PS4 VSH_4K_Mode Boot Parameter on FAT in Debug Settings

Yesterday I was using the payload from @LightningMods on my 4.55 PS4 Testkit FAT, trying to do some modifications.

So, I go to /system/priv/settings and found some XML files (pictured below).

I open them, trying to do some modification and replaces them. After that, I went to the Debug Settings --> Boot Parameters and saw a new thing that I never seen before.

This is called vsh_4k_mode.

After a reboot it disappear.

So I open up the files and as you can see I saw the vsh_4k_mode on the XML but I still don't know how I enabled it

Also in the ***s document the mode never appear

Same for all theses settings !

Also on my Twitter you'll find a PlayStation File Archive I used for my database at PSX Times.

Can somebody tell me what the benefit is for using this? I have the fat ps4 as well. Thanks

Yeah that's right, pro, fat and slim use same fw packaged in one file. But 4k only active on pro.

4K support is hardware based not software based, it's impossible to enable it on Fat and Slim because they lack the required hardware.

not exactly true. it's no different then looking thro info in dev kit and noticing how even ps3 *** is used. just cause Sony says ps4 has 4K support don't mean fats can't handle it there is very little difference between the models.

 

[Chaos Kid]

there's 2 parts to this stuff software and hardware they work together while to some basis @mschumacher69 is correct. but at the same time no one considered looking at the systems initial files to compare between fat and 4k models and swap using extreme caution.

 

[mschumacher69]

The software part doesn't work if the hardware part doesn't exist...
