@Daedalus well I thought that till I spent a few weeks trying to get a screen working with an Nvidia card 😂 blank screens are hard to fault find , but I do love DC screens the colours are amazing. It does look nice on the AMD Firepro , just not that good as its only got 1 GB vram , it came with a 1TB 5400rpm HDD so performance is slow , but it will be built on an SSD but can't till I get this video issue sorted , I want to use this copy of Win 10 as a test bed for drivers etc before building a final version on SSD . I am on a HP 8760w with a DC screen now , never felt inverter get really hot ? it's been on for 6 hours now lots of video etc but nothing crazy and its probably warm to the hand ( 40-45c ) however I am always on 230w power supply so no heat from battery .( Ambient 20-25c ) On my old 8740w with DC the converter board behind screen was missing a heat sink pad , putting one in made the back of screen cooler as it sinked away heat better rather than a hot spot that was hot to the hand 50-55c ? Why do I get this on @GuitarG posts , do I need to VPN to see it ? I am in UK.

@JadeRover OK , that makes sense now , thank you for the explanation , I will let you know how my quest goes 😁 Regarding drivers , yes I have seen a few tutorials , looks similar to what we had to do years ago for Broadcomm Bluetooth dongles , in XP , That bit I feel confident on , but flashing with a CH341a 🙄 if I can't find a card in a couple of weeks then I may succumb to your suggestion. It's not immediate as I have this HP 8760w with a DC screen I am using now , this will be my upgrade 😊

@JadeRover Yes I agree I thought that , but was interested to know your thoughts , if I could find a seller with an HP card that was prepared to flash 84.04.9B.00.14 onto it , would this correct the DP output and would I then be able to use an unmodified driver , I would assume yes , but am I missing anything ? Some mention a whitelist on the video cards and you need a Dell card to get past it , have you come across any issues with this , I appreciate the Micro code in Main BIOS is relevant for it to recognise the card but I can't see HP putting in Dell ID's and not HP ID's ? Unfortunately the seller listing above , confirmed he had no idea what vBIOS they had and it was a generic picture , so the sticker is irrelevant 😥 So my quest goes on 🤣 I am predominantly looking for Dell M3000M now with 84.04.9B.00.14 , as you suggested , but still would be interested on your thoughts on above as you have tried MXM cards in ZBooks etc.

Thanks , I do love the colours it gives , but the brightness can hurt the eyes , unfortunately it makes doing mods like this a pain. @JadeRover seems very clued up on how and why , reading back over the thread again , now I am at my PC. I think I may have to bite the bullet and get another card , this time a Dell one with vBIOS : 84.04.9B.00.14 , just wish I had the time to play / learn how to use a chip programmer and try the different vBIOS files that I have . @JadeRover I see a few sellers on Ali express list the M3000M with vBIOS version 84.04.9B.00.14 , they also give a choice of HP or Dell , I assume they brand the card in some way , am I better to get a Dell or HP branding , would either make loading drivers after this nightmare any easier is there a downside as I assume they can't change the PID/VID values or can they ?

I think this was the right screen shot you meant , PC loads the " HP Mobile Display Assistant " for Dreamcolor displays , and that only loads if you have a DC , it has the sticker on the screen trim saying HP Dreamcolor and I can flip from 8 to 10 bit support in AMD driver.

Thank you all for the replies and ideas . I didn't reply earlier as I hadn't ticked notify me of any replies on thread via email , of the joys of getting older 😁 I agree that its probably an eDP/LVDS issue related to vBIOS but how can I find which vBIOS will work with M3000M on my HP 8770w with a Dreamcolor screen . I have tried another card from HP with vBIOS version 84.04.9B.00.07 , still exactly the same as before , returning to the AMD Firepro M4000 everything works fine. I get no crazy fan activity , it seems to act exactly as it should . This vBIOS is what I have seen suggested , even EUROCOM replied to my email and suggested this vBIOS number 84.04.9B.00.07 , I have emailed back and said " Dreamcolor compatible " hoping they can maybe help with a different version number . TechPowerUp who host some video bios files suggest compatibility with Hp 8770w ( But never mention Dreamcolor ) they have vBIOS for the M3000M but its a Dell 84.04.9B.00.07 not an HP one, they also have a Boosted up version of Dell vBIOS 84.04.9B.00.07 with better specs etc that mentions it works on HP 8770w but DO NOT mention DC screen 😐 They are it seems a lot of the time using that vBIOS with a Dell M3000M ( Are Dell cards physically different ? ) There are also Dell 7710 cards that have vBIOS 84.04.9B.00.14 on eBay that some have working on the 8770w , but I can't find anyone that specifically says : HP 8770w + Nvidia M3000M + Dreamcolor = vBIOS number xx.xx.xx.xx.xx 😤 I don't have a clip and IC program to change vBIOS or a Desktop , and would prefer not to go that route if possible , and having no display whatsoever means using NvFlash from a USB key would have to be done blind , which I definitely ain't confident to do. Anyone got some ideas on which vBIOS version I need or whether it is better to be a Dell card or HP , or is it get a Dell card with 84.04.9B.00.07 or 84.04.9B.00.14 and try them as neither HP ones I've tried work ? I was just hoping I could get a real HP card to work so drivers would be easier to do. HP says the M3000M will work in a 8770w as shown below , but they do not mention DC screen might have an issue , without a specific vBIOS , so is it the DC thats causing me issues or just the fact its a M3000M with wrong vBIOS for 8770w , irrespective of screen ? .................................................................................................................................................................

@ Vladka76 Hi , I am wondering if you can help , not sure if this is exactly the right place on your forum but I see you are discussing the HP Elitebook 8570/8770 w and Video cards with Dreamcolor displays. I have a HP Elitebook 8770w , i7 3920XM , 32GB RAM , Dreamcolor screen , BIOS F71 , Win 10 x64 I am running Legacy boot not UEFI if that matters . Initially I had an AMD Firepro M4000 video card and have changed it to a Nvidia M3000M with appropriate heatsink , however I cannot get past POST , I get no HP logo or " esc " choice to show BIOS on the Dreamcolor screen , it seems to stall at end of POST and waits , as a quick tap on power button turns it off . There is no VGA or DISPLAY PORT output , I have tried disconnecting the video cable to screen to force a VGA output but that gives me a hard stop and shutdown at end of POST. Reverting to old AMD card everything is fine. This is all the info I know about the video card , it looks perfect physically even the stickers are white and show no signs of heat : Nvidia M3000M from ZBook 17 G3 Video BIOS version : 84.04.8D.00.04 ( 900-52754-0300-000 G ) or ( 699-52754-0501-400 N ) Quadro M3000M S/N 03238 16027699 N16E-Q1-A1 HP Assy No : 806269-001 SPS 827226-001 ( Date Code : 7J16A0 ) My question is simple , should I be getting at least the HP logo or BIOS screen with this card on this VBIOS , I appreciate that I will have driver issues for Windows , but at the moment I am at a loss how to fault find what I have . Hoping someone can shed me some light on this or at least give me some pointers. I see there are ways to flash the VBIOS from a USB key using nvflash ( https://www.techpowerup.com/articles/overclocking/vidcard/34/10 ) and a VBIOS file here ( https://www.techpowerup.com/vgabios/220986/220986 ) But I am not sure if this is my problem , or if it will work as I can't get display . .
