Intel HD 4k, pixel clock limited by Samsung?

I have a problem that i didn't think I would encounter. My last laptop was an Asus ux51vz with Intel HD 4000/Nvidia GT 650m), managed to squeeze out 100hz in 1080p.

Now, with my new Samsung Chronos 7 770z5e (Intel HD 4000/Radeon 8870m) I can't get it to work even though I use the exact same cables and monitor as before. HDMI -> DVI-D adapter -> DVI-D cable -> Acer 120hz capable monitor. What could be wrong here?

I have tried to contact Samsung about it but they have no answers at all... You guys are my last hope. Is there any way to increase the pixel clock if that turns out to be the bottleneck?

I want to try to add a custom resolution using Intel Control Panel's advanced settings, but I dont know what values I should add to get 100hz @ 1080p.

I need values like sync width, active, light time, shutdown time, sync polarity, scanning freq, total. Any suggestions?

Any thoughts in general?

Some more information: Tried every third program like Powerstrip etc to fix this output issue, the second I touch the arrow to change pixel clock the screen goes light blue until I plug out the cable. (Not BSOD, just no picture).

Thank you in advance,

BillSjo

Please provide the model and manufacturer of the TV that you are using.

In addition, could you please post the graphics report generated in Intel(R) Graphics Media Accelerator control panel as explained here:

http://www.intel.com/support/graphics/sb/cs-009476.htm Graphics — Intel� Graphics Driver Report

In addition, copy paste the dxdiag report generated in that system.

Have you tried using a direct HDMI cable connection?

Have you tried loading the latest drivers from Acer for this monitor?

http://us.acer.com/ac/en/US/content/drivers http://us.acer.com/ac/en/US/content/drivers

In addition, check with Samsung for an updated BIOS for the system that you are using.

Yes, I have tried those things. My humble opinion is that my intel hd 4k must be a limited version. Can you confirm that? My last intel hd 4k in an Asus Zenbook could force 100hz in 1080p, this one cant do over 60hz.

It there a way to get by this? How likely is my theory?

Best,

Bill Sjoe

Just to confirm the TV is 120 hz capable, so you are trying to set it to 1080 @ 120 hz or 1080 @ 100hz?

Are you getting the 1080 @120 hz, or the highest it shows is 60 hz?

The monitor is capable of 1080p @ 120hz, used it many times with those settings. My last Asus Zenbook with the HD 4000 could squeeze out 1080p @ 100hz with an adapter from HDMI to DVI-D. When I'm trying the exact same setup now with my Samsung 770z5e it doesn't seem to work.

Im trying to use something like 100-120hz in 1080p, dont rellat matter as long as I can get a bit above 60hz like I'm used to.

Another strange thing, I can push this HD 4000 to 120hz in 1024*768, so I guess this is not a question of a 60hz limit, but a limitet pixel clock in my version.

So, are there any possible limitations that Samsung (or you) could have implemented in my chipset? Is there a way to get past this? Can you imagine any reason why my HD 4000 could do 100hz before but not now?

Could you please attach a screenshot where you see 120hz in 1024*768?

In addition, checking the specifications of the TV and the laptop, both of them should feature a HDMI port, in such case, have you tested using a directly HDMI connection?

Here is me running at 120hz in 1024*768

I have tried HDMI, it doesn't get me further than this HDMI to DVI-D cable im on right now.

I know that my cable can transfer 1080p @ 100hz, so i don't think the problem is with the connection rather than some chipset or driver limitation. Any thoughts?

I created a custom resolution to be able to select this.

Yes, but it won't work for 1080p @ 100hz. I have used the very same monitor and cables for 1080p 100hz for over two years. Then with a Optimus configuration GT 650M/HD 4000.

What do you advice me to do? Any tool/software that might come in handy?

I was trying to check for the provided model number GD245HQ. However it is not on Acer's website. Is it possible the GN245HQ?

Could you please specify if you are running the TV in standard mode, or in 3D mode?
