Right now I have managed to get the LP173WF4-SPF1 working with brightness control sliders in windows power and the Clevo control panel but the hotkey FN+F8/F9 do not work. Just need this final piece of the puzzle to have a 100% functional screen. Wonder if Clevo have added this specific panel support to any of their other models?

Hi Prema, can you check the P770zm bios posted here: P770ZM It mentions support for the LP173WF4 IPS panel being added. Is it possible to modify the P377sm-a bios with this code?

Thanks Prema, that worked, same op codes warning as Ethrem reported.

Prema, can I use a newer version of the EC bios 3_07 with the modded np377sm bios? Do I just flash the EC 3_07 bios then reboot etc?

Dang,\guess we are out of luck on getting the only 17.3" IPS panels to work with our Clevos. It was looking so good as well, 100hz and gsync! On the resolutions and refresh rates, it was all working in the bios and pre boot of windows. Only once windows booted up at the logon prompt does it get messed up. Had that fixed but no brightness control is a definite no no unless Clevo adds it in a later EC bios.

Just had a hunch, do the EC bios contain specific code for each approved Clevo LCD something like a whitelist which allows control of brightness etc?

Tried that with lastest 347.52 and the hotkey app you linked, no crashes nut again no brightness control in windows power or the Fn+F8/F9 keys. The hotkey app runs and shows the brightness control but it changes nothing. I also tried using the windows default driver for the graphics card. This enables the Fn+F8/F9 but it doesn't actually change the brightness. Another thing is the default resolutions and refresh rates look messed up for the display making it seem out of phase, lot sof horizontal lines etc. I had to customize my own in nvidia control panel to fix it.

Hi Prema, Can you shed some light as to how the hotkey app works? I replaced the LCD screen with the one from the Acer Nitro/MSI GT72/Lenovo Y70. It's an IPS panel with the ability to overclock 100hz and to have the gsync enabled by the leaked Asus driver. Unfortunately I have lost the ability to run the Hotkey app which will crash and logs an error, the Fn + F8/F9 keys do nothing and the brightness controls have disappeared from the windows power settings. Other hotkeys like mute/volume control/camera etc still work. Application: ControlCenter.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

Is the Clevo hotkey app hardcoded to only work with whitelisted LCD panels? Any possible solution?

I dug a little deeper and it maybe the coil whine from the gpus, never heard such a thing before so not sure if that is it.

HI All, has anyone else experienced strange beeps from their notebooks that doesn't originate from the speakers? It happens most often when the gpus change clocks eg when minimizing to the desktop from playing a game full screen and/or switching back. I'm running gtx980m gpus and haven't heard anything like it from my old gtx680ms so unsure if that is the source of these beeps. If anyone has any suggestions on how to get rid of them I'd be most grateful.

Hi All, IS replacing the heatsink on this notebook the only solution for being thermally limited when overclocking? The max I can run my clocks at on all 4 cores fully loaded is 3.8G. If I apply a 70W power limit then it can run 3.9G with some power throttling. I have already tried applying a dynamic voltage adjustment of -30mV, any more and it can BSOD. Temps are just hard to manage beyond 3.8G and auto fans. I have tried reseating/repasting with GC extreme, IC diamond and Liquid Ultra but it appears the heatsink maybe warped and not making sufficient contact. I am considering ordering 2 more heatsinks since it's a crap shoot whether we get a decent one. I have also looked at buying a new bottom cover and then cutting out the air inlets and replacing with wire mesh for more air inflow. If the worse comes to the worse I will also try lapping a cpu heatsink. Anyone else have any other suggestions for me?

I had similar issues when I tried using Liquid ultra on the cpu heatsink of my np9377sm-a. I believe the cause was there was too much gap between the die and the heatsink. I had to resort to a thicker paste like ic diamond or gc extreme to properly mate the cpu and heatsink.

Any issues with using Clevo gtx980m cards in SLI with this, any special instructions needed? Does this also fix the unequal clocks and voltages with these cards in SLI?

Hi All, does this unlocked bios also unlock the eSATA port multiplier to use several SATA disks at once from the single eSATA port?
