Is it possible to upgrade FHD panel with QHD? As I saw in previosly related topics some members discussed that you need to replace lcd panel connection cable?
May be someone already has experience with it?
There's two mainboards - easy explanation is one supports GSync, the other does not. The good news is you can use any of the 4 panels in any 17r4, but you'll lose GSync if the panel doesn't support it, and you won't gain GSync if the panel supports it but your motherboard doesn't....
Personally, I don't care and am OK with the panel running in refresh mode instead of GSync - I care more about resolution and panel quality. I've decided not to install a 4k panel, but patiently waiting for a decent priced 2k panel.
This is an upgrade that we don't recommend since it is not a simple procedure and we can't guarantee functionality. You'll need to replace not only the LCD, but the entire assembly (LCD back cover, bezel, cable, etc).
Yes, of course, this is not easy. But I have read that there is only one difference in the connection cable. According to this thread, you'll need to change the 40pin cable and matching panel.
40pin cable part number WTNR3 $10revised panel part number B173QTN01.4 Dell P/N: JYWWF 2560x1440 $135
40pin cable part number WTNR3 $10
revised panel part number B173QTN01.4 Dell P/N: JYWWF 2560x1440 $135
As I understand the mainboard is the same for all 17" R4 model.
Is there are somebody who has changed the panel? This is the main question.
Thank you for the reply, my friend!
I have bought LCD panel on the ebay with part number B173QTN01.4 and cable 0WTNR3.
Is it possible to determine which motherboard revision installed? My laptop has 6820HK and GTX1070 onboard and manufactured in 2017.
either way it'll work... Easiest way to test if your machine's got GSync is to goto the NVidia control panel and see if you can set it. If you don't have it, it won't be there only refresh rate settings. If you do, then you do.
I've replaced FHD lcd panel with QHD panel, and also I've replaced eDP cable to 40pin.
But, the big problem that the brightness control doesn't work!!! Has anyone had such problem?
Is it possible to resolve this issue?
