Whats the resolution setting for the computer to tv?


Lowest end of the spectrum would be 800x600. More than likely 1024x768 or 1280 x 1024. Could also be a wide screen variant of the above.

2My Mitsubishi WD52725 displays a blue screen suggesting to check my inputs and says signal is invalid..checked all the connections and all is good there..any suggestions? Thanks in advance, Nick


What is your input source and which input cable type? If the source is a PC using a VGA cable, what resolution is the computer sending? 480x640. 800x600, 1024x768, 720x1280 (EIA standard) all at 60Hz are known to work but other modes might not.

If you are using a PC to the HDMI port, it will not work. The only HDMI ports that can connect to a computer will be listed as HDMI/DVI and this TV doesn't have that type of HDMI port.

If you are using any other input source, check try another source or channel. (One of my TVs intermittently finds a digital channel 25-9 and gives that message. We have no clue what station is being found but all the other channels are fine.)

I hope this helps.

Make sure it is set to a low resolution say 800x600 to start with, also ensure you have the "Other" monitor, ie: TV, activated, "Extend the Desktop to this Monitor" and set to Spanned or Mirrored, under "Display Settings". Also turn TV off, then plug it in from laptop, then turn tv on, then start pc. Also ,make sure you have latest drivers for your card.

hi there! first to check here is the HDMI connection, if there are okay then next to check is the desktop properties on PC. From desktop open the Display Properties and go to Settings Tab. On that window you to ensure that you are selecting Multiple Monitors on the display. set the resolution of your display to minimal ratio just to avoid some error such as Mode is not Supported.
Hope this could help.

Desktop resolution


turn power off... turn power on, right after turn on, keep tapping F8 till a boot screen shows up. then select safe mode.
after you boot up into windows, change the setting.
if it won't let you then you need to go into device manager and uninstall the display adapter. then restart computer.
the display adapter should auto install itself to default 800x600 or 1024x768.

Trying to connect laptop to plasma tv model number 42PF9945. keeps displaying picture format not supported. using vga to vga on tv.


Hi,

To my knowledge your Philips 42PF9945 is capable of a maximum of 852 x 480screen resolution at 50Hz. It is TV standard but pretty low for PC work, that being the case, perhaps what is required is for you to lower the Screen Resolution as well as the Screen refresh Rate of the laptop. They may be found in the display properties (Control Panel) or right click on any clear area of your desktop.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
