set to both screens.

Your screen refresh rate may be too high for the monitor or one of the parts might be incompatible with windows try lowering your screen refresh rate. Or checking windows for a compatible driver for the chip or monitor.
