Inspiron 1564-4243 - Maximum Resolution from HDMI Port?

Hi, I hope someone on this board can help. I've been looking for an answer to this for several days now.

I have an (old) Inspiron 1564-4243  i3-330M  laptop, built around 2010, which is used for projecting images at my local camera club. I know the graphics chip is an onboard Intel GMA HD500, but despite my best efforts, I cannot find out what maximum resolution can be obtained from the HDMI port.

I'm looking for 1600x1200, but I strongly suspect the maximum is 1920x1080 -  i.e. TV HD.

The spec sheet for this model seems difficult to obtain, probably because of its age, and what I have doesn't explicitly state the output for this socket.

Can anyone help please?. Thanks.

Check Display Settings to see the max resolution supported. It will be the same for whole computer, not just hdmi.

@Bucko1000, all HDMI outputs support at least 1920x1080, and those also have enough spare bandwidth to be pushed to 1920x1200.  But fyi since even 1920x1080 is more total pixels than 1600x1200, any HDMI output that could do 1920x1080 would also be able to do 1600x1200.  There aren't separate limitations on horizontal vs. vertical pixels.  It's total pixels that matters (along with refresh rate and color depth, but on a 1600x1200 PC display you'd be using the standard 60 Hz and 8-bit color depth.)

@Mary G, that isn't correct.  There can indeed be separate maximum resolutions on different outputs.  A given system might have a VGA output that maxes out at 1920x1200, an HDMI output that maxes out at 2560x1600, and a DisplayPort output that maxes out at 4K.  And there isn't even a "Max resolution supported" item right in Display Settings anyway.  If you click Advanced Display Settings, you will see the desktop and signal resolutions, which will usually but not always be the same, but neither of those is a maximum resolution, and in any case that information is provided on a per-display basis and therefore pertains to what's going on with each connected display.  It is not global to the entire system, nor does that information pertain to the capabilities of the actual output regardless of what kind of display is connected.
