Can we disable / turn off the HDMI port to gain FPS??

I was thinking, if the 30fps cap is because of the HDMI port, why not just have a slider that turns it on or off and caps / uncaps the FPS accordingly? Wouldnt that fix the problem? Or is that easier said than done?

Hmmm... Good question!!

Well with the same thought in mind, why not just program the games and/or video out accordingly to use the driver appropriate to the application.

Meaning it should throttle or cut back depending on what you're doing.

There has to be some sort of limitation, either via hardware or software that caused them to set this limit in the first place, it just seems odd.

Why? I get 50 fps on my Novatek with HDMI on so why would you need a switch? I mean you need higher fps than that?

A resolution for increasing the FPS while maintaining HDMI functionality simultaneously has been found. See here:

However a "switch" or app to enable/disable either would have been likely preferred by many on HTC's behalf...

Does the resolution require rooting or hurt anything?? I cant believe something so quickly fixed was imposed by HTC... Does it hide stuttering or something??

of course it requires rooting. the fix works great and improves things a ton.

i keep an eye on things a bit, in the hopes i own an EVO sooner than later.. but i think your wrong:

Important note for HDMI users
It is very likely that this fps fix will disable the use of the HDMI output on your EVO while you use this kernel. Personally I (and many MANY others I'm sure) feel that this is an acceptable tradeoff, particularly since most users will likely never use this feature.

**thats from your link** sounds like it fixes it on your device, but you lose ALL functionality of HDMIout

HDMI works now, they just didn't update that first post to remove that. it was fixed in the past few updates.

guys hdmi works with netarchy's kernel over at xda.

The initial release of the kernel broke hdmi. Then when they dug further into the code they realized they could use keep the hdmi but sacrifice 2-3fps. So that is what they did.

Old = ~55 fps without hdmi
New = ~53 with hdmi

Keep in mind the devs call this their "dirty" hack since it isnt just "lifting" a cap by a simple code edit. This just changed some of the math around so it would work and they are still looking for the bottleneck to completely remove the 30 fps cap.
