I have a laptop computer with integrated Core i5 Intel HD graphics..

I want to use the vga output to connect to an old tech CRT tv that has an RGB input port, So I'm using a vga to RGB cable. I heard that the cable will not work until I set the output of the vga port to that compatible with the TV i.e the resolutions and refresh rate..

on opening the custom resolution section of the Intel HD graphics I get a scary warning about possible damages on using custom resolutions etc.. but no proper mention of what conditions will actually cause the damage.

so if i decrease the resolution and refesh rate to say PAL standards will that hamper the hardware??

Is that this message ?

"Altering resolutions may (i) reduce system stability and useful life of the system and chip-set; (ii) cause the chip-set and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat and other damage; and (v) affect system data integrity"

Answer:

No, it won't do any harm.

In the past there was some discussion that using a higher refresh-rate / resolution could damage your CRT monitor (the only ones that were used that time). And although it would be possible, nobody showed a monitor who got damaged by those frequencies.

And using smaller resolution won't damage your monitor, nor your Intel graphic chipset.

Edit: if it's that the message taht appears when you change resolutionm, it's (almost) the same message that appears in Intel manuals about tuning:

And those warnings are about problems that might appear when people try to overclock their systems, i. e., using it in frequencies higher than the original ones. It's a simple warning that will eliminate resposability from Intel in case something bad happens.

Using a lower frequency / resolution could only make your chipset work slower.
